Economic impacts of climate change on sustainable tuna and billfish management: insights from the Western Pacific

This paper examines long-term economic implications of climate change on ocean fisheries, fishing patterns and the management of both fish stocks and fishing nations. General fishery management theory identifies areas of the most immediate impact from climate change, which are assumed to be rises in sea temperatures and altered ocean current movements. The Western Pacific Ocean area is used as a case study to illustrate components of both the biophysical and economic impacts that should be considered in any policy development. These factors influence policy issues for domestic and foreign fishers, with additional risks in these fisheries due to climate change.
