ADDITION OF CURCUMA (CURCUMA XANTHORRHIZA) AS AN ANTIOXIDANT ON AFRICAN CATFISH (CLARIAS GARIEPINUS) COMMERCIAL FISH FEEDING

African catfish cultivation using a high stock solid system can cause increased stress and disease susceptibility to African catfish. Thus, it is necessary to use natural ingredients of antioxidants as a substitute for chemicals or antibiotics to avoid resistance. This study aimed to determine the effect of curcuma flour addition on increasing leukocyte counts, leukocyte differential and survival rate as parameters of African catfish cultivation success. This study was an experimental study, by the completely randomized design (CRD) with 4 treatments and each treatment received 5 replications so there were 20 experimental units. The variables observed were doses of curcuma flour, total leukocytes, differential leukocytes and the survival levels of African catfish.The results of this study indicated that the addition of curcuma flour in African catfish (Clarias gariepinus) feed formulation were quite effective to influence the increase in leukocyte counts and differential leukocytes in African catfish bodies, although the survival rate was still lower than control (without curcuma).The addition of curcuma (Clarias gariepinus) flour in catfish feed formulation could increase leukocyte counts, leukocyte differential and the survival levels of African catfish to obtain maximum results. The most effective dose of curcuma flour was by mixing 4% curcuma flour in 100% formulation feed
