%X it is important to search for sustainable alternatives with byproducts for replacing fish meal in diets for weight gain in red tilapia (oreochromis spp.) cultured in floating cages at 27.8 ∼c. in the present study, four isoprotein diets (26 %) (treatments: t; 0 %, t0; 14 % t14; 16 % t16, and 18 % t18) and isoenergetic diets (2.7 kcal g-1 feed) were formulated, using a by-product mixture of sugar cane, enriched with acid fish-silage (sugar cane protein meal) as substitution of fish meal. four hundred and twenty tilapia males (58.34㊣0.01 g) were used in this study, fed for 60 d. the experimental design was completely randomized with seven rectangular cages per treatment (0.256 m3; 0.8x0.8x0.4 m) left hanging above a circular concrete pond (8 m diameter and 2 m high) with 15 fish per cage. data analysis, conducted by a one way analysis of variance, indicated that for t0 and t14 there were no significant differences (p>0.05) in final weight, growth rate, protein efficiency rate, factor of conversion and feed efficiency. the fish in treatments t16 and t18, however, showed less performance. we conclude that up to 14 % of sugar cane protein meal may be included in diets for weight gain in red tilapia without affecting productive indicators.
