Creator:: Abbott, Joshua, Lloyd-Smith, Patrick, Willard, Daniel, and Adamowicz, Wiktor
Abstract:: Saltwater recreational fisheries receive little attention compared to their commercial counterparts. Yet recreational fisheries can suffer from many of the same symptoms of open access as commercial fisheries. Regulations designed to allocate a scarce supply, such as seasonal closures augmented with bag and size limits, can result in significant losses...

Creator:: Morency-Lavoie, Félix, Nøstbakken, Linda, and Abbott, Joshua
Abstract:: Parasites and diseases represent major challenges in aquaculture. In the Norwegian salmon farming industry, costs associated with treatment of sea lice are surging and reached 5bn NOK or 10% of the industry’s total export value in 2015. In addition to the direct impact on production, sea lice affect the industry...

Abstract:: The Alaska non-pollock multi-species catcher processor trawl fishery, referred to as the Amendment 80 fishery since 2008, is an endlessly fascinating subject from the perspective of an economist. A diverse group of companies and vessels, emphasizing different species mixes from a multi-species ecosystem, targets fish across the Eastern Bering Sea,...

Creator:: Hutniczak, Barbara, Abbott, Joshua, Seong, Do Yun, and Fenichel, Eli
Abstract:: Fisheries managers are increasingly expected to manage fisheries in an “ecosystem-based” manner – accounting for ecological interdependencies across species and their coupling with the physical environment. Yet managers lack rigorous, bioeconomic EBM indicators to assess tradeoffs and measure whether the natural capital in exploited ecosystems is sustainably managed. We build...

Creator:: Abbott, Joshua and Willard, Daniel
Abstract:: Recreational fishing in the Gulf of Mexico has followed a familiar pattern to that observed in many commercial fisheries: fishing under regulated open access has promoted a “race to the fish” with cascades of shorter seasons, shrinking bag limits, and significant discards. These restrictions may have significant effects on angler...

Creator:: Abbott, Joshua, Lloyd-Smith, Patrick, Willard, Daniel, and Adamowicz, Wiktor
Abstract:: Many recreational fisheries are managed under regulated open access governed by seasonal closures and bag limits. This approach has often promoted a “race to the fish” with cascades of shorter seasons and shrinking bag limits. These restrictions may have significant effects on angler welfare by inefficiently allocating fish across anglers,...

Creator:: Reimer, Matthew, Abbott, Joshua, Wilen, James, and Haynie, Alan
Abstract:: Multispecies fisheries add additional complexity for rights-based management implementation. Imperfectly selective fishing gear may make it difficult for fishermen to match their catch composition with the portfolio of total allowable catches chosen by management. If fishermen can perfectly target their catch, the problem of matching catches with quota allocations declines...

Creator:: Reimer, Matthew, Abbott, Joshua, and Wilen, James
Abstract:: The notion of individual transferable quotas (ITQs) has permeated the fisheries economics literature over the last 40 years. The most long-standing prediction about ITQs has been extensively documented, namely that transferable property rights to harvest induce changes along the extensive margin via consolidation of quota among a smaller number of...

Creator:: Fenichel, Eli and Abbott, Joshua
Abstract:: Recreational fisheries are severely understudied by fisheries economists, in spite of their growing importance in the context of fisheries management. While recreational demand models have been extensively applied to recreational fisheries, they have rarely been successfully integrated with bioeconomic models to evaluate policy changes. Furthermore, theoretical models of open access...

Creator:: Abbott, Joshua and Haynie, Alan
Abstract:: In the quest to limit the bycatch of non-target species, marine protected areas (MPAs) have been frequently utilized. MPAs are popular with ecologists and fishery managers because of their relative ease of administration, habitat protection benefits, and the widespread acceptance of MPAs as an instrument of choice for the ecosystem...
