This study aimed to evaluate the effects of water temperature and catch frequency on biodiversity and distribution in the waters around Korea. We analyzed spatiotemporal catch data reported by fishermen and evaluated the fluctuations in the dominantly caught species based on the timing of the water temperature changes between 1999 and 2021. This study found an upward trend in the water temperature, and species diversity increased in the East, West, and South Seas after the water temperature changed. Relatively stable species diversity was maintained in the East Sea/Sea of Japan, although variability increased significantly in the West and South Seas. The distribution in the caught species showed that spp. and spp. were increasingly caught more consistently alongside spp. Moreover, this dominance was maintained even after the change in water temperature and was shown to be relatively less sensitive to water temperature changes.
本研究旨在评估水温及捕捞频率对韩国周边海域生物多样性和分布的影响。我们分析了渔民报告的时空捕捞数据，并根据1999年至2021年间水温变化的时间，评估了主要捕捞物种的波动情况。本研究发现水温呈上升趋势，水温变化后，东、西、南海水域的物种多样性增加。日本海/东海的物种多样性相对稳定，尽管西海和南海的变异性显著增加。捕捞物种的分布表明，[物种名称1]和[物种名称2]与[物种名称3]一起被更持续地捕捞。此外，即使在水温变化后，这种优势仍然保持，并且显示出对水温变化相对不敏感。
