Full textAbstract:
Fish health protection is a complex and permanent measure veterinary specialists are taking in order to preserve and improve breeding and production of particular fish species and categories. The system of monitoring fish health should ensure early detection of disorders in fish health and the presence of causing agents. In order for the monitoring to be efficient it should be practiced in accordance with the specific conditions of each system and breeding venues, as well as to the specific health problem needs of different farmed fish species. The most important issue in fish diseases diagnostics is the systematic monitoring of the condition offish health. Only in such way it is possible to detect a disease on time and then determine the adequate therapeutic and other necessary measures. In dealing with the problems offish pathology in carp fishponds, the epizootical situation of disease spreading caused by different agents (viruses, bacteria, fungi and parasites) has been examined. The most frequent diseases among the farmed carps in the examined fish ponds in Vojvodina area, described in this paper were: carp pox, spring viremia of carp, carp erythrodermatitis, aeromonas and pseudomonas infections, bacterial gill disease, diseases caused by ecto- and endoparasites and gill necrosis. Based on the obtained results, modern diagnostic methods were implemented and proper prevention and successful therapy of the diseases causing the greatest loss in farmed fish populations was taken.

Aquaculture represents the fastest growing animal husbandry in many countries. However, higher intensity of fish farming can pose higher health hazards, too. We monitored the health status of fish from one fish farm in South Bohemia and discovered the main health problems in the breeding. For two years we examined a total of 224 specimens of brook trout (Salvelinus fontinalis), 126 specimens of hybrids (S. fontinalis×S. alpinus), 49 specimens of rainbow trout (Oncorhynchus mykiss) – all clinically healthy, and 100 clinically diseased or freshly dead fish. We registered skin erosions mainly in the caudal peduncle and tail fin. Two parasite species were identified (one protistIchthyophthirius multifiliisand one nematodeRaphidascaris acus) by parasitological examination. The epidemiological indicators ofI. multifiliiswere low. The prevalence of adultR. acuswas 0–86% with a maximum in June. From November, capsules with larval stages ofR. acusappeared in internal organs. Their highest intensity (200 pieces) and prevalence (100%) were detected in October. By microbiological examination of skin and gills, we identified changes in the density of bacterial population and its species composition dependent on water temperature and fish density. The most important problem on the monitored fish farm seems to be furunculosis of salmonid fish in all clinical forms, and the high intensity of larval stages ofR. acus. The originality of this study is based on the fact that the observed breeding employs the first Danish recirculation system in the Czech Republic and no recent information about health problems has been available.

Full textAbstract:
Foodborne diseases caused by multiple etiologic agents are prevalent worldwide affecting both sexes and all age groups. Clonorchiasis is considered as an emerging major foodborne disease of public health problem as about 35 million people are infected globally. It is a foodborne helminthic zoonosis of a greater socioeconomic importance in several countries of Asia. The disease is caused by Clonorchis sinensis, which is a trematode. The infection occurs by the consumption of raw or inadequately cooked fish contaminated with metacercaria of the parasite. The clinical spectrum of disease in humans depends on the burden of parasites. In severe infections, jaundice, cholangitis, ascites, cholecystitis, formation of gall stone, and gastrointestinal bleeding are observed. Maximum cases are observed in males than females, and infection is serious in elderly persons. The diagnosis of disease can be confirmed by parasitological technique. Presently, praziquantel is the drug of choice as it has shown high cure rates in endemic areas. The education campaigns regarding the consumption of properly cooked fish and avoidance of faecal matter to ponds as a fish food are practical strategies that may help to control the disease.

Aquaculture represents the fastest growing animal husbandry in many countries word-wide. Intensive fish production has increased the risk of infectious diseases all over the world. Bacterial pathogens probably cause most disease problems in aquaculture. Most infectious bacterial diseases in commercial fish species continue to be controlled by treatment with chemotherapeutic agents although they represent a potential environmental hazard and could also have negative effects on the quality of the final product. The most important problem of antibiotic treatment is the increase in resistant bacteria, the presence of their residues in aquaculture products and the resulting threat to human health. Therefore, it is most effective to prevent the introduction or onset of the disease. Beside preventing the introduction of pathogens, good water quality, reduction of environmental stressors, adequate nutrition and immunization, many substances improving the health status of fish, such as immunostimulants, probiotics, prebiotics, symbiotics and so on, are used in fish breeding. The present review gives an overview of preventive and prophylactic substances which can be used in salmonid fish breeding to improve the health status of fish.

ABSTRACT The Problem Oil Pit (POP) multiagency effort in the U.S. Environmental Protection Agency Region VIII and U.S. Fish and Wildlife Service Region VI has resulted in success at remediating and cleaning up hundreds of oil covered pits in oil production fields in six western states. The installation of exclusionary devises at many of these pits will ensure the safety of birds and wildlife for years to come. A heightened awareness of environmental protection standards and regulations by the oil and gas exploration and production industry will increase compliance and enhance management of facilities in an environmentally protective manner toward public health and resources for future generations. In this effort, the federal, state, and tribal partners used their own regulatory tools on the problems and compliance issues encountered. This poster presentation will highlight the achievements of the POP effort by showing photographically and statistically the results of the POP effort: sites cleaned up, abatement of threats to birds and wildlife by exclusionary devices installed, and achievement of compliance with federal, state, and tribal environmental regulations.

Full textAbstract:
SummaryIn order to determine whether mercury from distant goldmining affected health in the districts of lranduba and Barreirinha, Amazonas State, Brazil, mercury in the scalp hair of 101 peasants (39 males and 62 females) was determined by cold vapour atomic absorption. In both areas fish is the major source of dietary protein. The average hair mercury content was 38.6 ppm (1SD = 14.1) in Barreirinha, where the diet contains a high proportion of carnivorous fish, and 5.6 ppm (1SD = 3.1) in Iranduba, where the diet contains more herbivorous fish. The levels found in women's hair in Barreirinha are particularly critical in view of the evidence that peak maternal hair mercury levels above 70 ppm are associated with 30% of risk of neurological disorder in the offspring, and that 5% risk may be associated with a peak mercury level of 10–20 ppm in the maternal hair (WHO 1990).The health of many people, and thus forest preservation, are threatened. An environmental monitoring and health programme is urgently needed for the Brazilian Amazon. Dietary assessment could be a useful indicator of the risk of mercury poisoning, if taken together with periodic analysis of mercury contents of commonly eaten fishes and of scalp hair, particularly that of young and pregnant women. Environmental monitoring is pointless if not directed at effective action; and a planning approach to this is suggested which includes a major educational component.

