The free-choice feed and regulation of protein intake were investigated in juveniles reverted males of tilápia do Nilo, Oreochromis niloticus. During the experiment 1000 fish (reverted males) with similar weigth and length were maintained in eight aquariuns supplied with recirculated water (groups of 125 fish each aquarium). Fish were fed by demand-feeders, containing the two experimental diets, formulated to contain 15% and 40% protein each and distributed in four treatments (A: 15% protein diet on one hand and 40% protein […]
