Evaluation of Five Commercially Prepared Diets for Striped Bass

Abstract
Fingerling striped bass (Morone saxatilis) were held in tanks at 20°C and fed five commercially prepared diets over an 8-week period. There were no significant differences in weight gain among fish fed a commercial trout diet (daily gain, 1.49% of body weight), the U.S. Fish and Wildlife Service open-formula trout diet GR-6-30 (1.76%/d), or the Service's Atlantic salmon diet ASD-2-30 (1.72%/d). Striped bass fed a modified catfish diet had significantly lower growth (0.74%/ d) than those fed the trout or salmon diets. Striped bass fed a commercial diet consisting of all fish by-products gained only 0.09% body weight!d after losing weight during the first 2 weeks. Fingerling and yearling striped bass reared in ponds grew significantly faster when fed a commercial trout diet than when fed a modified catfish diet.
