Fish allergy 1. The most frequently reported symptoms were skin Conclusion: Our study is the first report on prevalence estimates for seafood allergy in Bushehr province. Findings indicated high prevalence of seafood allergy in student, therefore further studies and significant health concern is needed. Associations among year trends in diet , cholesterol and BMI from , observations in men and women in Northern Sweden.
An intervention program combining population- and individual-oriented activities was initiated in Concurrently, collection of information on medical risk factors, lifestyle and anthropometry started. Today, these data make up one of the largest databases in the world on diet intake in a population-based sample, both in terms of sample size and follow-up period. The study examines trends in food and nutrient intake, serum cholesterol and body mass index BMI from to in northern Sweden. Methods Cross-sectional information on self-reported food and nutrient intake and measured body weight, height, and serum cholesterol were compiled for over , observations.
Trends and trend breaks over the year period were evaluated for energy-providing nutrients, foods contributing to fat intake, serum cholesterol and BMI.
Results Reported intake of fat exhibited two significant trend breaks in both sexes: a decrease between and and an increase from women or men. A reverse trend was noted for carbohydrates, whereas protein intake remained unchanged during the year period. Significant trend breaks in intake of foods contributing to total fat intake were seen. Reported intake of wine increased sharply for both sexes more so for women and export beer increased for men. BMI increased continuously for both sexes, whereas serum cholesterol levels decreased during - , remained unchanged until and then began to rise.
The increase in serum cholesterol coincided with the increase in fat intake, especially with intake of saturated fat and fats for spreading on bread and cooking.
Conclusions Men and women in northern Sweden decreased their reported fat intake in the first 7 years — of an intervention program. After fat intake increased sharply for both genders. A relative Non-linear relationships between the exposure and the desaturase activity were not found. Consuming fish and seafood may not be translated into beneficial fatty acid profiles if the diet simultaneously causes exposure This paper discusses conceptual confusions of sustainable seafood consumption, practical challenges, and potential anchors from where this behaviour can be fostered.
The main focus lies on psychological variables. The resulting framework comprises 1 a definition of sustainable seafood consumption, 2 suggestions for corresponding behaviours, 3 the identification of facilitating and hindering factors, 4 an assemblage of these factors into a theoretical model, and 5 a short discussion of how the model adds up value to the current state of the art in marine resource conservation.
Behavioural models significantly contribute to behavioural change research. The originality and value of this research are that it tackles the so far relatively neglected field of sustainable seafood consumption as important part of sustainable development and marine conservation in the future. From an interventional perspective, the developed model facilitates the identification of contact points to approach consumers and disseminate sustainable seafood consumption among modern Western consumers.
Seafood Promotion Act of , information collected under this program is used to promote domestically Randomized trial of weight-loss- diets for young adults varying in fish and fish oil content. Thorsdottir, I. Objective: To investigate the effect of including seafood and fish oils, as part of an energy-restricted diet , on weight loss in young overweight adults. Design: Randomized controlled trial of energy-restricted diet varying in fish and fish oil content was followed for 8 weeks.
Subjects were. Seafood products are a common consumer choice and a variety of cooking methods are used in seafood preparation. Although often cooked, products such as shrimp and salmon remain some of the most common carriers of foodborne disease.
Cooking these products at elevated temperatures efficiently reduces foodborne disease causing pathogens to a safe level, but applying too much heat to seafood products can produce an overcooked, low quality food.
It is necessary to investigate the cooking proces Raw ready-to-eat seafood safety: microbiological quality of the various seafood species available in fishery, hyper and online markets. Microbiological quality of raw ready-to-eat seafood samples was investigated according to species gizzard shad, halibut, rockfish, tuna, oyster and squid and distribution channels fishery, hyper and online market. Enumeration of aerobic plate count and total coliforms TC and pathogenic bacteria Bacillus cereus, Staphylococcus aureus and Vibrio parahaemolyticus was performed, and level of microbiological quality was classified into four groups: satisfactory, acceptable, unsatisfactory and unacceptable.
Qualitative analysis was also performed for Escherichia coli and eight foodborne pathogens B. Gizzard shad was shown to be potentially hazardous, as its sashimi is eaten with its skin attached. Bacillus cereus, E. Samples from the fishery market showed higher detection rate especially in V. Raw ready-to-eat seafood products like sashimi can be easily contaminated with various bacteria from aquatic environments and human reservoirs, which subsequently bring about a risk in food poisoning due to no heating process before consumption.
The results of this study provide comprehensive microbiological data on various species of raw ready-to-eat seafood from various distribution channels. It may contribute to establish reasonable standard and effective strategies to ensure a good microbiological quality of raw ready-to-eat seafood for the. Edible films and coatings in seafood preservation: A review. Seafood is highly perishable and has a short shelf-life.
During storage many reactions occur leading to changes in quality such as endogenous chemical and enzymatic reactions. The safety and shelf-life are related to the presence of food spoilage and pathogenic microorganisms. Despite improved manufacturing facilities and implementation of effective process control procedures such as the Hazard Analysis Critical Control Point system by seafood companies, the number of seafood -related foodborne illnesses has increased.
Edible coatings can improve the quality of fresh and frozen products by retarding microbial growth, reducing lipid oxidation and moisture loss, and functioning as a carrier of food additives such as antimicrobial and antioxidant agents. Biodegradable edible coatings have various advantages over synthetic coatings such as being edible and generally being more environmentally friendly.
This paper reviews the application of various types of natural bio-polymer and different active ingredients incorporated into the films and their effects on seafood quality attributes. Prenatal mercury exposure, maternal seafood consumption and associations with child language at five years. Methyl mercury MeHg is a well-known neurotoxin and evidence suggests that also low level exposure may affect prenatal neurodevelopment. Uncertainty exists as to whether the maternal MeHg burden in Norway might affect child neurodevelopment.
To evaluate the association between prenatal mercury exposure, maternal seafood consumption and child language and communication skills at age five. Maternal mercury blood concentration in gestational week 17 was analysed in a sub-sample of women. Prenatal mercury exposure from maternal diet was calculated from a validated FFQ answered in mid-pregnancy. We performed linear regression analyses adjusting for maternal characteristics, nutritional status and socioeconomic factors.
Median maternal blood mercury concentration was 1. Blood mercury concentrations were not associated with any language and communication scales. Sibling matched analysis showed a small significant adverse association between those above the 90th percentile dietary mercury exposure and the SLAS scores. Maternal seafood intake during pregnancy was positively associated with the language and communication scales.
Low levels of prenatal mercury exposure were positively associated with language and communication skills at five years. However, the matched sibling analyses suggested an adverse association between mercury and child.
Airborne seafood allergens as a cause of occupational allergy and asthma. Occupational allergy and asthma is a serious adverse health outcome affecting seafood -processing workers. Allergic reactions are directed to two major seafood groups: fish and shellfish, with the latter group comprising crustaceans and molluscs. Several allergenic proteins have been identified in these different groups, but few have been characterised on a molecular level.
Parvalbumin appears to be the major fish allergen, while tropomyosin the major crustacean allergen. Other IgE-binding proteins have also been identified in molluscs and other seafood -associated agents e. Anisakis sp , although their molecular nature has not been characterised. This contemporary review discusses interesting and recent findings in the area of occupational seafood allergy including high-risk occupations, environmental risk factors for airborne exposures, major and minor allergens implicated and innovative approaches in diagnosing and managing occupational allergy and asthma associated with seafood processing.
