Apparent digestion coefficient of dry matter in the feed stuffs used were above 70 per cent and there was no significant differences among themselves. The digestion coefficients of protein in the soybean meal were 95.63 per cent followed by fish meal 95.13 per cent, and wheat meal 84.70 per cent. The protein and fat digestion coefficients of fish meal and soybean meal didn't show any significant difference among (P0.05) themselves. White fish meal fat digestion coefficient was significantly higher (P0.05) than that of wheat meal. Fish meal and wheat meal showed significantly higher ash digestion coefficients (P0.05) compared to soybean meal. Carbohydrates in fish meal and soybean meal were poorly digested by T. tambroides fry. While wheat meal was well digested and significantly higher (P0.05) than those of the fish meal and soybean meal feed stuff. Fish meal and wheat meal showed significantly higher energy digestion coefficients (P .05) than that of soybean meal. As most of the feed stuffs were well digested, ingredient selection should, therefore, be based primarily on their protein content, amino acid composition and palatability.
