Abstract

 

Comparing the effects of raw, toasted and amino acid enriched diets on the growth and nutrient utilization of Clarias gariepinus allocated in to eight different treatments with two replicates each with 10 Juveniles in 16 aquaria tanks. Eight different diets containing 40% crude protein each were compounded and fed to the fish at 5% body weight for 16 weeks. Diet T1 was the control while diet T2 was the conventional diet (coppens) purchased commercially. Diet T5 which had a 50% toasted soybean inclusion and contained 50g yellow maize, 20g toasted .soybean. 10g fish meal, 13g Groundnut cake, 2.5g vegetable oil. 2.0g starch and 0.5g vegetable oil had the greatest growth rate which were significant higher ((P<0.05) than those fish fed on other diets. Diet T7 (100% raw soybean with methionine and lysine) containing 50g yellow maize 30g raw soybean. 13g groundnut cake. 2.5g vegetable oil. 2,0g starch and 0.5g vegetable oil followed diet T5. Average weight gain, specific growth rate (SGR), Average daily weights gain, protein efficiency ratio (PER), feed conversion ratio (FCR) and Net Nitrogen retention were significantly higher (P<0.05) in fish fed diet T5 and diet T7 in the experiment. The results showed that fish fed toasted soybean based diet had the highest average weight gain (A.V/.G) of 432.55g, specific growth rate (SCR) of 3.38%/day and food conversion ration 'FCR} of 5.78. The juveniles fed raw soybean gave the least growth performance. It could be concluded in practice that toasted soybean based diet is optimal for growth of C. gariepinus juveniles, mortality rates recorded during the dietary trial ranged between 30% in fish fed diet Ts to 100% in fish fed diets T,. 73. T4, T5 and T6. The results were discussed in relation to fish feed production and its implication for fish culture intensification in Nigeria.
