Abstract Excerpt:
Since the 2000s, there has been a decreasing trend in southern populations (e.g., Japan, Korea, and British Columbia in Canada) of chum salmon (Oncorhynchus keta) but northern populations (e.g., Russia and Alaska in the USA) are stable or increasing. In the 2000’s, it was predicted that: 1) the population of Japanese chum salmon would be half of its maximum carrying capacity by the 2010’s due to internal natural growth rate. (Kaeriyama 2004), and 2) global warming affected the distribution of chum salmon in the North Pacific in this century (Kaeriyama 2008). Objectives of this paper are to 1) evaluate the influences of a warming climate and changing ocean conditions on distribution, growth, survival, and carrying capacity for Pacific salmon, and to 2) address potential progression of global warming for establishing the sustainable conservation and management of Pacific salmon.
