| Research Abstract |
In situ investigations in 2007 and 2008 and satellite remote sensing data revealed the following : 1. Smaller phytoplankton was dominant in 2007 compared with past years. 2. Remarkable decrease in distribution area of chum salmon is anticipated and the salmon will have to move toward north such as the Arctic Ocean where sea will be shrunk. 3. Significant change in species of demersal fishes with rapid decline of sea ice extent was not recognized.
