Resumo: | The tropical seabass Lates calcarifer was introduced in Tahiti in 1984 and then was domesticated without other introduction. Three successive generations have been obtained in captivity. Tissue samples of the 38 animaIs which represent the total Tahitian broodstock were preserved in alcohol to be genotyped with four microsatellite markers (Yue et al., 2001). Three of four described markers were successfully transferred to the laboratory of genetics of Tahiti (marker LcaM01, LcaM02, LcaM03), as the revelation technology available locally did not allow the use of LcaM04 in routine. The results show that the genetic diversity of the tahitian broodstock is not equivalent of the one of the species, which could be explained by the small size of the founder population, which is consistant with the history of the Tahitian population. The structuration of the 4th generation into several batches obtained from different parents appears to be the minimum management procedure to limit inbreeding.
