Densidade de estocagem na produção de juvenis de duas espécies de lambaris em sistema de recirculação

Abstract

ABSTRACTThe aim of this study was to evaluate the stocking density for juveniles for two different species of characins (Astyanax bimaculatus and A. scabripinnis) in a recirculation system. An experiment was carried out with each type in which twelve tanks in each experiment were divided into four treatments (0.25, 0.75, 2.25 and 6.75 fish.L-1), in triplicate. At the end of cultures the stocking density 0.75 fish.L-1 showed greater weekly growth and final weight, for both species, and it is recommended for cultivation under similar conditions.