Advanced glycation endproducts in 35 types of seafood products consumed in eastern China. Advanced glycation endproducts AGEs have been recognized as hazards in processed foods that can induce chronic diseases such as cardiovascular disease, diabetes, and diabetic nephropathy.
In this study, we investigated the AGEs contents of 35 types of industrial seafood products that are consumed frequently in eastern China. The level of total fluorescent AGEs in seafood samples ranged from The CML content in seafood samples ranged from The total fluorescent AGEs and CML content increased when seafood underwent high-temperature processing, but did not show an obvious correlation.
The present study suggested that commonly consumed seafood contains different levels of AGEs, and the seafood processed at high temperatures always displays a high level of either AGEs or CML.
Study on the physiological activities of gamma-irradiated seafood cooking drips. Cooking drips which were obtained as by-product after seafood processing in the food industries, still contain lost of proteins, carbohydrates, and other functional materials. This study was conducted to investigate the effect of gamma irradiation on the biological activities of seafood cooking drips.
When the cooking drips of Hizikia fusiformis, Enteroctopus dofleini and Thunnus thynnus were irradiated, the antioxidant activities, whitening effect, and angiotensin I converting enzyme inhibition activity of the ethanol extract from seafood cooking drips were all increased by gamma irradiation.
This was because of the increased extraction efficiency of available compounds by irradiation. These results suggested that the seafood cooking drips, wasted as by-products, can be used as functional compounds with gamma irradiation treatment. Due to the global challenges, it is necessary for an industrial company to integrate production scheduling and distribution planning, in order to be more efficient and to get more economics advantages.
This paper presents seafood production planning and scheduling of a seafood manufacture company which produces simultaneously multi kind of seafood products, located at Aceh Province, Indonesia. The perishability nature of fish highly restricts its storage duration and delivery conditions. Traceability is a tracking requirement to check whether the quality of the product is satisfied.
The production and distribution planning problem aims to meet customer demand subject to traceability of the seafood product and other restrictions. The problem is modeled as a mixed integer linear program, and then it is solved using neighborhood search approach. Comparison of Seafood and Agricultural Ecological Premiums1. Also ecolabeled premiums in the agricultural sector were examined. The next issue addressed was the sensitivity of changes in the price and premiums of ecolabeled seafood.
Empirical findings showed that all things being equal, consumers stated willingness to pay reflects in their actual market behavior though they may pay less than stated. Premiums observed in the aquacul Metabolic changes after a hypocaloric, low-glycemic-index diet in obese children. A low glycemic index LGI diet has been proposed as a treatment for obesity in adults; few studies have evaluated LGI diets in obese children. The purpose of the study was to compare the effects of two diets , with similar energy intakes, but different glycemic indexes in a pediatric outpatient setting.
Anthropometric and biochemical parameters were measured at baseline and after 6 months. Only LGI diets produced a significant decrease in waist circumference and homeostasis model assessment. Attribute importance segmentation of Norwegian seafood consumers: The inclusion of salient packaging attributes. The main purpose of this study is to identify consumer segments based on the importance of product attributes when buying seafood for homemade meals on weekdays.
There is a particular focus on the relative importance of the packaging attributes of fresh seafood. The results are based on a representative survey of Norwegian consumers between 18 and 80 years of age.
This study found that taste, freshness, nutritional value and naturalness are the most important attributes for the home consumption of seafood. Except for the high importance of information about expiration date, most other packaging attributes have only medium importance. Three consumer segments are identified based on the importance of 33 attributes associated with seafood : Perfectionists, Quality Conscious and Careless Consumers. The Quality Conscious consumers feel more self-confident in their evaluation of quality, and are less concerned with packaging, branding, convenience and emotional benefits compared to the Perfectionists.
Careless Consumers are important as regular consumers of convenient and pre-packed seafood products and value recipe information on the packaging. The seafood industry may use the results provided in this study to strengthen their positioning of seafood across three different consumer segments. Evaluation of the amount of Po ingested by the Spanish population and its relation to their diet habit.
In this work, the contribution of Po to the committed effective dose via ingestion received by the Spanish population have been evaluated, by determining the Po activity concentrations in an ample set of samples which can be considered representatives of the diet consumed in Spain. The obtained results show a quit high variability, preventing the possibility to fix a representative value for the Po contribution to the ingestion doses received by the Spanish population, but in general these values, due exclusively to Po, are higher than the average value assigned by UNSCEAR to the annual committed effective dose received by the worldwide population due to the ingestion of natural and anthropogenic radionuclides.
Knowing the diet habits of the Spanish population and the Po bioaccumulative behavior in the marine trophic chain, which implies enhanced concentration of Po in the sea food in comparison with the obtained ones in other components of the diet , the variable and generally higher ingestion doses due to Po received by the Spanish population can be associated to the variable and rich consumption of marine products. The Spanish population has the seafood as an essential component of his diet.
Although the Po levels in the edible parts of a great variety of marine organisms can be found in the literature in general the great majority of these determinations corresponds to raw edible products. But little is known about the effects of cooking on the Po content of seafood which are normally cooked for human consumption. Then it is important to check if cooking can alter the Po content in the seafood in order to refine the dose estimates to human consumers.
Trying to cover this gap, and at the same time trying to confirm the key role of the seafood in the Po ingestion doses received by the Spanish population, we have also analyzed the Po content in the edible parts of several seafood products bought in commercial markets. Full Text Available In the United States and the United Kingdom, over the last decade major retail chains have increasingly publicized their efforts to supply sustainably sourced and eco-labelled seafood.
Debate exists over the extent of consumer demand for this product. Seafood eco-labels purportedly resolve the information asymmetry between producer and consumer, allowing consumers who care about sustainability to easily find and purchase these products. This paper discusses the idealized model of seafood eco-labelling in promoting sustainability and presents results of US and UK case studies based on consumer interviews and surveys, which found that consumers had often seen one or more seafood eco-labels.
Two well-established eco-labels, dolphin-safe and organic, drove these rates of sustainable seafood awareness. However, eco-labels are a means to communicate messages about sustainable fisheries to consumers, not an end. Efforts to educate consumers about eco-labels should be a component of ocean literacy efforts, which educate the public about the need for sustainable fisheries.
Diet induced thermogenesis measured over 24h in a respiration chamber: effect of diet composition. It has been debated whether different diets are more or less effective in long-term weight loss success and cardiovascular disease prevention among men and women. To further explore these questions, the present study evaluated the combined effects of a high-protein, intermittent fasting, low-calorie diet plan compared with a heart healthy diet plan during weight loss, and weight loss maintenance on blood lipids and vascular compliance of obese individuals.
At the end of weight loss intervention, concomitant reductions in body weight, BMI and blood lipids were observed, as well as enhanced arterial compliance. No sex-specific differences in responses were observed. During phase 2, the high-protein, intermittent fasting group demonstrated a trend for less regain in BMI , low-density lipoprotein LDL , and aortic pulse wave velocity than the heart healthy group.
Our results suggest that a high-protein, intermittent fasting and low-calorie diet is associated with similar reductions in BMI and blood lipids in obese men and women.
