Species Composition and Seasonal Variations of Fish Communities in Coastal Waters off Wang Dol Reef

This study was investigated seasonal variation and species composition of fish species at Wang dol reef from November 2019 to August 2020. A total of 31 fish species was occurred, and the dominant fish species were dermesal fishes. The number of individuals of fishes was higher at August 2020, lower at March 2020. The number of species was higher than another study. Thamnaconus modestus was dominant, than Eopsetta grigorjewi, Hexagrammos otakii and Sebastiscus marmoratus were followed. Seasonal variation of dominant species that Eopsetta grigorjewi in March 2020, Hexagrammos otakii in May 2020 and Thamnaconus modestus in November 2019 and August 2020. These results indicated that difference between water temperature and diet community.
