Abstract：A multi-cycle recovery growth experiment was carried out to determine the effects of different feeding models on the growth of Epinephelus fuscoguttatus (♀) × E.lanceolatus (♂) and water quality.Four treatments were set in the experiment, which included (S1 R3) fish were starved for 1 day and then were fed to satiation for 3 days; (S1 R7) fish were starved for 1 day and then were fed to satiation for 7 days; (S1 R11) fish were starved for 1 day and then were fed to satiation for 11 days;and (C, the control) fish were fed to satiation during the whole experimental period.The results indicated that the weight gain rate and the SGR of the fish in S1 R7 and S1 R11 were similar to those of C (P＞0.05) ;the weight gain rate and the SGR of the fish in S1 R3 was significantly lower than that in C (P＜0.05) ;the feed coefficient was similar between S1 R11, S1 R7 and C, but the feed coefficient of S1 R3 is significantly lower than that of C;and as a whole, the water quality index of S1 R3 and S1 R7 was superior to that of C, but that of S1 R11 was similar to that of C.Considering the results of growth and water quality, suitable feeding model did not impact on the normal growth of Epinephelus fuscoguttatus (♀) ×E.lanceolatus (♂) .When the fish was starved for 1 day and then were fed to satiation for 7 days, the growth of the fish was similar to that of fish fed to satiation every day, but the water quality was apparently superior.Our findings advanced a solution for the industrial fish farming and raised the management level.
