Abstract: Three experimental groups with different feeding frequencies, different feeding rates and compensation feeding were set up to study their effects on the growth of Micropterus salmoides. The results showed that different feeding rates of 2%, 3% and 4% had no significant effect on the growth of Micropterus salmoides. Before the individual weight of 50 g, the feeding rate was 4%, and it gradually decreased to 2% in the later period. Under the condition that the feeding rate was relatively fixed, different feeding frequencies would have an impact on the growth of Micropterus salmoides. Under the conditions of suitable water temperature, it was reasonable to feed twice a day. The experimental fish fed for 5 days and then deprived of feed for 1 day showed fully compensated growth, and there was no significant difference in weight gain rate, daily weight gain and specific growth rate compared with the continuous feeding group (P>0.05). Therefore, according to the feeding conditions of fish in the breeding process, stopping feeding for 1 day every 5 days could save feed and labor and improve breeding efficiency.

Key words: Micropterus salmoides, feeding rate, feeding frequency, compensating feeding
