A 3×3 factorial experiment was conducted in flow-through aquaria to evaluate effects of diets, containing 0%, 4%, or 8% menhaden fish meal, on growth performance, body composition, and insulin-like growth factor-I (IGF-I) of juvenile channel catfish of Mississippi “normal” (MN), NWAC103 [formally known as USDA103], or USDA303 strains. Twenty fish with an average weight of 4.7±0.1 g fish (±S.D.)...

an experiment was conducted to determine apparent ileal digestibility of crude protein (cp) and amino acids (aa) and digestible cp and aa of fish meal (fm) in 21-d-old broiler chickens using the regression technique. four diets containing 0, 1, 2, and 3% fm in place of cornstarch were formulated with fm as the sole contributor of cp and aas in the sequential diets. eighty 14-d-old broiler chick...

This study was carried out to measure the prececal protein and ether extract digestibility of shrimp and fish meal using the regression approach. A total of 280 Cobb 500 day-old broilers (mixed sexes) were randomly allotted to 7 treatment groups (4 replicates of 10 broilers each) in a completely randomized design. Feed intake was higher in the birds that received protease-supplemented shrimp me...

Costs of compounded diets containing fish meal as a primary protein source can be expected to rise as fish meal prices increase in response to static supply and growing demand. Alternatives to fish meal are needed to reduce production costs in many aquaculture enterprises. Some plant proteins are potential replacements for fish meal because of their amino acid composition, lower cost and wide a...

—Taurine has been demonstrated to be conditionally indispensable for several carnivorous fish species. Current trends in trout production include decreasing levels of fish-meal content in feeds, along with faster growing strains of fish. Taurine may be a limiting nutrient in support of elevated planes of growth for rainbow trout. A 9-wk feeding trial was conducted using a factorial treatment de...

Three feeding trials were conducted to evaluate low-gossypol cottonseed flour as a replacement for fish meal in the diet of black sea bass and southern flounder raised in RAS. In experiment 1, diets were formulated to replace 0, 50, 75 and 100% menhaden fish meal protein (FMP) by glandless cottonseed flour protein (GCP) and solvent-extracted cottonseed flour protein (SCP), and to replace 100% F...
