Abstract

Full-fat soybean was processed by soaking in aqueous solutions of sodium sesquicarbonate, Na2CO3.NaHCO3.2H2O at 0.50%, 1.00%, 1.50% w/v concentrations at room temperatures for 24 hours. The processed soybean was sun-dried, milled, assayed and then used in formulating four iso-nitrogenous diets represented by diet T1 (0.50%), diet T2 (1.00%) and diet T3 (1.50%) respectively, diet T0 (0%) served as the control diet. The experimental fish, Clarias gariepinus fingerlings (initial mean weight: 5.91 + 0.01 g) were stocked at 20 per hapa of 1m3 and fed at 5% body weight. There was significant difference (P < 0.05) in mean weight gain (MWG) of the fish fed the treatment diets. Fish fed diet T2 had the highest MWG of 12.10 g. Similarly, there was significant difference (P < 0.05) in specific growth rate (SGR); food conversion ratio (FCR) and protein efficiency ratio (PER). Fish fed diet T2 had the highest SGR. PER and conversely the lowest FCR of 2.50, while fish fed diet T1 was poorly utilised with the highest FCR of 5.0 and lowest MWG of 4.45 g, SGR of 0.4% day-1 and PER of 0.80.

Key words: Growth performance; Clarias gariepinus, sodium sesquicarbonate, soybean.
