We collected fish from the intertidal zone of Seonyu-do Island in order to find out the composition of fish species by using hand net and kick net from March to October 2022. During the investigation period, a total of 2,707 individuals from 9 Orders, 19 Families, 45 Species were collected, and the dominant species was identified as Nuchequula nuchalis and the subdominant species was Favonigobius gymnauchen. By family group, the largest number of fishes in the Gobiidae were 13 species, followed by the Scorpaenidae and the Stichaeidae were 4 species. In this study, genus Clariger was discovered for the first time off the West sea, and it is estimated that fish living on the southern coast are moving northward due to an increase in the water temperature of the West Sea and detailed research is needed.
