Cover Story: In a genetically surveyed population of Atlantic Goliath Grouper, very high modeled estimates of variance in reproductive success and a correspondingly low modeled estimate of the genetically effective number of breeders were consistent with the observed distribution of close kin. Specifically, numerous genetically identified sibling pairs, including cross-year full siblings, were detected within a modest sample of ~300 adult specimens, which would be unexpected for an iteroparous marine species, unless the effective number of breeders was very low. Implications for conservation management of the population, as well as for genetic methods of abundance estimation, are discussed. View this paper
