To investigate the effectiveness of cube-type artifical reef with eight inner blades a catch survey using gillnets was conducted in the Oeyeondo Boryeong-city in March, May, July, and November 2023 in divided areas. A total of 536 individuals were caught, and they are classified into 15 orders, 25 families, and 31 species. The dominant species was Raja pulchra (180 individuals, 35.7%). CPUE and species diversity index showed high values in experimental area and control area, respectively. The dominance index was different for each category. As a result of the survey, a positive effect on fish reefs was confirmed. However, the differences by region are minimal, so continuous surveys are necessary.
