—Channel catfish Ictalurus punctatus do not feed well at low temperatures. It is generally thought that a diet containing fish meal enhances feed palatability at low temperatures since fish meal is highly palatable to fish. There is a lack of information on the effects of fish meal levels on the growth performance of channel catfish reared at low temperatures. Therefore, a study was conducted i...

Ž . The use of a co-extruded soybean poultry by-product meal CEPM and flashed dried poultry Ž . by-product meal FD-PBM was evaluated as replacements for fish meal in a practical diet formulated to contain 32% crude protein and 8% lipid. Each meal was substituted for menhaden Ž fish meal on an iso-nitrogenous basis and offered to juvenile Litopenaeus Õannamei mean initial . Ž wt."S.D., 0.37"0.01...

The influence of replacing diet fish meal LT94 (FM) with different levels of full fat soybean meal (FFSB) on growth performance and enzymes activity in stomach, hepato-pancreas and intestine were investigated for Nile tilapia Oreochromis niloticus. Four diets (D1, D2, D3 and D4) were formulated 0, 15, 20, and 20 g/100 protein of diets + DL-methionine by replacing FFSB with fish meal respectivel...

Fish inhabiting polluted waters accumulate various metals in tissues. The transfer of these into human beings through the food chain has adverse effects. The present study was undertaken to elicit the effect of consumption of contaminated fish meal on the hematological parameters of albino rats, Rattus norvegicus (Album). Thirty rats, weighing 45-50gms and randomly divided into 5 groups (n=6), ...

Fish consumption is associated with both health benefits from high-quality proteins, minerals, vitamins, and fatty acids and risks from contaminants in fish. Fish consumption advisories are issued by many government agencies to keep exposure to contaminants at a safe level. Such advisories are typically based on fillets and neglect consumption of other fish parts such as eggs by certain subpopu...

Production of crystalline l-Thr results in the generation of a Thr biomass that contains more than 80% CP, 5.20% Lys, 5.10% Val, 4.52% Thr, 4.15% Ile, and 1.06% Trp. This Thr biomass product can possibly be used as a feed ingredient in diets fed to weanling pigs, but there is little information about the nutritional value of this product. The objective of this work was to determine the AA diges...

Our study was focused on characterization of dominant Bacillus bacteria isolated from the digestive tract of Oncorhynchus mykiss. After 8 weeks, the fish fed with probiotic-free diet were dissected under strictly controlled conditions. Fish intestines were eviscerated and its content diluted to 10−4 using Ringer solution. Two isolated bacteria were Gram-positive, catalase-positive, and oxidase-...

An eight week feeding trial was conducted to evaluate the potential of Gliricidia maculata leaf meal as dietary protein source in the diet of Cirrhinus mrigala fingerlings. Four experimental diets were formulated to contain 20%, 30%, 40% and 50% G. maculata leaf meal (Diets 1 – 4) to partially replace other protein ingredients in the C. mrigala diet. The diet containing 0% leaf meal served as t...

Abstract This study aimed to determine the effect of using fermented shrimp shell meal in feed on growth Asian sea bass. was designed with a completely randomized design (CRD) 4 treatments and 3 replications thus treatment obtained A (feed without meal); B (Feed 15% C 20% meal) D 25% meal). Parameters observed were daily rate survival. The results showed that percentage substitution fish ration...