Full textAbstract:
In Ghana there are concerns that antibiotics may be used inappropriately to boost fish production, though no study has investigated this problem. To provide preliminary insights into public health aspects of the problem, we investigated the occurrence of antibiotic residues and antibiotic-resistant bacteria in Nile tilapia (Oreochromis niloticus), a fish commonly cultivated and consumed in Ghana. Two hundred Nile Tilapia fish were randomly sampled from four major markets in Accra, the capital city of Ghana. One hundred samples were screened for antibiotic residues using a microbial inhibition plate test that detects sixteen different antibiotics commonly used in animal husbandry and aquaculture. The other 100 samples were cultured for bacteria using direct culture methods, and the isolates were tested against seven antibiotics by the Kirby Bauer method. The overall prevalence of antibiotic residues in the fish samples was 7%. Bacteria that were isolated from the fish samples were Shigella sonnei (10%), Enterobacter cloacae (7%), Escherichia coli (6%), Salmonella Typhi (3%) and Klebsiella pneumoniae and Proteus mirabilis (2%). All bacteria isolated were susceptible to gentamicin and ciprofloxacin but resistant to ampicillin. Multi-drug resistance (ie resistance to three or more different classes of antibiotics) occurred in 86.7% of the isolates. Nile Tilapia sold in Accra is a source of multi-drug resistant bacteria. Consumption of the fish can also lead to significant exposure to antibiotic residues.

This study was performed to understand the constraints of health management of commerciallycultured high value fishes including gulsha (Mystus cavasius), shing (Heteropneustes fossilis) and koi (Anabastestudineus). One hundred farmers were interviewed through structured questionnaire in Mymensingh andJashore districts. Most of the farmers practiced polyculture of gulsha and shing with carps and monocultureof koi high densities. All the three species suffered from a number of serious diseases under farmingconditions. Most prevalent clinical signs of diseases were ulcerative hemorrhagic lesion, whitishappearance over body surface, ventral and mouth reddening and fin rot. The most susceptiblespecies to disease was shing with a higher average mortality of 43.33% followed by gulsha(36.71%) and koi (38.76%). Diagnosis of disease was the single most important constraints ofhealth management followed by lack of farmer’s knowledge on fish health and diseases, presence ofhuge number of poor quality medicine, ineffectiveness and indiscriminate use of such medicine,lack of farmer’s ability on application of medicine and absence of qualified fish health adviser.Lack of good quality fish seed, feed and water were identified as the main resource problemsassociated with fish health management. The study also identified a number of general constraintsof farming of high value fish which included low price of fish, higher feed cost, and outbreak ofdiseases, high land tax, electricity bill and marketing problem. Further studies should focus on thedevelopment of strategies for better health management practices for sustainable commercial cultureof high value fishes.

Full textAbstract:
AbstractObjectiveTo evaluate if and how the current degree of scientific uncertainty about the safety of fish consumption is incorporated at the media level.DesignWe used a dedicated software (TalTac®) to investigate the content of 169 news articles related to ‘mercury and fish consumption’ that appeared from 1990 to 2010 in the two Italian broadsheets with the highest circulation figures, in order to identify journalistic frames used in the coverage of benefits v. risks associated with fish consumption. Hypotheses were made on how the public might change fish consumption patterns as a result of media coverage.SettingItaly.ResultsThe two newspapers have different agendas in covering the issue. La Repubblica appears to support the view that, besides health benefits, there may be risks associated with fish consumption, while Corriere della Sera emphasizes health benefits more than possible risks. Depending on the preferred information source, the public could: (i) reduce its fish intake; (ii) increase its fish intake; or (iii) become confused about the problem and sceptical towards the media, as a result of conflicting journalistic frames.ConclusionsThe Italian media, in cooperation with scientists, public health nutritionists and dietitians, should place more emphasis on the existence of a few fish species with high to very high Hg levels and relatively low contents of beneficial n-3 fatty acids (e.g. swordfish and shark). This would enable consumers to make more educated purchasing decisions to maximize the benefits of n-3 intake while reducing possible risks from consuming Hg-contaminated fish.

Full textAbstract:
Marine fish species infested with Anisakidae larvae are reported in many fishing grounds. Besides the problems related to consumer’s health when the live larvae are ingested (anisakidosis) or to allergic problems caused by the larvae, the products excreted/secreted or released by the larvae are recognized as proteases, protease inhibitors or antioxidants, which can cause changes in fish muscle during storage. To study this problem, live larvae or a homogenate of larvae in water were added in controlled conditions to gelatin agar gels and minced fish muscle and stored at 20 or 5 °C for 7 days. A high activity in the gelatin agar gels was observed, whereas the inclusion of larvae or larvae homogenates in the muscle did not produce detrimental changes in texture, viscosity, color, or oxidation of fish muscle. The electrophoretic pattern of the extracted natural actomyosin presented fewer changes during storage in the larvae and larvae homogenate added lots than in the control lots. Nevertheless in naturally infested fish different parasite-host mechanisms might be involved. Parasitized fish has to be processed with treatments which kill the larvae to avoid consumers’ anisakidosis. However, as some of the Anisakis allergens are very stable to heat, patients allergic to Anisakis sp. have to be informed before ingesting parasitized fish or fish products.

