Abstract: The present study was conducted to investigate the effects of different salinity levels on growth, feed utilization, body composition and digestive enzyme activity of silver pompano (Trachinotus blochii). Three treatment groups (designated as S1, S2 and S3) and a control group (S), each in triplicates, was established. The pompano in the control were kept at salinity of 34 ppt and those in S1, S2 and S3 were kept at salinity of 5, 15 and 25 ppt, respectively. After 56 days, growth performance was significantly higher (P<0.05) at S2 and S3 treatment. Body composition was significantly affected by salinity levels (P<0.05). The specific activities of amylase and total alkaline protease enzymes were significantly higher (P<0.05) for S2 and S3 respectively. The results collectively suggested that intermediate salinity of 15 ppt and 25 ppt improve the growth performance, feed utilization and digestive enzyme activity of pompano.
