Abstract：This study used Sebastes schlegelii as the study subject and investigated the effects of adding different levels of sodium acetate to the feed on the growth performance of S ，schlegelii. Six groups of feed with equal nitrogen and lipid content were prepared，with sodium acetate added at the folowing levels：SAl 0 （omg/kg ，control），SA2（ 250mg/kg， ，SA3（ 500mg/kg ，SA4（ 1000mg/kg ），SA5 2000mg/kg） ！ and SA6 （4000mg/kg） .A total of 180 fish with an initial weight of （16.03±0.05） g were selected and randomly divided into 6 groups with 3 replicates each （1O fish per replicate）. They were reared in eighteen 100- L tanks equipped with a recirculating filtration system for a 56一day feding trial.The results indicated that， compard to the control group，an appropriate amount of sodium acetate significantly improved the weight gain rate and specific growth rate of S . schlegelii，with the peak effect observed in the SA4 group （1000mg/ kg （ ）.No significant differences were detected in the hepatosomatic index （HSI），intestinal somatic index（ISI），or viscerosomatic index（VSI） among groups （ P>0.05 ）．The feed conversion ratio （FCR） decreased significantly with increasing sodium acetate levels （ .P<0.05 ）.Under the present experimental conditions，adding sodium acetate to the feed significantly enhanced the growth performance of S .schlegelii，and the optimal amount of sodium acetate to be added was 1 628.08mg/kg
