Abstract: This study was designed to investigate the effects of vitamin C supplement on growth performance and immune responses of Waigieu seaperch (Psammoperca waigiensis) at juvenile stage, 90 fish of an average initial weight of (33 ± 0.1 g and 14. ± 0.1 cm) were stocked in 10 tanks (20 L) during 30 days and fed with different level of supplemented feed with vitamin C 0, 150, and 400 mg/kg with three replicates for each and fed twice a day 8:00 and 16:00 hr. At the end of experiment both growth and hematological parameters were determined, results revealed that there was no significant difference in survival ratio (SR) was observed during among the experimental groups, fish fed with 400 mg/kg had significantly (P<0.05) higher specific growth rate, protein efficiency ratio; and significantly (P<0.05) better feed conversion ratios than non-supplemented fish. Hematological parameters showed a significant increase (P<0.05) with dietary AA level was increased as supplemented diets increase. Proximate compositions of the experimental such as average crude protein, crude fat, moisture, ash entire treatment diets utilized were no significant difference (P>0.05). Our data show that ascorbic acid is essential for Waigieu sea perch hematological and growth performance parameters.
