Assessing the Consequences of Climate Change for Alaska and the Bering Sea
Marine fisheries are very vulnerable to climate change. Most of the research to date on the relationship between climate change and fisheries focuses specifically on how climate change may affect marine ecosystems and in turn abundance and harvests of specific marine species. This paper focuses on t...

Marine fisheries are very vulnerable to climate change. Most of the research to date on the relationship between climate change and fisheries focuses specifically on how climate change may affect marine ecosystems and in turn abundance and harvests of specific marine species. This paper focuses on the human effects-economic, social and political effects-of climate-driven changes in Alaska commercial fisheries, and what can be done to mitigate these effects. Alaska commercial fisheries are the basis of a major industry of economic significance not only to Alaska but also the nation. In 1995, the ex-vessel value (the value received by fishermen) of Alaska landings exceeded $1.4 billion, while the first wholesale value (the value after processing in Alaska) was almost $3.0 billion. Climate change may have significant effects on Alaska fisheries. Climate change is likely to reduce the abundance of some species while increasing the abundance of others, with resulting reductions or increases in commercial harvests.
