The tendency of global warming due to the increased CO2 in atmosphere resulted in warming of ocean surface, and the increasing rate of sea surface temperature was the greatest in polar region. The Arctic Ocean which is surrounded by the Eurasia and North America has shown an enhanced seawater temperature since 1990s. Therefore it is projected that the most part of the Arctic Ocean during summer period would be open sea by the end of this century. Opening of the Arctic Ocean with warm temperature allows seasonal movement of fish populations from the subarctic areas such as the Barents Sea in the North Atlantic and the Bering Sea in the North Pacific. If fish populations could settle in Arctic area successfully with a suitable growth pattern, it would be very helpful to solve out the current food security issue of human society. With current information we have collected, however, it might not be possible to answer the questions on which species could be propagated to Arctic successfully. Based on ecological knowledge and experience in marine ecology, this paper discussed the necessary conditions to form a new fishing ground, reviewed the Arctic activities conducted by major coastal nations as well as international organizations, and suggested some consideration on research activities in Arctic Ocean needed to keep healthy ecosystems and rational utilization of fishery resources in the future.
Abstract
The tendency of global warming due to the increased CO2 in atmosphere resulted in warming of ocean surface, and the increasing rate of sea surface temperature was the greatest in polar region. The Arctic Ocean which is surrounded by the Eurasia and North America has shown an enhanced seawater temperature since 1990s. Therefore it is projected that the most part of the Arctic Ocean during summer period would be open sea by the end of this century. Opening of the Arctic Ocean with warm temperature allows seasonal movement of fish populations from the subarctic areas such as the Barents Sea in the North Atlantic and the Bering Sea in the North Pacific. If fish populations could settle in Arctic area successfully with a suitable growth pattern, it would be very helpful to solve out the current food security issue of human society. With current information we have collected, however, it might not be possible to answer the questions on which species could be propagated to Arctic successfully. Based on ecological knowledge and experience in marine ecology, this paper discussed the necessary conditions to form a new fishing ground, reviewed the Arctic activities conducted by major coastal nations as well as international organizations, and suggested some consideration on research activities in Arctic Ocean needed to keep healthy ecosystems and rational utilization of fishery resources in the future.
