Species structure of the ichthyofauna of the inland waters of Phu Quoc Island, Gulf of Thailand, Vietnam

摘要

We performed the first large-scale study of the species structure of the fishes living in the inland water bodies of Phu Quoc Island and identified 97 species of bony fishes, which represent 41 families of 13 orders. Taking into account the results of earlier studies, we compiled a total checklist of the islands ich-thyofauna, which includes 99 species; one more species recorded in a previous publication on the ichthyo-fauna of the island can be added to this number, as well as 1520 mostly euryhaline species, which needed clarification of their states. Only one species on the checklist, Oreochromis niloticus, has been introduced to the island; 14 species, mostly of the family Gobiidae, have never been recorded in the faunas of other regions of Vietnam. Two new species, probably endemic to the island, have been found and described (in the genera Rasbora and Barbucca). Two more species of the order Siluriformes should probably also be described as new.