Full textAbstract:
The contamination of aquatic systems with heavy metals is affecting the fish population and hence results in a decline of productivity rate. River Kabul is a transcountry river originating at Paghman province in Afghanistan and inters in Khyber Pakhtunkhwa province of Pakistan and it is the major source of irrigation and more than 54 fish species have been reported in the river. Present study aimed at the estimation of heavy metals load in the fish living in River Kabul. Heavy metals including chromium, nickel, copper, zinc, cadmium, and lead were determined through atomic absorption spectrophotometer after tissue digestion by adopting standard procedures. Concentrations of these metals were recorded in muscles and liver of five native fish species, namely,Wallago attu,Aorichthys seenghala,Cyprinus carpio,Labeo dyocheilus, andOmpok bimaculatus. The concentrations of chromium, nickel, copper, zinc, and lead were higher in both of the tissues, whereas the concentration of cadmium was comparatively low. However, the concentration of metals was exceeding the RDA (Recommended Dietary Allowance of USA) limits. Hence, continuous fish consumption may create health problems for the consumers. The results of the present study are alarming and suggest implementing environmental laws and initiation of a biomonitoring program of the river.

Full textAbstract:
Foodborne diseases are considered an important public health problem at a global level due to their levels of incidence and mortality as well as their negative consequences in economic and social aspects. Foodborne diseases are defined as those that are generated by the ingestion of food and water contaminated by chemical or biological agents commonly affecting health at the level of the gastrointestinal system. Among the risks and dangers to health from food are the diseases caused by Clostridium perfringens, a common bacterium which inhabits water, soil, vegetables, fish, the gastrointestinal system of human and animals and of course foods. The importance of this bacterium in health and food lies both in its cosmopolitan distribution, ability to generate heat-resistant spores and food poisoning, which makes control and prevention actions indispensable along the food chain. This article presents a general description of foodborne diseases, including those caused by consumption of food, such as fish, derived from contamination by C. perfringens; likewise, the actions and recommendations undertaken around the world for the prevention and control of these diseases are shown, including aspects related to the antimicrobial resistance phenomenon and its impact on public health.

Full textAbstract:
This study examined culturable skin microbiota that was associated with farmed European seabass (Dicentrarchus labrax). Healthy European seabass were sampled during summer commercial harvest from one conventional fish farm where antibiotics are used, and from another practicing a certified antibiotic-free fish aquaculture. Physicochemical and microbiological analysis of seawater and sediment were performed, as well as determination of culturable bacteria, including Vibrio, from skin swabs of European seabass and seawater and sediment at both farms. Samples were processed for isolation of bacteria and their characterization by molecular and antibiotic susceptibility tests. In both fish farms, most of the bacteria that were identified in the skin belonged to the genera Pseudomonas and Vibrio. Some of the microbiota that were identified are known to be pathogenic to fish: V.alginolyticus, V. anguillarum, and V. harveyi. Vibrio strains showed higher resistance to certain antibiotics compared to previous studies. This study provides, for the first time, information on the culturable skin bacteria that is associated with healthy European seabass under culture conditions with and without the use of antibiotics. This information will be useful in assessing how changes in culturable microbiota may affect the health of farmed European seabass, indicating a potential problem for fish health management during disease outbreaks.

AbstractObjectiveTo explore the terms on which nutrition should engage with the global challenges ahead.DesignAnalysis of current orientation of nutrition and policy.ResultNutrition faces four conceptual problems. The first is that nutrition has fissured into two broad but divergent directions. One is biologically reductionist, now to the genome; the other sees nutrition as located in social processes, now also requiring an understanding of the physical environment. As a result, nutrition means different things to different people. The second problem is a misunderstanding of the relationship between evidence, policy and practice, assuming that policy is informed by evidence, when there is much evidence to the contrary. The third problem is that nutrition is generally blind to the environment despite the geo-spatial crisis over food supply, which will determine who eats what, when and how. How can we ask people to eat fish when fish stocks are collapsing, or to eat wisely if water shortage dominates or climate change weakens food security? The fourth problem is that, in today's consumerist and supermarketised world, excess choice plus information overload may be nutrition's problem, not solution.ConclusionNutrition science needs to re-engage with society and the environment. The alternative is, at best, to produce an individualised approach to public health or, at worst, to produce brilliant science but be policy-irrelevant.

Food safety is considered an essential characteristic of food quality and is one that establishes that food, when ingested, will not cause harm to the consumer's health. Foodborne diseases are considered a health problem worldwide due to their incidence and mortality; these diseases have different causal agents of a physical, chemical and biological nature, being the latter mainly related to disease outbreaks where they are included (viruses, bacteria, parasites, and fungi), generally affecting low-income population groups, children, the elderly, pregnant women, and immunosuppressed. This review focused on giving a general description of food-borne diseases, mainly those developed in fish, highly nutritious food that is highly susceptible to deterioration and contamination by various chemical and biological hazards. Among the fish with the highest production for marketing and consumption is tilapia, which can be a vehicle for transmission of various pollutants of biological origin, including Helicobacter pylori, which has been considered an emerging food pathogen with a considerable impact on human health, whose food contamination and infection may be due to different factors such as inadequate hygiene practices at different stages of the food chain, putting the safety of these foods, and/or the health of consumers at risk.

Environmental pollution and its effects on the health of aquatic ecosystems is a great problem that has been studied intensely in the last years. The Vygozero reservoir is one of the largest water bodies of the Karelian Republic. Its ecosystem has undergone significant changes since the 1930s mainly due to anthropogenic influence from the development of pulp and paper mill industry leading to accumulation of toxic contaminants and eutrophication. At present, the water body has been shown to be also polluted by hydrocarbon products and heavy metals. Among the huge changes in Vygozero ecosystem is the decrease of some fish populations and partial loose of commercial fishing importance. Despite the obvious changes in fish population the chronic biological effects of the Vygozero reservoir pollution on fish organism are poorly studied. This study is concerned with the evaluation of pollution influence on fish health status and establishment relation between fish health and environmental quality. The parameters selected for this aim were the occurrence of gills, liver and kidney alterations, as histopathological changes are widely used as biomarkers in the evaluation of the health of fish exposed to contaminants. Our findings confirm chronic pollution of the Vygozero reservoir. Histological analysis of fish tissues revealed a variety of progressive, regressive, inflammatory, circulatory disturbances and neoplastic changes. Observed histological alterations indicate that organism of fish from Vygozero reservoir responses to the impaired environment quality. Revealed histopathologies are sings of metabolic disorders, immunity suppression, compensatory reactions development and functional abnormalities in vital organs of studied fish. The results of the study correspond to the prior research devoted to ascertain tissue changes in different fish species taken from an area with chronic multiple anthropogenic impact. So it can be concluded that histopathological lesions are result of long-term effect of toxic xenobiotics.

