Fillet texture plays a significant role in consumer acceptance, which heavily influenced by exercise according to previous studies. “Xianfeng No. 2”, novel hybrid of Megalobrama amblycephala ( M. ) (♀) and Ancherythroculter nigrocauda A. (♂), with characteristics quick growth, good disease resistance, anti-stress capability, is one an important aquaculture fish species China, however, the ways ...

As concerns mount over the human health risks associated with consumption of fish contaminated with persistent organic pollutants, there exists a need to better evaluate fish body burdens without lethally sampling many of the important commercial and sport species of interest. The aim of this study was to investigate two novel methods for estimating organic contaminants in fish that are a conce...

This study was conducted to investigate the effect of cyanide on pattern rhodanese activity distribution in selected organs Coptodon zillii and water quality Igun reservoir. Fish samples were collected monthly for period a year cover both seasons. The physical parameters such as air temperature, conductivity, TDS, pH, depth, transparency determined. Air temperature determined situ with mercury-...

Gamma tocopherol (gT) exhibits beneficial cardiovascular effects partly due to its anti-inflammatory activity. Important sources of gT are vegetable oils. However, little is known to what extent gT can be transferred into marine animal species such as Atlantic salmon by feeding. Therefore, in this study we have investigated the transfer of dietary gT into salmon. To this end, fish were fed a di...

Tank color impacts marine fish larval performance, as dark tanks appear to provide contrast that allows larvae to better visualize live and artificial prey. While tanks can be fabricated in any color, commercially available on–growing systems are generally black, green, or dark and light blue. Anecdotal information suggested that certain juvenile fish perform better in tanks with black sides an...

This study describes the variability of important quality traits in gilthead sea bream produced under intensive conditions in Southern Europe and purchased in a French market (Nantes). Chemical, sensory and histological characteristics were performed on 18 samples delivered over a year. All fish presented far lower dioxin and DL-PCBs or heavy metals concentrations than the maximum limit level s...

An initial investigation into the inclusion of high protein distillers dried grain with solubles (HPDDG) in juvenile rainbow trout Oncorhynchus mykiss diets was conducted during a 36-day feeding trial. Four experimental diets containing either 10% or 20% HPDDG with supplemental amino acids, and either with or without phytase, were compared to a fish-meal-based, non-HPDDG, diet. There was no sig...

As nutrition-related expenses constitute the majority of the costs for aquaculture farms, it is essential for them to use feeds that provide an ideal combination of nutrients for the species of choice. In this study, the relative effect of consuming three different pelleted feeds (B, C and D) in comparison to frozen baitfish (A; control) were compared on juvenile Asian seabass (77.3 ± 22.4g) th...

There is a large body of evidence that n-3 fatty acids, especially EPA and DHA are beneficial for human health. Content of these fatty acids in fish fillet can be influenced by several factors. This thesis examined differences in lipid content, lipid class and fatty acid composition among three parts of common carp fillets. The effect of genetic background on lipid content and fatty acid compos...
