Abstract Thirteen diets were offered to largemouth bass (Micropterus salmoides) fry (10 mm long and larger) for nine or more days. Survival was used as an indication of feed acceptance. Whole eggs of common carp (Cyprinus carpio) were used as the control diet. Five prepared diets contained from 10 to 97% carp eggs. Seven other diets contained a variety of ingredients and were of various feed types: dry pellets, semimoist pellets, moist pellets, and flakes.

The only other diet that resulted in more than 4% survival was a commercially available flaked fish food (18% survival). Maturity of carp eggs did not affect acceptance by fry. Largemouth bass fry exhibited no noticeable attraction to the wa...
