At the present, the global warming has positively affected for increase growth at age-1 and survival of Hokkaido chum salmon. In the future, however, this global warming will affect decrease in carrying capacity and distribution area of chum salmon in the North Pacific Ocean. For establishing the sustainability on seafood security and ocean ecosystem conservation, we have 3 questions. 1) How can we use the ocean organisms as -seafood in the future? 2) What do we need for seafood security and ocean ecosystem sustainability in present and future? 3) 
How do we establish the sustainable fisheries management based on the ecosystem approach? In order to answer these issues, we should know carrying capacity are limited and fluctuated in ocean ecosystem, that fisheries industry are emphasized not only the economic efficiency, but also the ecosystem approach. As the education, we need paradigm shift from the traditional fisheries science for only fisheries to the ecological fisheries science for the protection of marine ecosystems and human food resources in order to be human well-being in future generation. Adaptive management and precautionary principle are essentially important to establish the sustainable fisheries management based on the ecosystem approach.
