Table 4 The yield parameters for Nile tilapia, Oreochromis niloticus and African sharptooth catfish, Clarias gariepinus fed on the mixed ingredients (MI) and rice bran (RB) diets during the study period

From: Supplemental effects of mixed ingredients and rice bran on the growth performance, survival and yield of Nile tilapia, Oreochromis niloticus reared in fertilized earthen ponds
