Abstract

The present study was conducted to determine the effect of using turmeric extract (Curcuma zedoaria) on non specific immune of grouper (Epinephelus fuscoguttatus). During the study, fish were fed a diet containing 0, 0.5, 1.0, 2.5 g extract/kg feed twice a day for 14 days. Observations of non-specific immune parameters such as respiratory burst activity, chemiluminescent response, phagocytic activity, superoxidase dismutase (SOD) and lysozyme activity were sampled at 0, 1, 2, 4, 7 and 14 days. The results showed that fish fed C. zedoaria with 0.5 g/kg feed affected non-specific immune responses, and showed significant effect in the short term. On contrary, for long-term administration causes a decrease and inhibition of non-specific cellular defense activity. Thus, this study concluded that the administration of turmeric extract added to the feed can act as an immunostimulant and increase the non-specific immune response in grouper (E. fuscoguttatus).
