Outline of Final Research Achievements

We conducted field surveys in the East China Sea with international collaboration research between Japan and Taiwan, and found out the vertical and horizontal movement patterns of the Greater amberjack (Seriola dumerili) and dolphinfish (Coryphaena hippurus). Tagged amberjack were located primarily in eastern Taiwanese waters did not migrate northward to Japan, where use the middle layer (100m) below the seasonal thermocline, undertaking occasional to depths deeper layer (-500m). Tagged dolphinfish, which were released off eastern Taiwanese water and Kagoshima bay, stayed in surfaced mixed and did not dive beyond the thermocline. Our results suggested that the effect of global warming on subtropical migrating fish has already become remarkable in fish species that stay on the surface such as dolphinfish. On the other hand, the effects for fish species that stay in the middle layer such as Greater amberjack may be little.

Academic Significance and Societal Importance of the Research Achievements

温暖化による水温上昇が亜熱帯性回遊魚の分布に及ぼす影響については、シイラのような表層に滞在する魚種ではすでに顕著になっていると示唆される。一方、カンパチのような中層に滞在する魚種については、中層の水温上昇の程度が軽微であるため、現在のところ影響はほとんどないと考えられる。
本研究で得た行動情報と将来の温暖化予測に基づくと、南方性魚類の東シナ海への進入と滞在に及ぼす影響は魚種毎に異なることが示唆される。したがって、東シナ海の漁場の将来変化に対応する漁業方策については、まず、シイラやバショウカジキのような表層性回遊魚の日本への分布拡大および滞在時間の長期化に着目して施策を講じる必要がある。
