Pampus Argenteus

The effects of different processing methods (Frying cooking, brining and boiling) on the proximate composition of fish species (Pampus argenteus) were investigated. The objective of this work is to know the best processing methods, the effect of processing on nutritional values of fish products. The result of the proximate composition of the fish species showed that the highest protein content (38.17%) was in P. argenteus processed with the frying process. The result of moisture content indicated that boiled samples were consistently the least (25.20%) while for fried sample had the highest moisture percentage. The lipid was reduced to the least value of 9.94% in the brined fish. In cooking, the important factors for consideration are moisture, lipids, and protein, though low moisture would ensure a fish product with extended shelf life. To have a longer shelf life, high protein is desirable, a low lipid is equally desirable as to reduce oxidation and rancidity in the samples which causes off-flavor and bad taste in fish products. In conclusion, all the processing methods are good and could extend the shelf life of the products with an exception of boiling method; they could keep the fish fillet free from spoilage and microorganisms attack for some period. This study showed that the proximate values obtained could be of help in choosing fish based on nutritional values.

ABSTRACTRoasted fish fillet is a popular snack food in the People's Republic of China, and the market appeal can be reflected by the high price, which exceeds 330 RMB/kg in some cases. However, the labeled fish common name generally cannot be connected with a particular species, and the processing treatments make it a challenging task to identify fish species based on morphological characteristics. This study used full DNA barcoding and mini-DNA barcoding for species identification of 202 specimens sorted from 64 roasted fish fillet products sold across China, which belonged to 32 distinct brands and claimed 16 fish common names on the label. Given the absence of a harmonization in defining these common names in China, scientific literature and the Latin-Chinese dictionary of fish names (http://fishdb.sinica.edu.tw/) were consulted to define at least the family for each common name, and an identified species outside the expected family was determined to be mislabeled. Results highlighted a high mislabeling rate of 75.5%. Even worse, fish species were identified as belonging to multiple families, not only from several products of the same brand under the same common name but also from several specimens sorted from the same product. Moreover, a health issue was highlighted by the identification of toxic Tetraodontidae species from one product. To protect the consumers from economic loss and even health risks, we recommended amendments to existing legislation and the compilation of a list of acceptable market names for fish species in China. Meanwhile, DNA barcoding is a powerful tool in fish forensics, and we recommended the use of this technique to assure the accurate species labeling of fish products.HIGHLIGHTS

Protein, lipid, ash and moisture content in the body muscles of two commonly available puffer fish species in Bangladesh (Leiodon cutcutia and Dichtomyctere fluviatilis) have been analysed from January 2018 to June, 2018. The puffer fish species were collected from different habitats i.e., Leiodon cutcutia from freshwater and Dichtomyctere fluviatilis from estuarine water. The percentage of the proximate composition varied in different months in both the species. In Leiodon cutcutia, moisture content fluctuated from 79.32% to 87.61% with an average of 83.75%; protein content from 6.35% to 13.31% with an average of 9.49%; lipid content from 1.57% to 2.32% with an average of 1.92% and ash content from 2.30% to 3.27% with an average of 2.84%. In Dichotomyctere fluviatilis, moisture content fluctuated from 73.77% to 84.18% with an average of 77.49%; protein content from 10.03% to 19.77% with an average of 16.80%; lipid content from 0.92% to 1.71% with an average of 1.32% and ash content from 2.77% to 3.34% with an average of 3.05%. The comparative evaluation of the nutritional value of the studied fish species revealed that the puffer fish from estuarine environment might contain higher amount of nutrients. Thus, proper utilization of this species towards sustainable management, nutritional composition and biosecurity issues will lead to achieve sustainable blue economy. Jahangirnagar University J.

The study was designed to investigate the effects of freezing periods and the combination of packaging with or without turmeric on the proximate composition of whole and sliced Labeo bata. The samples were subjected to 28 days of frozen (-20 °C) storage periods and analyzed for proximate composition such as moisture, protein, lipid and ash at intervals of 0, 14 and 28 days. Data obtained was subjected to analysis of variance (ANOVA) at 95% significant level. Different preservation periods and methods significantly affected the nutritional composition of fresh fish. Moisture, protein, lipid and ash content decreased with increasing storage periods when compared to the fresh fish as control. The highest percentage of protein was found in turmeric-treated whole fish preserved in polythene, C4, after the 14th (15.70±0.14) and 28th (15.27±0.21) day. On the other hand, the lowest percentage (14.01±0.10 and 13.22±0.18 for the 14th and 28th day, respectively) was found in sliced fish preserved without polythene, C5. In conclusion, the turmeric-treated whole fish preserved in polythene retained fish nutrients and ensured its good quality and composition longer than other treatments, thereby extending the shelf life during frozen storage.

