Abstract:

An experiment was conducted to investigate the nutrient utilisation and growth performance of fingerlings of Clarias gariepinus fingerlings fed soybean meal-based diets supplemented with pineapple flavour as feed additive. Four treatments with three replicates each at 25 fishes per tank (mean weight of 22.32 g) were fed four diets (D1-D4) including the control and supplemented with powdered pineapple flavour at 0%, 1.5%, 2.0%, and 2.5% respectively in rectangular glass tanks filled with 30 liters of water each. Feeding was done at 5% body weight on daily basis throughout the feeding trial. Weights of the fish were recorded every week following food adjustment. The water quality parameters were within the range recommended for tropical fish culture. After 56 days, no significant differences (p<0.05) were observed in the proximate composition of the fish fed the different diets. However, protein increased (56.66±0.6% in D2 to 57.13±0.6% in D4) and fat content (4.75±1.1% in D3 to 5.05±1.2% in D4 while ash, crude fiber and nitrogen-free extract (NFE) reduced. The mean weight gain, food intake and the specific growth rate were significantly highest (p<0.05) in D3 (2%). Fish fed D3 (2%) performed favourably in terms of nutrient utilisation and growth performance compared to other formulated diets with the best record of the food conversion ratio. It was recommended that powdered pineapple flavour should be included at 2.0% in the diets of Clarias gariepinus fingerlings.