An important problem of modem society is the provision of the population with ecologically clean food products in quantity, range and quality, which guarantees an increase in their living standards and preservation of health. The solution to this problem is possible with the effective functioning of food market, dynamic development of agro-industrial complex, including production of marketable fish. Significant reserves for increasing fish production are water bodies existing in rural areas and new ponds being built on lands unsuitable for growing agricultural crops. As practice shows, when using inconvenient land for animal husbandry, we can get the following increase in cattle meat (kg/ha): in low-lying wetlands – 42, steppe, semi-steppe, desert pastures – 20. At the same time, from 1 hectare of pond mirrors built on such lands, an average of 200-300 kg of fish is obtained due to natural fish productivity, and with the use of fertilizers, various methods of reclamation and feeding fish up to 1000-1500 kg/ha. However, on the way to increasing fish productivity is the problem of ensuring water quality of the water body. Thus, the study of the causes and sequence of stages of pollution of water bodies determined the relevance of the research topic [1-3].

The sustainability of fishery is a global challenge due to overfishing and reduced stocks all over the world; one of the leading factors of this threat is fish loss/waste. As a contribution to the global efforts towards a sustainable world, this review addresses the topic from different sides and proposes an overview of biorefinery approaches by discussing bioactive compounds that could be produced from fish loss (nitrogen compounds, lipids, minerals and pigments, and fish-based compounds such as chitosan). The second part of this review reports on the possibility of using loss or unwanted fish to design products for human consumption or for animal feeding, with a focus on economic criteria, consumers’ segmentation, and some examples of products. The final focus is on Food and Agriculture Organization FAO guidelines as a roadmap for the future with respect to solving this threat by addressing the problem from different sides (technology, skills, market, policy, social and gender equity, and infrastructures).

Full textAbstract:
The demand for Indonesian opah fish as an export product is increasing in the international market. Three countries (Malaysia, Mauritius, and Taiwan) recorded as the leading export destination of Indonesian opah fish. However, as the fish kept in a frozen state during export transportation, the endogenous formaldehyde may increase over time. This research presented the health risk assessment of population in the leading export destination countries that consumed opah fish from Indonesia. The study aimed to reveal the most potential export destination country that may accept an increasing volume of opah fish supply from Indonesia. The potency was determined from current export volume, the amount of endogenous formaldehyde content, and fish consumption at each country. The data were calculated with @Risk®7.0 software. The results showed opah fish consumed by Malaysian can be categorized as safe. Increasing the number of opah fish imported by Malaysian as much as six times, 12 times, 18 times, 27 and 36 times relatively does not cause health risks related to the presence of its endogenous formaldehyde. Moreover, opah fish consumed by Taiwanese is also safe, but with increasing the number of consumptions by more than 26 times is suspected to be potentially causing a health problem. However, opah fish consumed in Mauritius was categorized as unsafe and potentially caused health risks. Based on these results, Indonesia may consider to increase the opah fish export to Malaysia and Taiwan in the future.

Full textAbstract:
Fish despite their low collocation in the vertebrate phylum possess a complete immune system. In teleost fish both innate and adaptive immune responses have been described with melanomacrophage centers (MMCs) equivalent to mammalian germinal centers. Primary lymphoid organs are represented by the thymus and kidney, while spleen and mucosa-associated lymphoid tissues act as secondary lymphoid organs. Functions of either innate immune cells (e.g., macrophages and dendritic cells) or adaptive immune cells (T and B lymphocytes) will be described in detail, even including their products, such as cytokines and antibodies. In spite of a robust immune arsenal, fish are very much exposed to infectious agents (marine bacteria, parasites, fungi, and viruses) and, consequentially, mortality is very much enhanced especially in farmed fish. In fact, in aquaculture stressful events (overcrowding), microbial infections very frequently lead to a high rate of mortality. With the aim to reduce mortality of farmed fish through the reinforcement of their immune status the current trend is to administer natural products together with the conventional feed. Then, in the second part of the present review emphasis will be placed on a series of products, such as prebiotics, probiotics and synbiotics, β-glucans, vitamins, fatty acids and polyphenols all used to feed farmed fish. With special reference to polyphenols, results of our group using red grape extracts to feed farmed European sea bass will be illustrated. In particular, determination of cytokine production at intestinal and splenic levels, areas of MMCs and development of hepatopancreas will represent the main biomarkers considered. All together, our own data and those of current literature suggests that natural product administration to farmed fish for their beneficial effects may, in part, solve the problem of fish mortality in aquaculture, enhancing their immune responses.

Full textAbstract:
Trichiurus Lepturus constitute one of the most important commercial fishes of India. Nowadays the major health problem arises due to malnutrition and lack of excellent sources for the nutrient food supply. Fisheries are one of the most promising healthy food sources that humans and other animals depend. Hence nutrient profiling is important to know the calorific value of food for the edible purpose. This study was aimed to find the nutritional quality evaluation of the fish Trichiurus lepturus collected from Cochin, Kerala and to suggest the calorific value of fish Trichiurus lepturus . It was found that the fish Trichiurus lepturus is a chief source of fats and proteins. The high concentration of fat may be an indication of high calorific value than compared to other fishes since the portion of calorific value lead by fat more.

