This study investigated feeding management of yellowfin seabream, Acanthopagrus arabicas, juveniles under different feeding rates and its relationship to growth performance, survival, cannibalism and body composition. Thirty healthy fish (21.87±0.22g initial weight) were stocked in 12 separate net cages 3.4m³ assigned to four groups: F1, F2, F3, and F4 to receive feed at 3%, 5%, 7% and 9% body weight per day (bw/d). The juveniles were fed twice daily with a diet containing 42% protein for seven weeks. At the end of the feeding trial, group F3, fed at 7% bw/d, had significantly (P<0.05) higher percent weight gain, average daily weight gain and specific growth rate, followed by groups F2 (5% bw/d) and F4 (9% bw/d). The poorest growth performance was recorded in F1 (3% bw/d). Cannibalism was not seen in any treatment group, and survival was recorded 100%. In the whole fish body proximate composition, protein, ash and moisture showed no change while lipid levels in the fish bodies increased with increasing feeding ratio. Based on the results, 7% bw/d was the optimum feeding rate for J. arabicas under given experimental conditions.
