Abstract

Effects of density of organisms on survival percentage was determinate in juvenile of the conch “tote” Pomacea flagellata, egg masses were collected in the pond of aquaculture laboratory and incubated under laboratory conditions, at temperature (29 ± 1°C) to the hatching of the conchs. At hatching, the organisms were distributed in aquariums of 40 liter and fed with chaya (Cnidoscolus aconitifolius) at libitum during all experimental period of 30 days. Six different densities were evaluated (50, 100, 150, 200, 250 and 300 organism/aquarium), each one with two replicates. The highest survival percentage (88%) was obtained at the densities of 50 and 150 org/aquarium), at density of 200 org/aquarium was registered the lower percentage of survival with the 71% of the live organisms at the end of the study
