Abstract

Aiming to study the survival rate and the development of piracanjuba, Brycon orbignyanus (Characiformes, characidae) fry, three experiments were set, with three repetitions by treatment. The experiments consisted of testing three different initial stocking densities (5, 15 and 25 piracanjuba larvae/L), three diets (Artemia sp, commercial ration and curimbatá larvae, Prochilodus lineatus) and two formats of hatchery tank (square and rectangular). The parameters of water quality were measured twice a day. The feeding was offered in a 4-hour interval, beginning soon after the mouth-opening of the fry. The results showed that different stocking densities and diets didn't influence the larvae survival, average weight, length and back-ventral height. However, the average weight and length were significantly better in the square tank
