Abstract
This paper aimed at evaluating the potentials of boiled Baobab (Adansonia digitata) seed meal as plant protein source in the diet of juveniles of Clarias gariepinus. A sixty-day feeding trial was conducted in 40L plastic aquaria tanks. Boiled baobab seeds meals were incorporated in diets at 0, 25, 50, 75 and 100% designated as diets D1 (Control), D2, D3, D4 and D5 respectively. All diets were iso-nitrogenous and iso-caloric. Juvenile Clarias gariepinus with initial mean weight 101.24±34g were fed ad lib on allotted diets twice per day for 60 days. Mean body weight gain in fish fed on D1 was highest with a value 901.22g and lowest in Diet 5 with a value of 250.39g. The mean daily weight gain in fish was highest in Diet 1 with a value of 15.4% and lowest in Diet 5 with a value of 4.17%. Specific Growth rate (SGR) of experimental fish was highest with a value of 3.62% in Diet 1 and lowest in Diet 5 with a value of 2.09%. Proximate composition of fish fillets fed on test diets show that the protein level in diet 21.88±0.11% in Diet 3 and 21.00±1.00% in D4 were significantly higher than the other diets while the crude fiber was highest in Diet 4 with a value of 2.90±0.17% and lowest in Diet 3 with a value of 1.93±0.12%. This study shows that up to 25% of boiled baobab seeds can be incorporated into the diets of juvenile C. gariepinus without any negative effects on growth of fish.
