| Tiivistelmä: | The substantial growth of the global salmon aquaculture industry has produced important implications for Alaskan salmon fisheries as increased supplies of farmed product have resulted in declining prices of both farmed and wild species. In the case of Bristol Bay sockeye salmon, falling prices and declining profit margins have caused participation in the limited-entry fishery to diminish. This study formally examines the market interactions between the aquaculture and commercial fishery sectors by revising the Homans and Wilen (1997) model of regulated open access to the case of restricted access fisheries. The econometric model shows that limited entry regulations initially succeeded to extract rents from the Bristol Bay fishery; however, the rents were gradually dissipated resulting from overcapacity and the impact of falling ex-vessel prices. The emergence of aquaculture gives a strong rationale in favor of right-based approaches to managing fisheries in Alaska. |
