In a complete randomized design, Two hundred and ten fingerlings (weighing approximately 0.905±0.002 g all fish) were randomly distributed into 21 glass aquaria in 7 treatments (3 replicates per treatment). The first group was fed diet without any treatment (control), the second group was fed on diet supplemented with SeO₂ (0.3 mg selenium/kg diet) in fish diets, the third group was fed on diet supplemented with organic selenium supplemented; Sel-Plex^® (0.3 mg selenium/kg diet) in fish diets, the fourth group was fed the same diet and supplemented with zinc oxide (100 mg zinc/kg diet) in fish diets, the fifth group was fed on diet supplemented with EDTA zinc; C₁₀H₁₂N₂O₈ZnNa₂; (100 mg zinc/kg diet) in fish diets, the sixth group was fed on diet supplemented with clay 30 g bentonite/kg feed (3%) and the seventh group was fed on diet supplemented with nano-clay 30 g nano bentonite/kg diet. There was no clear effect of dietary feed additives on the water quality in the all experimental groups. All water parameters were stable and within acceptable ranges. Fish groups fed diets supplemented with zinc oxide or selenium oxide recorded higher final live body weight and daily weight gain, then those fed diets supplemented with EDTA zinc, organic selenium and natural clay. Dietary feed additives reduced the mortality rate of fish. Fish group fed diet supplemented with EDTA zinc and nano-clay recorded the lower mortality rate. Fish groups fed diets supplemented with organic selenium and EDTA zinc recorded the best feed conversion ratio. No statistical differences were observed in fish body dry matter, crude protein, ether extract and ash as affected by dietary feed additives. Fish groups fed diets supplemented with EDTA zinc, selenium oxide, zinc oxide or organic selenium recorded the higher final margin and income from body gain. The best final margin was obtained in fish group fed diet supplemented with EDTA zinc.
