The local fish markets were surveyed, and fishermen and fishmongers were interviewed to get fishery information. A total of 57 fish species belonging to 41 families and 14 orders were recorded, among which, 55 were bony fish, and 2 were elasmobranch. There were 41 fish species belonging to warm-water fish, and 37 fish species belonging to benthonic fish. The faunal characteristic was mainly of Northern Pacific and Indo-Pacific fauna. Devastating fishing and environmental pollution were the most serious threats to the local fishery resources, and some countermeasures were proposed for conservation and management of the resources.