This diet also demonstrated an advantage in minimizing weight regain as well as enhancing arterial compliance as compared to a heart healthy diet after 1 year. Full Text Available Ensuring the quality of food, particularly seafood has increasingly become an important issue nowadays. Quality Management Systems empower any organization to identify, measure, control and improve the quality of the products manufactured that will eventually lead to improved business performance.
With the advent of new technologies, now intelligent systems are being developed. The knowledge is represented using ontology.
The domain concepts are defined using ontology. This paper presents the initial part of the proposed model — the analysis of quality test parameter values. Two algorithms are proposed to do the analysis — Comparison Algorithm and Data Store Updater algorithm. The algorithms ensure that the values of various quality tests are in the acceptable range.
The performance of the algorithms is evaluated using standard performance metrics such as precision, recall, and accuracy. The results obtained show that all the three measures achieved good results.
Link between diet and cardiovascular disease in Latin America and the Caribbean using geographic information systems. CVD mortality rates and diet information the number of kilocalories and amount of alcohol, fats, fish, fruits, meats, sugars, and vegetables available per person daily were obtained from internationally available databases. The analyses included 32 LAC countries with sufficient data 15 of 47 had been excluded for incomplete data. Pearson's correlations r were used to determine relationships between diet and CVD mortality, and multiple linear regression analysis was conducted to identify predictors of mortality.
ArcGIS version 9. No relationships were found between CVD and alcohol, fruit, meat, sugar, or vegetable intake. Maps constructed show visual relationships between availability of fish and seafood , kilocalories, and oil-crops, and CVD mortality.
Fish and seafood , kilocalorie, and oil-crop availability appear to be related to CVD mortality, but further investigation is needed. Associations between diet and CVD mortality create the opportunity to target specific countries for nutrition education and CVD prevention programs. Concurrent engineering and product models in seafood companies.
Concurrent Engineering CE can provide an improved approach to product development for extending the lines of seafood products. Information technology IT support tools based on product models can provide an integrated and simultaneous approach for specifying new recipes. The seafood industry can The approach involves the use of product models from which line extensions are more easily generated than by use of customary stepwise Diabetes, diet -health behavior, and obesity. High-quality diets play an important role in diabetes prevention.
Appropriate dietary adherence can improve insulin sensitivity and glycemic control, and thus contribute to lifestyle improvement. However, previous research suggests that dietary adherence is arguably among the most difficult cornerstones of diabetes management.
We use data from the U. We apply propensity score matching PSM to account for selection bias and endogeneity between self-reported diet and health behavir treatment and BMI outcomes. The close relationship between diabetes and obesity has been at the center of the diet -health policy debate across Canada and the U. Knowledge about this linkage may help to improve the understanding of the factors that impact dietary choices and their overall health outcomes, which may lead to a more efficient and effective promotion of dietary guidelines, healthy food choices, and targeted consumer health and lifestyle policies.
Full Text Available This paper deals with a real-life vehicle delivery routing problem, which is a seafood product delivery routing problem. Considering the features of the seafood product delivery routing problem, this paper formulated this problem as a multi-depot open vehicle routing problem. Since the multi-depot open vehicle routing problem is a very complex problem, a method is used to reduce the complexity of the problem by changing the multi-depot open vehicle routing problem into an open vehicle routing problem with a dummy central depot in this paper.
Then, ant colony optimization is used to solve the problem. To improve the performance of the algorithm, crossover operation and some adaptive strategies are used.
Finally, the computational results for the benchmark problems of the multi-depot vehicle routing problem indicate that the proposed ant colony optimization is an effective method to solve the multi-depot vehicle routing problem. Furthermore, the computation results of the seafood product delivery problem from Dalian, China also suggest that the proposed ant colony optimization is feasible to solve the seafood product delivery routing problem.
This document on economic issues associated with seafood safety was prepared to complement the work of the Service in seafood technology, plant sanitation and Hazard Analysis Critical Control Point HACCP implementation The purposes of this study were to describe the prevalence of seafood consumption and, among consumers, the amounts of seafood eaten by sex, age group, income and education level, and race-ethnicity.
The percentages varied by socio-demographic group. Younger age and lower income and education levels were associated with lower odds of being a seafood consumer p seafood , the average amount eaten of any seafood was Among seafood consumers, women and individuals of lower age and education levels consumed less seafood. A great deal of work remains to move Americans toward seafood consumption at current recommended levels.
Moreover expression of immune-related genes was quantified by real time PCR in head-kidney leukocytes, spleen, liver, and intestine. The ToxA-Vp-treated group showed a higher anti-protease and catalase activity in skin mucus when compared with the PBS group. Interestingly, IgM levels in mucus and transcripts were enhanced followed the ToxA-Vp treatment even after challenge.
Finally, SOD and CAT gene expression was up-regulated in fish immunostimulated with either treatment ToxA-Vp or lysate-Vp, mainly after infection in head-kidney leukocytes and intestine. This is the first study where the effects of ToxA from V. These results suggest that ToxA-Vp would positively affect humoral immune response and up-regulate expression of genes involved in the immune system function; and could help in the control of V.
Temporal and spatial comparisons of the reproductive biology of northern Gulf of Mexico USA red snapper Lutjanus campechanus collected a decade apart. In studies done a decade apart, we provide evidence of a recent shift toward a slower progression to sexual maturity as well as reduced egg production, especially among young, small female red snapper , in the Gulf of Mexico Gulf.
Coincident with these changes in reproductive output, fishing pressure has steadily declined gulf-wide, and spawning stock biomass and spawning potential ratio have increased. Thus, it is possible that the age structure of the red snapper stock is becoming less truncated, or that reproductive effort observed is due to the temporary influence of recent strong year classes produced in and as they begin to reach full reproductive potential.
In contrast, if the former is true, a truncated age structure due to overharvest can limit the productivity of the Gulf red snapper stock.
In addition, we have learned that red snapper females in the northwestern Gulf collected on natural reefs and banks have much higher reproductive output than those on artificial reefs in the form of standing and toppled oil and gas platforms, thus making the need to know the relative abundance of females found on these disparate habitats an important next step toward better-understanding factors impacting the reproductive dynamics of this species.
If the latter is true, careful documentation of the stock's reproductive dynamics during a time of population growth provides new understanding at the meta-population spatial and decadal temporal scales. Amendment 18B includes an environmental assessment, a final Francisella marina sp.
Historically, piscine francisellosis in various warm, temperate and coldwater fish hosts has been attributed to Francisella noatunensis. From , an undescribed Francisella sp. Bioaccumulation of heavy metals in maricultured fish, Lates calcarifer Barramudi , Lutjanus campechanus red snapper and Lutjanus griseus grey snapper. Mariculture fish contains a rich source of protein, but some species may bioaccumulate high levels of heavy metals, making them unsafe for consumption.
This study aims to identify heavy metal concentration in Lates calcarifer Barramudi , Lutjanus campechanus Red snapper and Lutjanus griseus Grey snapper. Three species of mariculture fish, namely, L. Among all of the species under investigation, the highest concentration of Fe was found in the muscle tissue of L. Meanwhile, L. The concentration of heavy metals varies significantly among fish species and tissues. The proposed collection for scientific research involves activities However, stock size of black sea bass is below the biomass level at which the stock Bioceramics synthesis of hydroxyapatite from red snapper fish scales biowaste using wet chemical precipitation route.
Fish scales biowaste contain high collagens and calcium phosphates, therefore have considerable potential as raw material for value-added biomaterial such as hydroxyapatite HAp.
