IntroductionAquaculture technology has evolved the push toward faster growth and higher production of fish has involved the enhancement or replacement of natural foods with prepared diets. Shiau et al. (1989) indicate that when dietary protein was suboptimal (24%), up to 67% of the fish meal protein in tilapia feeds can be replaced by soybean meal protein without any adverse effect on tilapia grow...

Our study can be cited in the other study in the relation between protein and energy level or source and dietary zinc addition
