Study of genetic diversity of orange-spotted grouper, Epinephelus coioides, from Thailand and Indonesia using microsatellite markers.

Genetic diversity of Epinephelus coioides (Hamilton, 1822), which inhabits coastal reefs from the western Indian Ocean to the western Pacific Ocean, was studied based on four polymorphic microsatellite loci. Two hundred and fifty individuals were collected from two locations in Thailand (Nakornsrithammarat-N and Trang-T) and four in Indonesia (Sibolga-S, Lampung-L, Jepara-J, and Flores-F). The genetic variation of E.
