Abstract: Waigieu Sea perch (Psammoperca waigiensis) is one of the most commercially and nutritionally important species. However little research has been done to explore the fish size, feeding rations on growth performance and immune responses of Waigieu Sea perch at juvenile stage. This paper derivers form an in depth study of the effect of feeding rate on growth performance and heamatological parameters. 198 fish of an average initial weight of (17±0.01 g and 8.5±0.01 cm) for group of small size and an average initial weight of (20±0.21g and 11±0.2cm) for group of big size. Juvenile were collected from a luong son hatchery were stocked in 18 tanks (20 L) during 42 days. All fish were fed the same diets contained 44% crude protein at feeding rate of 3, 5 and 7% of body weight with three replicates per treatment fish were fed twice per day at 08:00 and 16: 0 hr. Results revealed that feeding rate tested did not influence survival and there was a significant differences in growth performance and heamotological parameters in both fish size with feeding rates at 5% (P<0.05). There was no significant difference (p>0.05) in whole body composition in all feeding trails. Nevertheless feeding rate of 5% of body weight daily can’t be considered as the optimal feeding rate for Waigieu Sea perch further research should be done on different size and different feeding rate to enhance fish growth and heamatological parameters.
