Cooperative Management of Trans-Boundary Fish Stocks: Implications for Tropical Tuna Management in the Pacific Island Region

Creator:: Tokunaga, Kanae
Abstract:: The trans-boundary migration of fish stocks creates spatial externalities, and hence, makes international cooperation beneficial. This study provides a model for the management of straddling and highly migratory fish stocks and examines the relationship between fish migrations and the benefits from cooperation. Previous studies on trans-boundary fish stock management have...

Who Opposes ITQs?

Creator:: Sutherland, Sara
Abstract:: When evaluating potential government interventions economists often consider whether a proposed policy is efficient. However, changes in policy can also result in changes in wealth. When politically influential individuals or groups see losses, efficient policies can become politically infeasible even if they increase wealth in aggregate. This paper examines political...

Least-Cost Bycatch Reduction Through the Biodiversity Mitigation Hierarchy

Creator:: Squires, Dale and Garcia, Serge
Abstract:: The Biodiversity Impact Mitigation (BIM) hierarchy provides an overarching conservation framework for bycatch reduction, and more broadly for biodiversity conservation. This framework includes four steps, which are implemented sequentially to: (i) avoid and (ii) minimize impacts; (iii) rehabilitate/restore impacted biodiversity; and (iv), compensate such impacts, usually elsewhere. The first three steps...

Market-Based Incentives for Vaquita Conservation

Creator:: Squires, Dale
Abstract:: The vaquita, a critically endangered marine mammal, is a bycatch to shrimp strawl and gillnet fisheries in the upper Gulf of California. Reducing vaquita bycatch, however, is complex. The fisheries are smaller-scale and major contributors of income and employment to coastal communities. Although tourism is increasingly important, fishing remains an...
