Unveiling the Mesopelagic Ichthyofauna in Korean Waters: Ecological Significance and the Need for Precautionary Management
摘要
Mesopelagic fishes (200–1,000 m) account for a substantial portion of global marine biomass and play pivotal roles in marine food webs and the biological carbon pump. Despite their ecological significance, taxonomic baselines and quantitative information on mesopelagic fishes in Korean waters remain limited. Our study establishes a systematic inventory of mesopelagic fishes potentially occurring in Korean waters by cross-referencing international taxonomic literature—including FAO reports and major identification guides from the Atlantic, Pacific, and Indian Oceans—with the domestic fish inventory provided by the National Institute of Biological Resources. We identified 24 species across 13 families as potential inhabitants of Korean waters. Although our results are limited by their reliance on literature review rather than in situ quantitative assessments, this study provides the first comprehensive taxonomic foundation for mesopelagic ichthyofauna in Korean waters. By highlighting their pivotal roles in the biological carbon pump and marine food webs, we emphasize that current research gaps must be addressed through an integrated survey system. Ultimately, this work serves as a foundational step toward establishing a precautionary management framework that aligns with global sustainability goals amidst a changing climate.
