Outline of Final Research Achievements

In the East Asian fishes, fish of southern and northern origins were found, as well as fish adapted to more temperate regions. The rich fish resources of East Asia, and the most heavily fished species in the world, are endemic to East Asia. How this East Asian fish fauna and resources were formed is interesting. Accurate species identification, international resource management, and conservation are fundamental, but even commonplace fish, such as the snapper, had taxonomic problems. In fact, it turned out that understanding the endemic fish fauna of East Asia is useful for future resource management, and it is interesting to explore the fish fauna of East Asia and its origin, which is derived from southern and northern fish faunas.

Academic Significance and Societal Importance of the Research Achievements

本研究により、日本を含む東アジアの魚類相や魚類資源の起源を探る研究であり、日本列島には南方系魚類と北方系魚類を起源とする魚類と、更に温帯域に適応した魚類がみられる。日本列島には南方系魚類と北方系魚類を起源とする魚類と、更に温帯域に適応した魚類がみられるので、東アジアの豊かな魚類資源、世界でも最も漁獲量の多い魚種は東アジアの固有性魚類であり、その固有性魚類が今後の東アジアの魚類の魚類資源にとって最も重要な魚類資源であり、資源管理や保全の方向性や提言が可能である。また魚類学の基礎的知見に貢献する。
