Abstract


The Pacific red snapper, Lutjanus peru, is a commercially important species throughout its range, making it a good candidate for aquaculture, but there are few data regarding environmental conditions and their influence on early development of this species. Temperature is one of the main factors affecting embryo and larval development in marine fish. In this paper the effects of different temperatures on hatching rate, growth, consumption of yolk sac and oil droplet and the formation of the digestive system and eye pigmentation were evaluated in larvae of this species under experimental conditions. Eggs incubated between 20 and 32 °C showed hatching rates higher than 90%. However, larvae maintained at 26 °C showed significantly larger notochord length and were first to complete the pigmentation of the eyes and the formation of the digestive system when still possessing enough reserves in the yolk sac. Therefore, it is recommended that the incubation of eggs and larval rearing in Pacific red snapper take place between 25 and 26 °C.