HAp is the main constituent component of hard tissue such as bone and teeth in the human body and is known as bioceramic materials. The results showed calcium content from biowaste of red snapper fish scale was Finally, Particle Size Analyzer PSA results show that the particle size distribution is evenly distributed, with the size of micro-scale hydroxyapatite particles, ranging from 5. Amendment 17A would define a rebuilding schedule of 35 years for red snapper. The rebuilding time period would end in East Coast.
We couple a species range limit hypothesis with the output of an ensemble of general circulation models to project the poleward range limit of gray snapper. Using laboratory-derived thermal limits and statistical downscaling from IPCC AR4 general circulation models, we project that gray snapper will shift northwards; the magnitude of this shift is dependent on the magnitude of climate change.
This finding argues for more experimental work aimed at understanding and parameterizing the effects of climate change and variability on marine species.
Effects of LED light spectra on oxidative stress and the protective role of melatonin in relation to the daily rhythm of the yellowtail clownfish, Amphiprion clarkii. The present study aimed to test the effects of melatonin on oxidative stress in the yellowtail clownfish, Amphiprion clarkii, as produced by light emitting diodes LEDs : red, green, and blue. SOD and CAT activities and plasma H2O2 and melatonin levels were also significantly higher for the red spectra than those for the other light spectra.
These results indicate that red light induces oxidative stress. To investigate the effects of melatonin on oxidative stress, we injected melatonin into live fish in vivo or treated cultured pineal organ in vitro with melatonin.
Therefore, our results indicate that red light induces oxidative stress and melatonin plays the role of a strong antioxidant in yellowtail clownfish. Humoral immune response and TLR9 gene expression in Pacific red snapper Lutjanus peru experimentally exposed to Aeromonas veronii. Aquaculture production of Pacific red snapper Lutjanus peru is growing rapidly in Mexico, especially in Gulf of California.
As it is a relatively new aquaculture species there are few reports evaluating its immune response to pathogens. The Gram-negative bacteria Aeromonas veronii is a heterogeneous organism that causes the disease known as motile aeromonad septicemia, which is responsible for serious economic loss in seabream culture due to bacterial infections.
For the purpose of this study, juvenile Pacific red snapper specimens were intraperitoneally injected with low doses of A. Changes in humoral immune parameters total protein, myeloperoxidase, lisozyme and antiprotease activities and IgM levels , as well as superoxide dismutase and catalase activities, and TLR9 gene expression were evaluated 24 and 48 h after injection. By real time PCR assays, the basal mRNA transcripts of TLR9 showed that were highly expressed in intestine and leucocytes compared to skin, head kidney, liver and gill.
Then, the mRNA expression levels of TLR9 in head kidney, skin, liver and intestine were analyzed in non-infected and experimentally infected fish 24 and 48 h after injection. Interestingly, intestine produced the greatest increase in transcript levels upon exposure 48 h to A.
Taken together, our results suggest that low doses of A. A morphological novelty for feeding and sound production in the yellowtail clownfish. The yellowtail clownfish Amphiprion clarkii is able to close its mouth very quickly by means of the cerato-mandibular c-md ligament, a synapomorphic trait of Pomacentridae joining the hyoid bar to the medial part of the lower jaw.
This fast closure induces tooth collision, thus producing sounds that the clownfish uses during agonistic behaviors. To investigate whether this rapid jaw movement is also used during feeding, we analyzed the kinematics of sound production and feeding.
Sound production, feeding on live planktonic prey, and feeding on food attached to tweezers was filmed with a high-speed camera. Three kinds of kinematic patterns were detected and were associated with the two different types of food presented: one performed to catch planktonic prey PP , and two called B-1 and B-2 to bite attached food items. The kinematic pattern of B-2 is similar to that observed during sound production SP and the transection of the c-md ligament highlights that sound production and biting-2 motions are dependent on this morphological trait.
Our data show that the c-md ligament in addition to its role in sound production allows duplication of the mouth-closing mechanism during feeding. This highlights the key role played by the c-md ligament in sound production and feeding on attached prey.
High connectivity in the deepwater snapper Pristipomoides filamentosus Lutjanidae across the Indo-Pacific with isolation of the Hawaiian archipelago. In the tropical Indo-Pacific, most phylogeographic studies have focused on the shallow-water taxa that inhabit reefs to approximately 30 m depth.
Little is known about the large predatory fishes, primarily snappers subfamily Etelinae and groupers subfamily Epinephelinae that occur at m. These long-lived, slow-growing species support fisheries across the Indo-Pacific, yet no comprehensive genetic surveys within this group have been conducted.
Here we contribute the first range-wide survey of a deepwater Indo-Pacific snapper , Pristipomoides filamentosus, with special focus on Hawai'i. Results indicate that P.

NMFS are looking into how increasing or decreasing black sea bass fishing effort may affect migrating Sex- and tissue-specific expression of P aromatase cyp19a1a in the yellowtail clownfish, Amphiprion clarkii. To investigate the role of estrogen in the gonad of yellowtail clownfish Amphiprion clarkii, we isolated cDNA encoding cytochrome P aromatase Cyp19a1a from the adult ovary.
The full-length cDNA of clownfish cyp19a1a is bp long and encodes amino acids. Real-time quantitative RT-PCR analysis showed that cyp19a1a was expressed mainly in the ovary of female-phase fish. In situ hybridization and immunohistochemical observations showed that positive signals were restricted to the ovarian follicle of the female-phase fish. In contrast, Cyp19a1a signal was not detected in the ambisexual gonad of the male-phase fish.
These findings suggest that Cyp19a1a is involved in oogenesis in the female-phase fish, but not in the ambisexual gonad of male-phase fish. Order Chlamydiales. Three cohorts of farmed yellowtail kingfish Seriola lalandi from South Australia were examined for Chlamydia-like organisms associated with epitheliocystis.
To characterize the bacteria, 38 gill samples were processed for histopathology, electron microscopy, and 16S rRNA amplification, sequencing, and phylogenetic analysis.
Microscopically, the presence of membrane-enclosed cysts was observed within the gill lamellae. Also observed was hyperplasia of the epithelial cells with cytoplasmic vacuolization and fusion of the gill lamellae. Transmission electron microscopy revealed morphological features of the reticulate and intermediate bodies typical of members of the order Chlamydiales.
A novel 1,bp 16S chlamydial rRNA sequence was amplified from gill DNA extracted from fish in all cohorts over a 3-year period that corresponded to the 16S rRNA sequence amplified directly from laser-dissected cysts. Phylogenetic analysis of this sequence against 35 Chlamydia and Chlamydia-like bacteria revealed that this novel bacterium belongs to an undescribed family lineage in the order Chlamydiales. Water temperature can influence the metabolic rate of ectothermal animal such as, fish.
This study aims to investigate the gastric emptying time GET of malabar blood snapper L. The gastric emptying times at different temperatures were determined X-radiographically, using barium sulfate BaSO4 as a contrast medium food marker.
The food marker and X-radiography showed that initial voidance of fecal matter began h after feeding at all temperature. The findings of this study suggest to culture L. Overall, the data obtained from this study may have important consequences for optimization of commercial production of malabar blood snapper.