Full textAbstract:
The hygienic and sanitary conditions of majority of the retail fish markets are very poor and unhealthy that may have an impact on fish retailers. The present study was conducted in two retail fish markets located in Kajirbazar and Bondorbazar, in Sadar Sylhet, to assess the hygiene and sanitary condition of fish retailers. Information was collected through questionnaire interview and participatory rural appraisal (PRA) from the retailers and other value chain stakeholders. It was found that about 82% of fish retailers were permanent in these retail markets. The retailers are mainly involved in selling various species of fishes such as carps, catfishes, tilapia, koi, hilsa, shrimp and other small indigenous fishes. The sources of these fishes are mainly of nearby haors, river and ponds. The retailers get fishes from various suppliers and also collected from producers. The income level of fish retailers is relatively low although they are trying to improve their socio-economic conditions. Besides, about 9% of the retailers do not have any formal education whereas 70% and 21% have their education in primary and secondary level, respectively. Although the majority of the retailers were found literate, however, their knowledge on public health was seemed to be very poor. Due to lack of proper knowledge on public health, they are frequently affected by various diseases such as common cold, diarrhea, lesion, fever, skin disease and so on. Particularly, 48% of the fish retailers are affected by the lesion on hands, and 31% and 27% of retailers have been affected by the lesion between fingers or toes, respectively. About 20% of the retailers do not have adequate knowledge on fish quality or benefit of using ice in fish preservation in retail markets. Considering all together, the present study revealed that the retailers operated fish markets are ill-managed, unhygienic and unsatisfactory. The lack of proper fish preservation facilities, poor water supply and unplanned infrastructures are generally regarded as a noticeable problem in the retail markets. In addition, the lack of retailer’s education, consciousness about fish quality, lack of training on hygienic and sanitary conditions are seemed to be involved in spoiling or deteriorating fish quality before reaching to the consumers. Therefore, the proper education and training on hygienic and sanitary conditions as well as sufficient knowledge on maintaining fish quality is required for retailers involved in fish retailing in the markets. It can be concluded that the improvement of relevant facilities of fish markets and proper supervision by respective authorities can ensure the better public health for retailers and safe fish food for consumers.

The fishery of the Caspian Sea basin plays an important role in providing the Southern Federal District population with food. Along with the coastal and marine fishery development due to the new area assimilation and underutilized facilities, the aquaculture production is a promising direction for the fishery development of the Southern Federal District. A man suggests to solve the efficient utilization problem of pond fish by developing relatively cheap, but high-quality public catering products, particularly various semi-finished products. When processing pond fish into minced fish, it is possible to obtain products of different quality classes differing in color, consistency, possible shelf life, and direction of use. Improving the minced fish production technology discovers new, more rational and modern ways of processing fish raw materials: processing into minced fish solves the production economic task, production of minced fish culinary products both natural and with additives enables expanding the fish products range on the Russian market. At the same time, a man solves the technological problem: since the pond fish has many small bones, when ground into minced fish, small bones either remain in the separator or are very finely minced; at the same time, the fish edible part yield reaches 40-60%, whereas when filleted is only 28-33%. As for the market, in recent years, consumer interest in food products that contain ingredients beneficial to human health has increased. The processing of pond fish into minced fish and the development of products based on it fall into the modern food market structure in general and the fish market in particular.

Full textAbstract:
SUMMARYAs there is little evidence of pollution affecting the health of fish and shellfish on a global scale, this paper attempts to put into perspective the pollution/fish disease relationship by reviewing examples of studies and reports in the historic and current literature. Although there is no dispute that pollution can affect the health of aquatic organisms under laboratory conditions and may be responsible for the decline of populations of such animals in some inland waters and some estuaries, most of the evidence for pollution causing or increasing disease in fish in open waters is circumstantial. Historical data proves that almost all fish and shellfish diseases known today have been described since the end of the last century. However, it is also known that water pollution, especially in inland waters, has for the past 400-500 years been the result of urbanization and industrialization. This has resulted in some major rivers becoming devoid of or deficient in fish stocks. The concern that pollution may influence the health status of fish and shellfish stocks has increased over the past 20 years. Initial attention was paid to epidermal diseases, including fin-rot in demersal fish, and protozoan diseases in molluscs in the heavily polluted bays and estuaries in North America. As the interest in this subject spread, it became political, and often controversial, especially amongst the North Sea countries. The disagreements have largely been settled amongst scientists because international bodies, such as the International Council for Exploration of the Sea (ICES), established workshops to investigate sampling methods and disease-reporting techniques. Recommendations from those workshops have contributed to some form of standardization for field work and the subject, although largely subjective, has some objective approaches which are described. As there are variable, interacting biological and physical influences in the aquatic environment, it is difficult to establish the background prevalences of diseases in populations offish and shellfish. Examples of the influences of climatic changes are presented, and these show that short-term catastrophes can be directly related. However, a more long-term problem is water acidification resulting largely from anthropogenic activities. In parts of Scandinavia this has, and is, leading to decimation offish stocks in inland waters. In general, diseases in fish and shellfish are very localized, but there is concern amongst scientists that certain cancers, especially liver tumours, occurring in demersal fish inhabiting polluted estuarine and coastal waters, are related to the release of chemicals, e.g. hydrocarbons, pesticides and heavy metals. This subject is discussed in detail, with examples of the author's own studies in North Sea fish. It is concluded that cancers in fish are of extremely low prevalence, and only present in a very few species, and then only in the oldest animals. Though changes in disease pattern may well be an indication of adverse environmental effects, further research is necessary for conclusive evidence.

The fish production in aquaculture is growing from year to year. However capacities of current aquaculture facilities are limited. So the need of intensification of old facilities and building new intensive facilities is obvious. The high intensity of fish culture generates some questions. Could water reuse affect fish growth, welfare, health or quality of final product? A lot of research was performed for this issue but just a few works compared water reuse systems (RAS) versus flow thru systems (FTS). A problem with CO2 oversaturation was solved by shallow diffusers. Fin erosion seems to be a problem of high stocking density and system hygienic but it is not related directly to water reuse. A few papers were written about biochemical blood stress markers but it was mostly aimed to acute crowding or changes were found at extreme stocking densities over 124 kg.m3 for rainbow trout and 70 kg.m3 for sea bass. The fish are able to accustom to increased noise produced by RAS equipment very fast so it don’t affect fish negatively. There wasn’t found any prove of main water reuse to fish influence in the available literature. All results indicates that if the ecological parameters are kept in natural range for the fish reared in RAS, there is no negative effect of water reuse on fish.

