摘要： The black sea bream, Acanthopagrus schlegelii (Bleeker, 1854), has a great commercial value and a long history of stock enhancement in most coastal cities in China. The stock enhancement programs made significant achievements and contributions in increasing fishery yield, but few information was reported regarding the genetic effects on the wild population resulting from the releasing. In order to elucidate the potential genetic effects associated with stock enhancement releases, sequence variation based on the mitochondrial control region was investigated to characterize the genetic resources of black sea bream in Pearl River Estuary. The results showed that the broodfish and hatchery-released fish were characterized by lower genetic diversity indices compared with wild populations. In addition, after releasing, the genetic diversity was lower in the samples of Pearl River Estuary than other wild populations. The results of pair-wise FsT value and AMOVA revealed low genetic differentiation among hatchery populations, samples in Pearl River Estuary and wide populations nearby the stock areas, which was consistent with the previous study. Hence, the black sea bream stock enhancement may have affected the genetic diversity of wild populations in Pearl River Estuary. In further stock enhancement of A. schlegelii, it is necessary to routinely monitor the genetic effects of stock releasing and improve the genetic management. (C) 2020 Published by Elsevier B.V.