Fish is a food that is consumed by many people because fish contain high nutrition. Fillet products are diversification of fishery products that are quite popular with the community. That is because fillet products are easy to consume and have good nutritional content. However, fish fillet products are easily degraded during transportation. So that triggers traders to use hazardous materials in the form of formalin to increase the shelf life of fillet products. The shelf life of fish fillet products needs to be improved in order to obtain good quality and not be easily damaged by storing fillets at low temperatures and the addition of active ingredients in the form of honey. Honey also has antimicrobial properties so that it can be used as a food preservative. Honey can inhibit the growth of bacteria that cause decay. The purpose of this study was to determine the effect of adding honey with different concentrations on the shelf life of white pomfret (Pampus argenteus) fillets at cold temperatures. This research was experimental by making honey solutions with different concentrations (0%: 10%; 11%). This research uses a completely randomized design (CRD). The shelf life test is done by calculating the value of TPC, Protein, pH, Tvbn, and organoleptic. TPC, Protein, pH, TVBN, and organoleptic test results showed that the addition of honey with different concentrations had a significant effect on the shelf life of white pomfret fish fillets. The best concentration of adding honey is at a concentration of 5%. While the shelf life that can be accepted by consumers can reach 6 days shelf life. The results showed that honey can be used as an alternative preservative in fish fillet meat that functions as an antimicrobial and fat oxidation prevention.

Consumer is very careful about healthiness; in this context nutritionists often highlight the importance of fish for human nutrition because of their protein and fatty acid composition. In order to stimulate utilisation and consumption of fish species by unusual target groups such as children, the aim of this research was to formulate and to evaluate shelf-life and nutritional values of fish preparations stored in modified atmosphere packaging (MAP). Fish species used for trail were <em>Trachurus trachurus</em> and <em>Oncorhynchus mykiss</em> fished and farmed in Basilicata region respectively. Fish burgers were made with different ingredients of plant and animal origin and packed in air (control) and in MAP and stored at refrigeration atemperature. Sensory, physicalchemical analysis as pH, a<sub>w</sub>, total volatile nitrogen (TVN), trimetilammine (TMA), thiobarbituric acid (TBA), free fatty acids (FFA) and microbiological analysis like aerobic plate count, Enterobacteriaceae, <em>Escherichia coli</em>, <em>Pseudomonas</em> spp., sulphite-reducing clostridia, <em>Staphylococci</em>, <em>Salmonella</em> spp. and <em>Listeria monocytogenes</em> were performed at intervals of 0°, 1°, 2°, 5°, 8°, 15°, 22°, day from production. Results showed that fish burgers stored in MAP had a longer shelf-life; protein degradation indexes and spoilage bacterial species showed lower values in the samples packaged in MAP compared with the control. The formulation of the fish burger meets the approval of the target consumers. The mixing of natural ingredients has made possible both the enhancement of the organoleptic characteristics with an excellent balance of nutritional values. The diversification of fish preparations, besides enhancing the fish production of marginal areas would add value to a product with potential and remarkable profit margins.

Seafood products are important sources of protein and components of a healthy and sustainable diet. Understanding consumers’ preferences for fish products is crucial for increasing fish consumption. This article reports the consumer preferences and willingness to pay (WTP) for different fish species and attributes on representative samples in five European countries (n = 2509): France, Germany, Italy, Spain, and the UK. Consumer choices were investigated for fresh fish in a retail market under hypothetical situations arranged by a labelled choice experiment conducted for seven fish species: Cod, herring, seabass, seabream, salmon, trout, and pangasius. The results show the highest premiums for wild-caught fish than farm-raised alternatives. Ready-to-cook products are generally preferred to whole fish, whereas fish fillet preference is more species-specific. The results show positive premiums for a sustainability label and nutrition and health claims, with high heterogeneity across countries and species. With consumers’ preferences and WTP being largely country- and fish-dependent, businesses (fish companies, retailers, and others) should consider the specific market context and adapt their labelling strategies accordingly. Public authorities campaigns should inform consumers about the tangible benefits related with health and environmental labels.

Aquaculture Industry

Abstract Aquaculture is currently one of the most rapidly growing food production industries in the world. The increasing global importance for this industry stems primarily from the fact that it is reducing the gap between the supply and demand for fish products. Commercial aquaculture contributes significantly to the economies of many countries since high-value fish species are a major source of foreign exchange. This review looks at the aquaculture industry, the issues raised by the production of fish through aquaculture for food security, the sustainability of the practice to agriculture, what the future holds for the industry in the next 10-20 years, and why there is a need to have available analytical procedures to regulate the safe use of chemicals and veterinary drugs in aquaculture.