Abstract Movement past hydroelectric dams and related in-river structures has important implications for habitat connectivity and population persistence in migratory fish. A major problem is that many of these structures lack effective fish passage facilities, which can fragment spawning and rearing areas and negatively impact recruitment. While traditional fish passage facilities (e.g., ladders, trap and haul) can effectively enable fish to pass over barriers, their capital or operational costs can be significant. We evaluated the utility of a novel transport device that utilizes a flexible tube with differential internal air pressure to pass fish around in-river barriers. We apportioned a total of 147 adult fall Chinook salmon (Oncorhynchus tshawytscha) nearing maturation to three treatments and a control group. In two of the treatments, adult fall Chinook salmon were transported through the device via two lengths of tube (12 or 77 m) and we compared their injury, stress, and immune system responses and reproductive function to a third treatment where fish were moved by a standard trap-and-haul method and also to a control group. We observed no significant differences among the treatment or control groups in posttreatment adult survival, injury, or stress. Indicators of immune system response and reproductive readiness were also not significantly different among the four groups. Egg survival was significantly different among the groups, with the highest survival in the eggs from females transported 77 m and lowest in the control group; the differences were highly variable within groups and not consistent with the duration of treatment or degree of handling. Taken together, the results suggest the device did not injure or alter normal physiological functioning of adult fall Chinook salmon nearing maturation and may provide an effective method for transporting such fish around in-river barriers during their spawning migration.

Full textAbstract:
The Swedish risk management case of Baltic fatty fishes, in which dioxin levels may be too high, is a typical multidimensional food safety decision problem involving public health, economic, environmental and socio-cultural aspects. To effectively address the dioxin food safety problem, the multiple dimensions and conflicting interests of stakeholders have to be considered systematically when evaluating competing risk management options. The objectives of this study were to illustrate the applicability of the Multi-Criteria Decision Analysis (MCDA) method for multidimensional food safety risk management problems, and to evaluate the Swedish dioxin risk management using MCDA. The results show that the MCDA method is indeed a relevant tool for modelling the multifactorial Swedish dioxin problem and for initiating discussions amongst stakeholders to increase the acceptance of chosen strategies. Abolishing the derogation from the European Commission’s maximum limits for the presence of dioxins in Swedish fish is the dominant strategy for risk assessors, whereas the preferences provided by the other stakeholders would suggest a continuation of the derogation without providing consumer information. However, the preferences of female consumers match with the 2011 decision of the Swedish government to ask for a derogation in combination with consumer information. The conclusion drawn from our MCDA analysis is comparable to the government’s decision that—given the gradual reduction in dioxin concentrations in Baltic fish—the decision to continue providing consumer information or not mainly depends on how risk managers balance the preferences of the different stakeholders.

ABSTRACT We studied 50 antimicrobial resistance mechanisms associated with Escherichia coli strains isolated from five species of commercial fish to evaluate the carriage and type of extended-spectrum β-lactamases (ESBLs) in these isolates. One hundred fifty samples of fresh raw fish were collected from large supermarkets and fish markets in northern Portugal during 2017. Thirty samples from each species were screened for the presence of E. coli and ESBL-producing E. coli. The samples were spread onto Levine plates with or without cefotaxime (2 μg/mL). The sensitivity of the isolates was determined for 16 antibiotics. The resistance and virulence genes were investigated by PCR. From the 150 samples, 45 E. coli isolates were recovered, and 3 of these isolates produced ESBL. All of these ESBL-producing isolates were resistant to β-lactams and harbored the blaCTX-M-1 and blaTEM genes, and all belonged to phylogenetic group A. One ESBL-producing E. coli isolate also was resistant to tetracycline and harbored the tet(A) gene, and another isolate was resistant to streptomycin and harbored the aadA gene. The remaining E. coli isolates were resistant to individual or combinations of the following antibiotics: tetracycline (16 isolates), sulfamethoxazole-trimethoprim (10 isolates), streptomycin (9 isolates), ampicillin (8 isolates), and chloramphenicol (2 isolates). The blaTEM, tet(A), aadA, and cmlA genes and combinations of sul genes were detected among most isolates that were resistant to ampicillin, tetracycline, streptomycin, chloramphenicol, and sulfamethoxazole-trimethoprim, respectively. The unmonitored and excessive use of antibiotics in aquatic environments promotes the development and propagation of antimicrobial resistance, and fish can be reservoirs of antibiotic resistance genes, which can easily be transmitted to humans through the consumption of raw fish, creating a public health problem.

Nutritional problems in Indonesia is still a serious health problem, especially of malnutrition and stunting. One of the efforts to improve the pattern of food consumption that aimed to overcome the malnutrition among the community, especially proteins, vitamins and minerals is by utilizing the tuna fish innards into fish meal innards in the form of biscuit. This study aims to know the acceptability and the shelf life of the biscuits with substitution of tuna fish innards. The method of research was pre experimental study with one shot group design. Acceptability was assessed by hedonic test among 35 panelists. Furthermore, the best formula was tested for critical moisture content to know it shelf life and the result was presented in tabular and narrative form. The results showed that the best panelist acceptance of biscuits with substitution of tuna starch ingredients was formula X02 (5% of tuna fish innards). In addition, there were about 54%, 66%, 77%, and 71% of panelist like the taste, scent, color and texture of the selected formula, respectively. The result of critical water content showed the biscuit has 48 days or 1,6 months of shelf life. For further study, it is suggested to make biscuits with 5% formula of tuna fish innards. Finally, various shelf life measurement might be consider.

Microbial metabolites have proven effects to inhibit food spoilage microbiota, without any development of antimicrobial resistance. This review provides a recent literature update on the preservative action of metabolites derived from microorganisms on seafood. Fish and fishery products are regarded as a myriad of nutrition, while being highly prone to spoilage. Several proven controversies (antimicrobial resistance and health issues) related to the use of synthetic preservatives have caused an imminent problem. The demand for minimally processed and naturally preserved clean-label fish and fishery products is on rise. Metabolites derived from microorganisms have exhibited diverse preservation capacities on fish and fishery products’ spoilage. Inclusions with other preservation techniques, such as hurdle technology, for the shelf-life extension of fish and fishery products are also summarized.

