Outline of Final Research Achievements

In order to sustainably utilize fishery resources, it is essential to understand variable factors affecting them for their appropriate management. The present study aims to contribute to the development of effective management strategy by clarifying spatiotemporal dynamics of the genetic diversity and population structure of fishery resources. Mitochondrial D-loop sequences of chub mackerel (Scomber japonicus), Japanese horse mackerel (Trachurus japonicus), and Japanese sardine (Sardinops melanostictus) mainly caught in Nagasaki and Tottori were obtained and analyzed. The results indicated that genetic diversity of these fish species were extremely high all the year-round and their populations in the South China Sea, East China Sea, and Pacific Ocean apparently consisted of a single genetically-identical population. This strongly confirms the importance of internationally cooperative management of fishery resources.

Academic Significance and Societal Importance of the Research Achievements

本研究では、これまで曖昧になっていた地域間や系群間の関係について遺伝的に明らかにし、水産資源が広く分布域全体に渡ってつながっていることを示した。このことはマサバ、マアジなどの水産資源を持続的に利用していくためには国際的な取り組みが必要不可欠であることの科学的根拠となるものである。また、過去の資源変動が極めて大きいマイワシでは、仮に資源量が回復したとしても遺伝的多様性が失われた状態であることを示唆するデータも得られており、今後の資源管理の新たな課題を提案している。このような点において本研究は水産資源の持続的利用を実現するための基盤的な研究としての意義があるものと考えられる。
