  • Descrição: The effect of diets containing different proportions of animal and plant protein supplemented with plankton on Rhamdia quelen larval growth and survival was tested. Two experimental diets were formulated, Diet-1 with 70% vegetable protein (soybean meal) and diet-2 with 70% animal protein (beef heart and fish meal); four feeding treatments (T) were studied: T1) 70% vegetable protein + filtering plankton sieve of 50-200 microns, T2) 70% vegetable protein + filtering plankton sieve of 50-200 microns, T3) 70% vegetable protein, T4) 70% animal protein. Larvae were handled at a density of 20 animals L-1 offering food daily to apparent satiation. There were no differences between T1 and T2 in final weight, total length, condition factor and survival between T3 and T4 the differences for these variables were not significant. Otherwise, significant differences were observed between the groups supplemented with plankton (T1 and T2) vs groups that received only vegetable or animal protein (T3 and T4). Plankton supplementation was more effective than offering vegetable or animal ration. The inclusion of 62.9% of soybean meal in the formulation (T1), apparently did not affect growth or survival.