B chromosomes (B) are supernumerary, additional and non-homologous to standard (A) chromosomes. Significant biological questions concerning the origin and structural organization of Bs are under discussion. Previous reports found that B chromosomes are enriched with repetitive elements and can carry functional genes. The present study is aimed to extend our knowledge of the structure and composition of B chromosomes. We have combined cytogenetics and genomics approaches to undertsand the B chromosome problem. Cytogenetics analysis, applied to cichlid fish Astatotilapia latifasciata, revealed the presence of 1 or 2 B chromosomes. Next generation sequencing data analysis, based on differential coverage approach, among B- (individual without B) and B+ (individual with B) samples, detected a higher number of copies for the Indian Hedgehog b (Ihhb) gene and 45S RNA transcriptional gene-cluster. Fluorescence in situ hybridization (FISH) confirmed that these genes are located on the B chromosome. In addition, the excessively abundant and strong signals of IHHB on B shows that this gene has accumulated and amplified its copies due to frequent duplication events. The findings also demonstrate that B chromosome have incorporated the entire 45S RNA cluster (18S ribosomal RNA, internal transcribed spacer 1, 5.8S ribosomal RNA, internal transcribed spacer 2, and 28S ribosomal RNA) from the A complement set. Our study contributes to explain that these genic sequences are vital components in constitution of B chromosomes.

Background: Liver fluke disease caused by Opisthorchis viverrini remains a major public health problem with its crucial risk factors caused by some individual habits or false beliefs among the people in northeastern Thailand concerning the consumption of raw fish meat dishes. Objectives: This study explores the predictive risk factors for the infection of liver fluke disease. Methods: The sample consisted of 400 people aged 30 years and above in Thanya sub-district, Kamalasai district, Kalasin province. A cross-sectional analytic study, using the χ2 test, odds ratio and 95% confidence interval, was used to find the influence of each variable, along with the use of multiple logistic regression (p = 0.05). A questionnaire form was used as the research instrument. Results: Factors found in the results are as follows: households with a cat were 7.00 times more at risk than households without a cat; eating raw fish dishes prepared by themselves increases the risk of infection by 2.58 times; eating raw fish dishes prepared by family members increases the risk by 4.74 times; and raw fish dishes bought from a community market increases the risk by 2.33 times. Conclusion: A campaign should be launched to educate people not to eat raw or undercooked fish dishes, but to fully cook fish dishes before eating, as the food is still delicious, but also safe, healthy, and free from liver fluke infection.

Full textAbstract:
In recent years, plastic waste has become a universally significant environmental problem. Ingestion of food and water contaminated with microplastics is the main route of human exposure. Fishery products are an important source of microplastics in the human diet. Once ingested, microplastics reach the gastrointestinal tract and can be absorbed causing oxidative stress, cytotoxicity, and translocation to other tissues. Furthermore, microplastics can release chemical substances (organic and inorganic) present in their matrix or previously absorbed from the environment and act as carriers of microorganisms. Additives present in microplastics such as polybrominated diphenyl ethers (PBDE), bisphenol A (BPA), nonylphenol (NP), octylphenol (OP), and potentially toxic elements can be harmful for humans. However, to date, the data we have are not sufficient to perform a reliable assessment of the risks to human health. Further studies on the toxicokinetics and toxicity of microplastics in humans are needed.

AbstractAt the beginning of the new millennium, helminth infections continue to be prevalent, particularly among impoverished populations. This study attempts to create the first health informatics model of helminthiasis in Thailand. The authors investigate how a health informatics model could be used to predict the control and eradication in a national control campaign. Fish-borne helminthiasis caused by Opisthorchis viverrini remains a major public health problem in many parts of South-East Asia, including Thailand, Lao PDR, Vietnam and Cambodia. The epicentre of this disease is located in north-east Thailand, where high prevalence coexists with a high incidence of cholangiocarcinoma (CHCA). The current report was conducted to determine a mathematical model of surveillance for helminthiasis while also using a geographic information system. The fish-borne helminthiasis model or the predicted equation was Y1 = 3.028 + 0.020 (elevation) – 2.098 (clay). For soil-transmitted helminthiasis, the mathematical model or the predicted equation was Y2 = −1.559 + 0.005 (rainfall) + 0.004 (elevation) − 2.198 (clay). The Ministry of Public Health has concluded that mass treatment for helminthiasis in the Thai population, targeting high-risk individuals, may be a cost-effective way to allocate limited funds. This type of approach, as well as further study on the correlation of clinical symptoms with environmental and geographic information, may offer a novel strategy to the helminth crisis.

A Review with A Focus on Effects on Fish Health and Predictive Traits of MPs Ingestion." Water 13, no. 16 (August 14, 2021): 2214. http://dx.doi.org/10.3390/w13162214.
Full textAbstract:
Microplastics (MPs) have received increasing attention in the last decade and are now considered among the most concerning emerging pollutants in natural environments. Here, the current knowledge on microplastic ingestion by wild freshwater fish is reviewed with a focus on the identification of possible factors leading to the ingestion of MPs and the consequences on fish health. Within the literature, 257 species of freshwater fishes from 32 countries have been documented to ingest MPs. MPs ingestion was found to increase with rising level of urbanization, although a direct correlation with MPs concentration in the surrounding water has not been identified. MPs ingestion was detected in all the published articles, with MPs presence in more than 50% of the specimens analyzed in one study out of two. Together with the digestive tract, MPs were also found in the gills, and there is evidence that MPs can translocate to different tissues of the organism. Strong evidence, therefore, exists that MPs may represent a serious risk for ecosystems, and are a direct danger for human health. Moreover, toxicological effects have also been highlighted in wild catches, demonstrating the importance of this problem and suggesting the need for laboratory experiments more representative of the environmental situation.

