Genetic Pattern and Demographic History of Orange-Spotted Grouper (Epinephelus coioides) in the South China Sea by the Influence of Pleistocene Climatic Oscillations.

ABSTRACT: Orange-spotted groupers (Epinephelus coioides) are commercially important fish species that inhabit coral reef areas and are distributed across tropical coastal regions throughout the Indo-West Pacific Oceans. This study aims to assess the phylogeographic structure of E. coioides by analyzing 180 individuals collected from six locations along the coast of mainland China and Hainan Island, using the mitochondrial Cyt b gene and 17 microsatellite DNA markers. The mitochondrial DNA analysis revealed high haplotype diversity (0.882), while the microsatellite DNA data showed an average of 8.677 alleles among the six populations, indicating that all populations exhibit a high level of genetic diversity. The presence of two distinct evolutionary lineages of E. coioides