Color change of the snapper Pagrus auratus and Gurnard Chelidonichthys kumu skin and eyes during storage: effect of light polarization and contact with ice. Ten gurnard and 10 snapper were stored on ice. One side always contacted the ice; the other side was always exposed to air. At different intervals for up to 12 d, the fish were placed in a light box, and the images of both sides were taken using polarized and nonpolarized illumination.
This may be a concern in quality evaluation methods such as QIM. The difference of colors between the polarized and nonpolarized images was calculated to quantify the reflection off the surface of fish. For accurate measurement of surface color and eye color, use of polarized light is recommended. Mazumder, Sabuj Kanti, E-mail: sabujsau gmail. Clonal structure in Ichthyobacterium seriolicida, the causative agent of bacterial haemolytic jaundice in yellowtail , Seriola quinqueradiata, inferred from molecular epidemiological analysis.
Bacterial haemolytic jaundice caused by Ichthyobacterium seriolicida has been responsible for mortality in farmed yellowtail , Seriola quinqueradiata, in western Japan since the s. In this study, polymorphic analysis of I. However, MLVA revealed variation in repeat numbers of three elements, allowing separation of the isolates into 16 sequence types.
The unweighted pair group method using arithmetic averages cluster analysis of the MLVA data identified four major clusters, and all isolates belonged to clonal complexes. It is likely that I. Cucullanus pargi sp. Nematoda: Cucullanidae from the grey snapper Lutjanus griseus off the southern coast of Quintana Roo, Mexico.
A new nematode species, Cucullanus pargi sp. This species shows similar morphological features as cucullanids occurring in marine and brackish-water fishes; however, it differs from all other species in the length of spicules, arrangement and number of caudal papillae, position of the excretory pore and deirids. Cucullanus pargi is the third species of this genus described from fishes in Mexico and the second one from Mexican marine fishes.
Thermal biology of prey Melongena corona bispinosa, Strombus pugilis, Callinectes similis, Libinia dubia and predators Ocyurus chrysurus, Centropomus undecimalis of Octopus maya from the Yucatan Peninsula.
On the Yucatan Peninsula there is an upwelling which allows access to a body of cold water that controls temperature in this area. This modulates the ecology and distribution of organisms that inhabit the continental shelf. The objective of this study was to determine the effect of different acclimation temperatures on the thermal biology of prey as mollusc, crustacean Melongena corona bispinosa, Strombus pugilis, Callinectes similis, Libinia dubia and predators as fish Ocyurus chrysurus, Centropomus undecimalis of Octopus maya.
Octopus prey preferred temperatures between The species with largest thermal windows were M. The acclimation response ratios ARR estimated for prey ranged from 0. Amongst predators, ARR ranged from 0. Correlating the optimal temperature limits of prey and predators with surface temperatures on the continental shelf and those 4m deep showed that the main prey, Callinectes similis and L.
As a consequence the continental shelf community would undergo a structural change. Predators were found to be near their optimal temperatures in surface temperatures on the continental shelf. We conclude that they would remain in the area in a warming scenario. The size of the thermal window was related to the type of ecosystem inhabited by these species.
These ARR intervals allowed us to categorize the species as temperate or tropical. Linking nutrient inputs, phytoplankton composition, zooplankton dynamics and the recruitment of pink snapper , Chrysophrys auratus, in a temperate bay.
Black, Kerry P. Survival of larval fish is often linked to production of preferred prey such as copepods, both inter- and intra-annually.
Hence, larval fish survival can become de-coupled from levels of nutrient input depending on the resulting composition of the plankton.
Here we use a plankton dynamics model to study nutrient input, phytoplankton composition and copepod, Paracalanus, production in relation to interannual variation in recruitment of snapper , Chrysophrys auratus, in Port Phillip Bay, Australia. The model was able to simulate the ratio of diatoms to flagellates in the plume of the main river entering Port Phillip Bay.
Interannual variability in the copepod, Paracalanus, abundance during the C. The seasonal peak in Paracalanus production depended on the timing and magnitude match-mismatch of nutrient inputs and how these were reflected in temporal change in the diatom:flagellate ratio.
In turn, the model-predicted Paracalanus abundance was strongly related to inter-annaul variability in abundance of snapper , C. Years of highest larval C. High freshwater flows and nutrient inputs led to an early seasonal dominance of diatoms, and consequently reduced abundances of copepods over the C.
Conversely years of very low rainfall and nutrient input also led to low phytoplankton and copepod concentrations and larval C. Highest abundances of larval C. Historically, piscine francisellosis in various warm, temperate and coldwater fish hosts has been attributed to Francisella noatunensis From , an undescribed Francisella sp.
Despite high mortality and emaciation, limited gross findings were observed in affected fish. Histological examination revealed multifocal granulomatous lesions, with the presence of numerous small, pleomorphic coccobacilli, predominantly in the peritoneum, spleen, kidneys, liver, pancreas, heart, and intestine. The bacteria recovered from these outbreaks were.
Phylogeographic analyses of submesophotic snappers Etelis coruscans and Etelis "marshi" family Lutjanidae reveal concordant genetic structure across the Hawaiian Archipelago. The Hawaiian Archipelago has become a natural laboratory for understanding genetic connectivity in marine organisms as a result of the large number of population genetics studies that have been conducted across this island chain for a wide taxonomic range of organisms.
Phylogeographic analyses reveal no geographic structuring of mtDNA lineages and recent coalescence times that are typical of shallow reef fauna. Population genetic analyses reveal no overall structure across most of the archipelago, a pattern also typical of dispersive shallow fishes.
However some sites in the mid-archipelago Raita Bank to French Frigate Shoals had significant population differentiation. This pattern of no structure between ends of the Hawaiian range, and significant structure in the middle, was previously observed in a submesophotic snapper Pristipomoides filamentosus and a submesophotic grouper Hyporthodus quernus. Three of these four species also have elevated genetic diversity in the mid-archipelago.
In this case the boundaries of stocks for fishery management cannot be defined simply in terms of geography, and fishery management in Hawaii may need to incorporate external larval supply into management plans. The genetic resources available for the commercially important fish species Yellowtail kingfish YTK Seriola lalandi are relative sparse. Genetic and genomic analyses were conducted using 13, single nucleotide polymorphisms SNPs generated from a new high-throughput genotyping by sequencing platform, Diversity Arrays Technology DArTseq TM in a pedigreed population comprising animals.
The linkage analysis enabled to map about 4, markers to 24 linkage groups LGs , with an average density of 3. Yellowtail Flounder Landing Limit for the U. Andrews, Kimberly R. The scallop fleet continues to use a proactive, near real-time system for avoiding yellowtail flounder; however, the negative AM for GB yellowtail flounder implements time and area closures based on the magnitude of the overage Spatio-temporal patterns of genetic variations in populations of yellowtail kingfish Seriola lalandi from the south-eastern Pacific Ocean and potential implications for its fishery management.
The genetic population structure and genetic diversity of yellowtail kingfish Seriola lalandi from the coastal south-eastern Pacific Ocean SEP were evaluated at spatiotemporal scale in order to understand the ecology of this species.
Between and , temporal and spatial population genetic structure and a low genetic diversity were detected in S. These results suggest that S. Therefore, the SEP coast might constitute a point of population mixing for this species. Additionally, the low genetic diversity of S. Regardless of the process explaining the genetic diversity and structure of S. Surimi on Cooked Shrimp. Surimi can be used as a raw material for making protein based edible coating to protect cooked shrimp color.
