Abstract:

The yellowfin seabream Acanthopagrus latus is widely distributed throughout the Indo-West Pacific. The genetic analyses of mtDNA control region sequence variation in samples from Chinese waters revealed a pattern of genetic structure between southern and northern samples (P < 0·05) and high levels of genetic diversity in this species. Significant isolation by distance between southern and northern locations (Mantel test r = 0·35, P = 0·04) and among northern populations (r = 0·55, P = 0·01) indicated that ocean straits and other barriers substantially limit gene flow. Phylogeographical analysis also revealed two major divergent mtDNA lineages across Chinese waters. For conservation, A. latus populations in Chinese waters should be divided into at least two management units for protection.
