Species composition and seasonal variation of aquatic organism were collected by pot and trammel net in the coastal waters of Taean in 2018. A total of 4,501 individuals belonging to 78 species were collected in two type of gears. The dominant species in the study area was Strongylocentrotus nudus (Echinodermata). In the pot survey, crustaceans were the most common taxa, with 52 species including Palaemon gravieri, whereas fish were dominant in trammel net with 57 species including Okamejei kenojei. Clustering analysis revealed two distinct groups, indicating that the composition of aquatic organism varies according to oceanographic condition and environmental changes.
