IBARRA CASTRO, Leonardo et al. Generation cycle closure of the spotted rose snapper, Lutjanus guttatus, in captivity. Rev. biol. mar. oceanogr. [online]. 2012, vol.47, n.2, pp.333-337. ISSN 0718-1957.

The spotted rose snapper, Lutjanus guttatus, is culture in several Latin American countries. The present study reports the generation closure with juveniles obtained from wild adults which matured and spawned at a Mazatlan laboratory (Mexico). F1 fish were sexually matured at 2 years of age, and spawning was induced in 2 successive years. F2 juveniles were reared until their sexual maturity and spawned at the same laboratory. Result indicate that a reliable supply of laboratory reared spawners can be achieved, avoiding the wild spawners dependence and allow the development of selection and genetic improve programs.

Keywords : Lutjanidae; F1 broodstock maturation and spawning; generation closure.