The purpose of this study was to determine consumers preference level on cooked shrimp which coated by surimi edible coating from red snapper and to know the microscopic visualization of edible coating layer on cooked shrimp. The treatments for surimi edible coating were without and added by sappan wood Caesalpinia sappan Linn extract.
Application of surimi edible coating on cooked shrimp was comprised methods 1 boiled then coated and 2 coated then boiled. The analysis were done using hedonic test and microscopic observation with microscope photographs. The edible coating surimi application on cooked shrimp which gave the best result was processed by boiling followed by coating.

Effects of replacing fishmeal with animal by-products meal supplementation in diets on the growth and nutrient utilization of mangrove red snapper. A feeding trial was conducted for 75 d to evaluate the nutritive value of a mixture of animal by-products MAB as a possible protein source in diets for juvenile mangrove red snapper , Lutjanus argentimaculatus mean initial body weight, 30 g.
The apparent phosphorus absorption of test diet groups was significantly higher The levels of protein and ash in the whole body, carcass and viscera increased as MAB substitution in diets increased, whereas lipids and moisture remained consistent among all treatment groups.
Farming of finfish in sea cages is gaining popularity worldwide. These systems are a suitable environment for the emergence, establishment and transmission of parasites or pathogens, such as sea lice Copepoda: Caligidae , known to cause serious diseases and economic losses in finfish aquaculture worldwide. To address this problem, a parasitological survey of economically important fish caught by artisanal fishermen was conducted between June and May A total of fish belonging to 66 species were examined.
Sea lice were found on 23 fish species. The diversity of these parasites consisted of 22 species of Caligus and 5 species of Lepeophtheirus. The most frequently encountered species were Caligus asperimanus Pearse, , Caligus mutabilis Wilson, and Caligus rufimaculatus Wilson, Taxonomic remarks are presented for some of the species recorded during this survey.
All but two sea lice records are new to Ecuador, considerably expanding the geographical range of some species. Assessment of yellowtail kingfish Seriola lalandi as a surrogate host for the production of southern bluefin tuna Thunnus maccoyii seed via spermatogonial germ cell transplantation.
Germ cell transplantation is an innovative technology for the production of interspecies surrogates, capable of facilitating easier and more economical management of large-bodied broodstock, such as the bluefin tuna. The present study explored the suitability of yellowtail kingfish Seriola lalandi as a surrogate host for transplanted southern bluefin tuna Thunnus maccoyii spermatogonial cells to produce tuna donor-derived gametes upon sexual maturity.
Germ cell populations in testes of donor T. The peripheral area of the testis was found to contain the highest proportions of dead-end-expressing transplantable Type A spermatogonia.
Fluorescence microscopy and polymerase chain reaction analysis detected the presence of tuna cells in the gonads of the transplanted kingfish fingerlings at 18, 28, 39 and 75 days after transplantation, indicating that the transplanted cells migrated to the genital ridge and had colonised the developing gonad.

Prevalence of Listeria monocytogenes in ready-to-eat seafood marketed in Thessaloniki Northern Greece. Full Text Available Aim: In the current study, a contribution to the knowledge on the prevalence and level of contamination of Listeria monocytogenes in ready-to-eat RTE seafood marketed in Thessaloniki Northern Greece was provided; the serovar identity of the L.
Materials and Methods: A total of RTE seafood samples consisting of 74 smoked fish products, 18 salted fish products, 16 dried fish products, 9 raw marinated fish products, 10 cooked marinated cephalopods and 5 surimi crab stick products were analyzed.
For the identification of serotypes a second multiplex PCR assay was used which clusters L. Results: Of the samples examined, 11 8. Only in one sample of smoked mackerel the level of L. Conclusion: This study demonstrated that L. However, the presence of this human pathogen in RTE seafood should not be overlooked, but it should be considered as having significance public health implications, particularly among the persons who are at greater risk.
Therefore, RTE seafood should be produced under appropriate hygienic and technological conditions since the product does not undergo any treatment before consumption. Seafood Technology. This presentation will fill the total picture of this conference between fisheries and aquaculture, blue biotech and bioconservation, by considering the optimal processing technology of marine resources from the raw material until the seafood reaches the plate of the consumer.
The situation today The most important aspects to be considered within seafood technology today are safety, healthy products and high eating quality. Safety can be divided into microbiological safety Seafood is healthy due to the omega-3 fatty acids and the nutritional value of vitamins, peptides and proteins.
The processing technology must however be performed such that these valuable features are not lost during production. The same applies to the eating quality. Gephart, Jessica A. Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods.
However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This ' seafood gap' in the food-water nexus literature will become increasingly problematic as seafood consumption is growing globally and aquaculture is one of the fastest growing animal food sectors in the world. Therefore, the present study 1 reviews freshwater use concepts as they relate to seafood production; 2 provides three cases to highlight the particular water use concerns for aquaculture, and; 3 outlines future directions to integrate seafood into the broader food-water nexus discussion.
By revisiting water use concepts through a focus on seafood production systems, we highlight the key water use processes that should be considered for seafood production and offer a fresh perspective on the analysis of freshwater use in food systems more broadly. Seafood products are a common consumer choice and a variety of cooking methods are used in seafood preparation.
Although often cooked, products such as shrimp and salmon remain some of the most common carriers of foodborne disease. Cooking these products at elevated temperatures efficiently reduces foodborne disease causing pathogens to a safe level , but applying too much heat to seafood products can produce an overcooked, low quality food.
It is necessary to investigate the cooking proces Prevalence of Listeria monocytogenes, Vibrio parahaemolyticus, Staphylococcus aureus, and Salmonella spp. Although several etiological agents can be transmitted through seafood consumption, Listeria monocytogenes, Vibrio parahaemolyticus, Staphylococcus aureus, and Salmonella spp. No contamination with L. The prevalence of S. Further, our findings indicate that 2. Owing to the potential hazard of these pathogenic bacteria, multiplex PCR can provide a rapid and cost-effective method for the surveillance of these pathogens in seafood products.
Other focus areas are health of young populations, to treat overweight, to prevent osteoporosis and postpartum depression The total value chain is addressed by developing consumer driven tailor-made, functional seafood products to improve health and to ensure nutritional quality and safety by full utilisation Effects of industrial processing on essential elements and regulated and emerging contaminant levels in seafood.
Mitigation of contaminants in industrial processing was studied for prawns cooked and peeled , Greenland halibut cold smoked and Atlantic salmon cold smoked and trimmed. Raw prawns had significantly higher cadmium, chromium, iron, selenium and zinc content in autumn than in spring, while Peeling raw prawns increased mercury concentration but reduced the concentration of all other elements including inorganic arsenic, total arsenic, chromium, zinc, selenium but especially cadmium, copper and iron p.
New insights into seafood allergy. Seafood plays an important role in human nutrition worldwide, sustained by international trade of a variety of new seafood products. Increased production and consumption have resulted in more frequent reports of adverse reactions, highlighting the need for more specific diagnosis and treatment of seafood allergy. This review discusses recent literature in this field.
Furthermore, the demonstration of species-specific sensitization to salt-water and fresh-water prawns and processed prawn extract should improve diagnosis. Studies on humans demonstrated for the first time that biologically active fish allergens can be detected in serum samples as early as 10 min after ingestion. These studies highlight that minute amounts of ingested seafood allergens can quickly trigger allergic symptoms; also, inhaled airborne allergens seem to induce sensitization and reactions.
