ABSTRACT: The study was designed to determine the growth response of African catfish (Clarias gariepinus) juveniles on diets with two vegetable-carried blood meals (brewers’ dried grains with blood meal (BB) and rumen contents with blood meal (RB)) as protein sources and alternatives to imported commercial fish feed (CatCo?). Diets, with BB and RB included at 10%, formulated to supply 45% crude protein and 4,300 Kcal digestible energy/kg in similarity with CatCo?, were used in a 49-day trial in plastic tanks (L × B × H: 53 cm × 37 cm × 29 cm; capacity 50 liters). Juveniles were evaluated in terms of mean final body weight (MFBW), mean weight gain (MWG), average daily gain (ADG), specific growth rate (SGR), average daily feed intake (ADFI), feed conversion ratio (FCR), protein efficiency ratio (PER), feed cost/g gain (FCGA), and mortality (as % survival). CatCo? was superior (P ? was similar (P
