| contents | Spatiotemporal Patterns of Fish Diversity in the Waters Around the Five West Sea Islands of South Korea: Integrating Bottom Trawl and Environmental DNA (eDNA) Methods. Yoo, Young-Ji An, So-Yeon Lee, Seung-Hwan Lee, Soo-Jeong Gwak, Woo-Seok The waters surrounding the Five West Sea Islands of South Korea are ecologically important but challenging to survey due to their location within a strategic military zone, strong tidal currents, and significant tidal variation. To assess the fish community in this region, we conducted Korea's first parallel investigation combining traditional bottom trawl surveys with environmental DNA (eDNA) metabarcoding. Sampling was performed at 10 stations in March, May, and August 2023, and the relationship between fish species occurrence and environmental variables (water temperature, salinity, and depth) was examined. Dominant trawl-caught species included , , , and , each showing seasonal migration and spawning patterns associated with temperature changes. eDNA analysis detected nine additional species absent from trawl catches, such as and , demonstrating its sensitivity in identifying both migratory and sedentary taxa. Our findings confirm that eDNA surveys can complement traditional sampling, improving biodiversity assessment in regions with limited accessibility and complex oceanographic conditions. |
