Abstract: Resveratrol has gained great interest due to various reported health benefits. However, little information is available about its effects on the genetically improved farmed tilapia (GIFT), Oreochromis niloticus. Hence, this study was conducted to investigate the effects of dietary supplemental resveratrol on the growth, non-specific immunity, intestinal villi and liver microstructure of GIFT. (Method) Fish were fed four diets with different levels of resveratrol: 0, 250, 500 and 1000mg/kg. Eight non-specific immune enzymes in serum were measured on the 45th day. (Result)The results showed that the weight gain rate (WGR), specific growth rate (SGR) and feed coefficient (FC) significantly decreased (P<0.05) with increment of resveratrol at average 6.5%, 4.0% and 8.3% respectively. Activities of C3, C4, IgM, TNF-α, Hsp-60 and TRF decreased with increasing addition of resveratrol. Furthermore, differentSdegrees of damage were observedSin intestinal villi and liver in treated groups. (Conclusion)Therefore, addition of 0.1% resveratrol in diets can partially decrease non-specific immune enzyme activities, and damage the intestine and liver of tilapia.
