摘　　要：Oyster cultivation is a pivotal economic industry in Hainan Island,South China,where a high oyster species diversity is shown.However,the specific distribution and biodiversity of oyster resources in the island have remained unclear.To elucidate the diversity of oyster species and their distribution there,307 oyster samples were collected from 29 sites in the intertidal zone around the island,and were identified using both morphological and molecular approaches.A minimum of 12 oyster species were identified in taxonomy,including Crassostrea species(C.gigas angulata,C.sikamea,C.iredalei,C.dianbaiensis,C.talonata,C.ariakensis,and C.hongkongensis),and Saccostrea species(S.malabonensis,S.mordax,S.echinata,S.circumsuta,and S.mordoides).The results revealed a remarkable diversity of oyster species along the coast of the island.Particularly noteworthy are that S.malabonensis and S.mordax constituted 36%and 22%of the collected specimens,respectively.This study provided a comprehensive overview on current state of oyster biodiversity in Hainan,serving as a valuable reference for conservation and research on species distribution and resource dynamics in oyster populations.