In the past 2 years, over 10 additional seafood allergens have been characterized. Allergen-specific detection assays in food products are available for crustacean tropomyosin; however, many specific mollusk and some fish allergens are not readily identified. Although cross-reactivity between crustacean and mollusks as well as mites is demonstrated, the often poor correlation of IgE reactivity and clinical symptoms calls for more detailed investigations. The recent development of hypoallergenic parvalbumin from carp could form the basis for safer vaccination products for treatment of fish allergy.
Molecular characterization of more universal marker allergens for the three major seafood groups will improve current component-resolved clinical diagnosis and have a significant impact on the management of allergic patients, on food labeling and on future immunotherapy for seafood allergy.
Polycyclic aromatic hydrocarbons bioaccessibility in seafood : Culinary practices effects on dietary exposure. This work aimed to determine the effect of culinary practices on the contamination level and bioaccessibility of polycyclic aromatic hydrocarbons PAHs in seafood. The selected farmed seafood species marine shrimp, clams and seaweed were commercially available in Portugal.
The mean concentrations of PAHs varied between 0. The number of compounds detected in seaweed and clams naphthalene, acenaphthene, fluorene, phenanthrene, benzo b fluoranthene and benzo j fluoranthene were higher than in shrimp fluorene and pyrene. Among the PAHs measured, fluorene was the predominant one. According to the potency equivalent concentrations, screening values and bioaccessibility of PAHs, the consumption of marine shrimp, clam and seaweed is considered as safe for consumers.
Irradiation preservation of seafood : Literature review. The application of gamma-irradiation for extending the shelf life of seafood has been of interest for many years. This report reviews a number of studies on seafood irradiation conducted over the past several years. Topics covered include seafood irradiation techniques and dosages, species applicability and differences, the effects of packaging on seafood preservation, and changes in organoleptic acceptability as a result of irradiation.
Particular attention is given to radiation effects likely and unlikely of concern to the public. These include the potential for generation of toxic chemical products, botulinum toxin production, and other health concerns. No scientifically defensible evidence of any kind was found for any harmful effect of irradiation of seafoods at the doses being considered less than krad , and all indications are that irradiation is an acceptable and needed additional tool for seafood preservation.
A contemporary review of seafood allergy. Seafood is common item in the world diet; Asian countries have the highest rates of fish consumption in the world, which is higher than world average. Several studies have been conducted on the epidemiology and clinical characteristics of seafood allergy in different countries, and some of the fish and seafood allergens unique to those regions have been characterized.
Review on published data showed that seafood allergy is very ubiquitous in some regions of the world. Fish and shellfish are the most common seafood that cause adverse allergic reactions among nations; the symptoms ranged from oral allergy syndromes to urticaria and anaphylaxis. The major identified allergens are parvalbumin in fish and tropomyosin in shellfish.
Nevertheless, such studies are lacking from some regions with high fish and seafood consumption. Furthermore, the published data are mostly from small groups of populations, which large-scale epidemiological studies need to be performed. Preliminary results of mercury levels in raw and cooked seafood and their public health impact. Mercury is toxic for human health and one of the main routes of exposure is through consumption of contaminated fish and shellfish.
The objective of this work was to assess the possible mercury contamination of bivalves Anomalocardia brasiliana, Lucina pectinata, Callinectes sapidus , crustacean C. The effect of cooking on Hg concentration in the samples was also studied. The results showed that Hg concentration was generally higher in the cooked samples than in raw samples.
The highest concentrations were found in B. In addition, Hg values found in the other samples also suggest the monitoring of the Hg concentrations in seafood consumed from the region. Maulvault, A. The presence of cadmium Cd , lead Pb , mercury THg , methylmercury MeHg , arsenic TAs , inorganic arsenic iAs , cobalt Co , copper Cu , zinc Zn , nickel Ni , chromium Cr and iron Fe was investigated in seafood collected from European marine ecosystems subjected to strong anthropogenic.
Statement: Presence of microplastics and nanoplastics in food, with particular focus on seafood. Primary microplastics are plastics. Sum of SCCPs dry weight were in the range of ng.
Overall, the C10 and C11 homologues were the most predominant carbon groups of SCCPs in seafood from this area,and a relatively higher proportion of C was observed in seafood with higher concentrations of sum of SCCPs. Statement on the presence of microplastics and nanoplastics in food, with particular focus on seafood.
Primary microplastics are plastics There is no legislation for microplastics and nanoplastics as contaminants in food. Methods are available for identification and quantification of microplastics in food, including seafood. Occurrence data are limited.
In contrast to microplastics no methods or occurrence data in food Nanoplastics can originate from engineered material or can be produced during fragmentation of microplastic debris. Microplastics range from 0. Contaminant levels in Norwegian farmed Atlantic salmon Salmo salar in the year period from to Environmental pollutants such as dioxins and PCBs, heavy metals, and organochlorine pesticides are a global threat to food safety.
In particular, the aquatic biota can bioaccumulate many of these contaminants potentially making seafood of concern for chronic exposure to humans.
The main objective was to evaluate trends of contaminant levels in Norwegian farmed Atlantic salmon in light of the derived tolerable intakes. The fillets of these fish were homogenised and analysed for dioxins, PCBs, heavy metals and organochlorine pesticides. The levels of the contaminants mercury, arsenic, dioxins, dioxin-like PCBs and DDT in Norwegian farmed salmon fillet have decreased during our period of analyses. The levels of cadmium, lead and several organochlorine pesticides were too close to the limit of quantification to calculate time trends.
The contaminant levels in Norwegian farmed salmon have generally decreased between and Excluding other dietary sources, the levels of dioxins and dioxin-like PCBs in allowed consumption of up to 1. The group of contaminants which was the limiting factor for safe consumption of Norwegian farmed salmon, based on currently established TWI values, is the sum of dioxins and dioxin-like PCBs. Published by Elsevier Ltd. Surimi-based seafood products are widely accepted and enjoyed worldwide.
The US consumption increased in s; however, it leveled thereafter. The objectives were 1 chemical characterization of FA composition and oxidation, and 2 determination of physicochemical properties colour and texture of the nutritionally-enhanced surimi seafood. This study demonstrates that nutritional value of surimi seafood can be enhanced with concurrent improvement of colour and without affecting texture.
Risk comparisons relevant to sea disposal of low level radioactive waste. This document contains estimates of, and comparisons among, risks to human health posed by exposures to radionuclides, including those associated with low level radioactive wastes dumping at sea, and organic chemical contaminants resulting from seafood consumption.
This study was conducted at the request of the Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter the London Convention , formerly referred to as the London Dumping Convention as a component of a review of the wider political, legal, economic and social aspects of sea dumping of radioactive wastes. The highest potential risks associated with seafood consumption are generally those resulting from exposures to naturally occurring radionuclides.
The peak annual risks resulting from low level radioactive waste dumping at sea, assessed on any rational basis, are at least two orders of magnitude lower than those associated with the ingestion of common organic chemical contaminants in seafood.
Contaminant levels in Gulf of Mexico reef fish after the Deepwater Horizon oil spill as measured by a fishermen-led testing program. The BP oil disaster posed a significant threat to the U. Invertebrates shrimp, oyster, crab and other nearshore species comprised the majority of postspill testing by federal and state agencies. Deeper water finfish were sampled less frequently, despite population ranges that overlapped with affected waters.
