Fingerling largemouth bass (Micropterus salmoides), 20 mm total length, readily accepted carp eggs and reached a length of 43 mm in 25 days at a water temperature of 27°C. Survival was 52%. Carp eggs were more acceptable than moist feed to largemouth bass fingerlings 43 to 50 mm long. An average of 49% of the fish that refused to accept moist feed during the first training period accepted carp eggs and later accepted moist feed. Training success was greatest at the highest water temperature considered.
