Fish diseases are one of the major problems in fresh water biota. There is an urgent need in aquaculture to develop microbial control strategies, since diseases epidemics are recognized as important constraints to aquaculture production, trade and the development of antibiotic resistance has become a matter of growing concern. In this study, we evaluated the tilapia fish (Oreochromis mossambicu...

physicochemical properties of surimi and kamaboko obtained of solubility in acid, alkaline and conventional methods were compared. the results indicated that the highest protein recovery was related to solubility in acid, alkaline and conventional methods, respectively. the highest removal of lipid and myoglobin was observed by solubility in alkali. excretion of total pigment and sulfhydryl gro...

Herring (Clupea harengus) contain valuable proteins but is difficult to process into high-quality foods due to its small size and high content of bones, heme-proteins and lipids. Herring is among the most abundant fish species in the world, but is currently utilized largely for fish meal and oil production. The work presented in this thesis has aimed at evaluating pH-shift processing as a metho...

The aim of this study was to evaluate the effect of alkaline and NaCl on functional properties of protein isolated from Lanternfish (Benthosema pterotum). In this study, extraction of fish protein was performed at different concentrations of NaCl (0.5%, 1.5%, 3% and 4.5%) at pHs 10 and 12. The results showed alkaline treatment improved the functional properties and the recovery yield of protein...

a series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. in experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. weight gain of fish was prop...

A vibrio isolated from the intestine of a coastal fish was identified as Vibrio hollisae by its biochemical characteristics. The isolate reacted with the gene probe for the thermostable direct hemolysin of Vibrio parahaemolyticus. The hemolysin produced by the isolate from the fish had traits identical to those of the thermostable direct hemolysin-like hemolysin produced by a clinical strain of...

Background Athletes have a choice of different animal (e.g. whey, casein, egg, beef, fish) or plant protein (e.g. soy, rice, pea, hemp) sources, which differ in numerous ways such as the presence of allergens (lactose, soy), cholesterol, saturated fats, digestion rate (fast, intermediate, or slow absorption of amino acids), or the relative amount of individual amino acids. While digestibility o...

Fish is a vital food source for people and contributes about 60% of the world's supply protein. It extremely perishable, if not properly preserved, it deteriorates can be detrimental to human health when consumed. The present study was carried out isolate Staphylococcus aureus Shigella spp. from thawed fish. A total 10 fish samples were bought different retailers in markets within Enugu metropo...

Streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. Capsular polysaccharide (CPS) of S. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of S. iniae infection in aquatic animals. The CpsD gene was determined to be highly conservative in capsule polysaccharide operon. Prokaryotic expression of t...
