Niacin requirement for optimum growth, feed conversion and protection of rainbow trout, Salmo gairdneri Richardson, from ultraviolet-B irradiation
Triplicate groups of 75 rainbow trout, Salmo gairdneri Richardson, (mean weight 0–76 g) were fed a semipurified diet containing added niacinamide in amounts of 0.0, 1.25, 2.5. 5, 10, 20, 40, 80 or 160 mg/kg diet (ppm), for 16 weeks to determine the amount of niacinamide needed for optimum growth, feed conversion, and prevention of dermatopathy induced by UV light. At the end of the study, fish wer

Effects of cumulative loading level, as fish weight per unit flow, on water quality and growth of lake trout
Lake trout, Salvelinus namaycush, were cultured in a series of five rearing units (in triplicate). The fish removed available oxygen in each unit, from about 10.5 to 7.0 mg/L. Oxygen was replaced, through aeration, between rearing units. Effects of cumulative loading, as fish weight/flow rate, are described in terms of water quality and fish growth. In fish reared at the highest loading level, mea

Evaluation of glutamic acid and glycine as sources of nonessential amino acids for lake trout (Salvelinus namaycush) and rainbow trout (Salmo gairdnerii)
1. A semi-purified test diet which contained either glutamic acid or glycine as the major source of nonessential amino acids (NEAA) was fed to lake and rainbow trout.2. Trout fed the diet containing glutamic acid consistently showed better growth and feed conversion efficiencies than those fed the diets containing glycine.3. The data indicate that these trout utilize glutamic acid more efficiently