We report on a voluntary testing program with Gulf of Mexico commercial fishermen to ensure the safety of their catch. Seven species of reef fish were tested for polycyclic aromatic hydrocarbons, several metals, and a constituent of Corexit A and A dispersants.
Only two of 92 samples had detectable levels of benzo a pyrene-equivalents a combined measure of carcinogenic potency across 7 different PAHs , which were still below federal safety thresholds. PAH ratios for these samples suggest pyrogenic not petrogenic contamination - indicating potential sources other than Deepwater Horizon.
Metals were largely absent cadmium, lead or consistent with levels previously reported mercury, arsenic. One notable exception was tilefish, which showed mercury concentrations lower than expected. We did not detect dispersant in any of our samples, indicating that it was not present in these species during the study period. Our findings suggest minimal risk to public health from these seafoods as a result of the disaster; however, the most contaminated areas were not sampled through this program.
Trends in mercury concentrations in the hair of women of Nome, Alaska - Evidence of seafood consumption or abiotic absorption? Eighty samples of hair from women of child-bearing age from Nome, Alaska, and seven control samples from women living in Sequim, Washington, were analyzed for mercury concentration by segmental analysis in an effort to determine whether seasonal fluctuations in mercury concentration in the hair samples can be correlated to seasonal seafood consumption.
Full-length hair strands were analyzed in 1. It was assumed that the concentration of mercury in each segment is an indicator of the mercury body burden during the month in which the segment emerged from the scalp. Eighteen of the samples show seasonal variability, with five of the controls and one Nome resident showing winter highs while all Nome residents show summer highs.
Twenty-six of the samples show an increase in mercury concentration toward the distal end of the strand regardless of month of growth. The trend of increasing mercury concentrations toward the distal end of the hair strand regardless of month of emergence, and the documented presence of elevated levels of elemental mercury in the Nome area suggest that these elevated levels may actually be due to external contamination of the hair strands by adsorption and not due to ingestion of contaminated foodstuffs such as seafood.
Prevalence of potentially pathogenic Vibrio species in the seafood marketed in Malaysia. Seafood samples obtained in seafood markets and supermarkets at 11 sites selected from four states in Malaysia were examined for the presence of nine potentially pathogenic species from the genus Vibrio between July and June We examined sample sets that included shrimp, squid, crab, cockles, and mussels. We extensively examined shrimp samples from Selangor State to determine seasonal variation of Vibrio populations.
Eight potentially pathogenic Vibrio species were detected, with overall incidence in the samples at 4. As many as eight Vibrio species were detected in shrimp and only four in squid and peel mussels.
Of 97 strains of V. The results indicate that the various seafood markets in Malaysia are contaminated with potentially pathogenic Vibrio species regardless of the season and suggest that there is a need for adequate consumer protection measures.
Full Text Available Within the discussion around sustainable diets, seafood consumption is still a relatively neglected field. This article discusses relevant behaviours consumers can perform to consume seafood sustainably. The predictive power of intention, descriptive social norms, trust, awareness and pro-environmental attitudes are theoretically discussed and statistically tested across two studies in regards to a using sustainable seafood labels, and b using sustainable seafood guides.
The variables predicting seafood guide use are less stable which might be due to this behaviour being performed by a very small fraction of consumers only. Causal relationships have been identified in study 2 by applying cross-lagged panel analyses between intentions, trust and social norms and seafood label use.
Further causal relationships were found between intentions, trust and awareness and seafood guide use. A bidirectional relationship was confirmed between descriptive social norms and seafood guide use. Potential strategies to promote seafood label- and seafood guide use, are discussed based on these results.
Raw prawns had significantly higher cadmium, chromium, iron, selenium and zinc content in autumn than in spring, while summer levels typically were intermediate. Peeling raw prawns increased mercury concentration but reduced the concentration of all other elements including inorganic arsenic, total arsenic, chromium, zinc, selenium but especially cadmium, copper and iron p processing was observed. Hence inorganic arsenic was low Processing salmon did not significantly change any levels calculated both per wet weight, dry weight or lipid content.
Since , the French fishery field has had to cope with a levelling off of consumption of fresh seafood products whereas the consumption of processed seafood products is increasing. Nowadays, consumers prefer easier products: fresh deli products, easy to cook or ready to consume. Therefore, fresh seafood products do not seem to fulfil current consumer demand intrinsically aspect, taste and extrinsically cooking methods, use, origin, brand and price. In order to understand the evolution A short food frequency questionnaire to assess intake of seafood and n-3 supplements: validation with biomarkers.
Full Text Available Abstract Background Seafood intake is associated with beneficial effects for human health. Valid assessment of dietary seafood and n-3 supplement intakes are becoming increasingly crucial when giving recommendations to populations as seafood consumption is regarded as an important part of a healthy and balanced diet.
Methods The aim was to validate a short FFQ developed for assessment of dietary intake of seafood and n-3 supplements using the biomarkers marine n-3 fatty acids in erythrocytes and 25 OHD in serum. Full Text Available Levels of sixteen polycyclic aromatic hydrocarbons PAHs in 30 edible tissues of selected frequently-consumed fish and seafood collected from three coastal waters of Niger Delta, namely, Sime, Kporghor and Iko were investigated in Gas chromatographic analysis were employed for PAHs determination.
Observed mean PAHs levels in the samples ranged from below detection limit BD of analytical instrument to The highest average concentration of Occupational allergy due to seafood delivery: Case report. However, even in jobs with limited direct exposure, individuals with atopic disposition not using appropriate skin protection are at risk for developing occupational seafood allergy which requires termination of employment.
Case presentation Due to increasing workload and pressure of time a truck driver in charge of seafood deliveries for 10 years neglected preventive measures such as wearing protective cloths and gloves which resulted in increasing direct skin contact to seafood or mucosal contact to splashing storage ice.
Despite his sensitization to fish and crustaceans he tried to remain in his job but with ongoing incidental allergen exposure his symptoms progressed from initial contact urticaria to generalized urticaria, anaphylaxis and finally occupational asthma. Conclusion Faulty knowledge and increased work load may impede time-consuming usage of preventive measures for occupational health and safety. In predisposed atopic individuals even minor allergen exposure during seafood distribution may lead to occupational seafood allergy.
With ongoing allergen exposure progression to potentially life-threatening allergy symptoms may occur. Scientific Opinion on health benefits of seafood fish and shellfish consumption in relation to health risks associated with exposure to methylmercury. The Panel concluded that consumption Levels of sixteen polycyclic aromatic hydrocarbons PAHs in 30 edible tissues of selected frequently-consumed fish and seafood collected from three coastal waters of Niger Delta, namely, Sime, Kporghor and Iko were investigated in Human food chain contamination.
The case of seafoods in France in The global and individual levels of contamination by cesium resulting from consumption of sea products fish, crustaceans, molluscs in France were determined. Statistical data are first presented: catches, transformations, distribution and consumption.
The exchanges between some fishing and consumption areas were then quantified. Global and individual contaminations at the national and regional levels were then assessed. They are associated with various water concentrations of cesium in the marine environment. Regional differences appear clearly; they are explained mainly by consumption habits and also by the choices of fishing areas and the features of market distribution.