Full textAbstract:
Rising prices of traditional feedstock for feed preparation (fish meal and oil) is a problem for aquaculture enterprises. Their replacement with inexpensive components of vegetable origin is the way for solving the problem. The aim of the study is to generalize and analyze scientific data on using new types of vegetable feedstock in aquaculture feeds, on technologies of their preparation and use, influence on feed quality. Selection and systematic review of scientific literature on the topic of the study for the period of 2017-2022 has been carried out. The derivatives of land agricultural plant products such as oilseed meal, protein concentrates, gluten and food industry wastes are the main types of vegetable feedstock for feed preparation in aquaculture. Currently, vegetable oils are the best variants for replacing fish oil in fish diets. Partial or complete replacement of fishmeal and oil with new types of vegetable feedstock is possible and does not lead to deterioration of fish health and growth rate when these components are included in the diet at recommended doses. Such a replacement is economically advantageous. But there are negative effects in the use of vegetable feedstock, such as the presence of anti-nutritional factors that limit its use in aquaculture. The development of recipes of cost-effective fish feeds in which fish meal and oil are completely replaced by vegetable components is a research priority for the development of intensive aquaculture.

Full textAbstract:
Fish diseases are often caused either by bacteria, viruses, fungi, parasites, or a combination of these pathogens. Of these, bacterial fish diseases are considered to be a major problem in the aquaculture industry. Hence, the prevention of such diseases by proper vaccination is one of the integral strategies in fish health management, aimed at reducing the fish mortality rate in the aquaculture farms. Vaccination offers an effective yet low-cost solution to combat the risk of disease in fish farming. An appropriate vaccination regime to prevent bacterial diseases offers a solution against the harmful effects of antibiotic applications. This review discusses the role of live-attenuated vaccine in controlling bacterial diseases and the development of such vaccines and their vaccination strategy. The current achievements and potential applications of live-attenuated and combined vaccines are also highlighted. Vaccine development is concluded to be a demanding process, as it must satisfy the requirements of the aquaculture industry.

Full textAbstract:
Abstract When treating large burns, autologous skin availability becomes a problem and burn surgeons rely heavily on allogenic and xenogeneic skin for temporary coverage after excision. Application of cadaveric and pig skin grafts carries a risk of auto-immune response and risk of viral and bacterial diseases transmission, and there are many cultural and religious rejections for use of porcine grafts. There has recently become available an alternative resource of xenograft using acellular fish skin (KerecisTM Omega3 Burn). This has been described as providing an effective, safe, efficient skin substitute, free of the risk of transmission of viral disease, and auto-immune reaction risk. Methods Ten patients having split-thickness skin grafting for burn injury were treated with the fish skin xenografts. Results There were no adverse reactions noted on the use of the fish skin grafts. No patient had any reaction to the fish skin and there was a zero incidence of infection. The handling of the fish skin was excellent, a robust and pliable xenograft that was easy to apply. The quality of donor site healing was judged to be good in all cases. Both the analgesic effect noted and the relatively short average times until 100% re-epithelialization are promising. We also illustrate two cases where the dressing was used to treat superficial burns.

In this paper, we dealt with the problem of the rejections of fishery products exported to other countries via Morocco and their economic impact. The study was conducted using a survey by exporters of the fishing industry. The analysis of data shows that backflows can be caused by different sanitary or documentary reasons. Also, the health profile for the main species can be assessed by a criticality matrix "fish species: hazard: commodity". The determinants of the rejections of exported fish products were analyzed by a multiple regression. This econometric technique is considered valuable in our study to evaluate the impact of a set of variables on the cost of the rejections of fishery products. The rejections of fishery products have a tremendous impact both on fish business operators as well as for the competent authorities. Hence, there is the need to control the various health hazards associated with fishery products by professionals. This was done by adopting plans for health control within their establishments and for the strengthening of official control by the competent authority in a coregulation framework.

Introduction: Based on the Kab. Bogor, Shows that the first top infectious disease in the hospital is Non-Specific Acute Respiratory Infection with a total of 1,436,388 (15.98%), then the second is acute nasopharynx with a total of 1,235,732 (13.75%), and so on followed by other diseases. Based on the results of the above observations, the most influential and possible wide impact on public health is the condition of sanitation and environmental health, namely the problem of household waste. Objectives: The purpose of knowing the results of risk factor analysis with the incidence of acute respiratory infections (ARI) then identifying and prioritizing health problems/implementation achievements and knowing alternative solutions to health problems/achievements of implementing health programs in Bogor Regency in 2020. Method: Descriptive analytic with a population of 19 people Information and data in this study were obtained through field observations, interviews, literature studies to data collection using google form media. The data obtained were then analyzed using the Criteria Matrix Technique (Criteria Matrix Technique) and Ichikawa Diagrams (Fish Bones). Result: Based on the results of the study, there were 4 priority problems, namely it was known that the frequency of littering and burning garbage was 14.4% the frequency of smoking habits in the house was 12.8%. healthy, namely 8.4%, the frequency of air conditions around the house worsening due to pollution is 6.0%. Conclusion: The behavior of littering and the habit of processing waste by burning are problems that we found while observing the environment in the Bogor Regency area, this was due to a lack of knowledge and public awareness about proper and proper waste management. That way, the alternative problem solving that researchers want to do is to run the program "Ready to Prevent ARI with T2M2S (No Burning and Disposing of Garbage Carelessly)".

AbstractObjectiveTo build a comprehensive overview of the potential role of fish in improving nutrition with respect to certain micronutrient deficiencies in developing countries.DesignA comprehensive literature review was completed. For this the electronic library databases ASFA, CABD and Scopus were systematically searched and relevant references cited in these sources were carefully analysed. The search terms used were ‘fish’, ‘small fish species’, ‘micronutrients’, ‘food-based strategies’, ‘fish consumption’ and ‘developing countries’. The quality of data on nutritional analyses was carefully reviewed and data that lacked proper information on methods, units and samples were excluded.ResultsThe evidence collected confirmed the high levels of vitamin A, Fe and Zn in some of the small fish species in developing countries. These small fish are reported to be more affordable and accessible than the larger fish and other usual animal-source foods and vegetables. Evidence suggests that these locally available small fish have considerable potential as cost-effective food-based strategies to enhance micronutrient intakes or as a complementary food for undernourished children. However, the present review shows that only a few studies have been able to rigorously assess the impact of fish consumption on improved nutritional status in developing countries.ConclusionsFurther research is required in areas such as determination of fish consumption patterns of poor households, the nutritional value of local fish and other aquatic animals and the impact of fish intake on improved nutritional status in developing countries where undernutrition is a major public health problem.
