Abstract
The present study was conducted to measure the growth in terms of weight and length of different species of fish and to determine the proximate composition of fish at the final harvest. The effect of supplementation of three protein mixtures containing 40, 45 and 50% crude protein was determined. The results showed significant differences among weights of fishes raised under different crude protein levels of supplemental mixtures. The three fish species showed the best growth of fish in control group, which was comparatively better than with other two levels of crude protein. Body moisture and crude protein contents of fishes given mixtures containing 40% crude protein level remained the highest. However, fat content was highest in control. There existed inverse relationship between protein and fat contents of fish while direct relationship was found between body moisture and crude protein contents.
