Evaluating the Efficacy of Predicting Bycatch Mortality Using Reflex Impairment through an Assessment of Crab Discards

Creator:: Yochum, Noëlle
Abstract:: All animals that interact with fishing gear are not necessarily captured, and all animals that are captured are not necessarily retained. Fishing practices and gear configuration, management regulations, and markets dictate which animals ultimately are retained or discarded. The impact of a fishery and the efficacy of management regulations can...

An Economic Approach to Optimizing The Level of Observer Coverage

Creator:: Kvamsdal, Sturla and Stohs, Stephen
Abstract:: The US Magnuson-Stevens Act authorizes the use of onboard observers to monitor commercial fisheries catch and bycatch (PFMC 2003). A question of concern in implementing an observer program is that of the appropriate level of observer coverage. Current practice varies by fishery; for example, the California-Oregon drift gillnet fishery for...

Pacific Coast Groundfish Fishery Assessment and Management: Incorporating Nearshore Surveys into the Fishery Management Framework

Creator:: Haven, Katlyn M. M.
Abstract:: The Pacific coast groundfish fishery is a diverse, important and lucrative commercial and recreational fishery. Part of this fishery’s monitoring process includes regular fishery-independent surveys for stock assessment. Although these fishery-independent surveys are cost-effective, they are susceptible to scientific uncertainty, and they do not currently sample in nearshore (water depth...

Economic Efficiency and Sector Allocations in the New England Groundfish Fishery: A Comparison of Sector and Non-Sector Vessel Performance

Creator:: Gilbert, Ben
Abstract:: The case for assigning private property rights in fisheries has been thoroughly studied but has lead to a new debate over whether rights should be allocated to groups or individuals. The New England groundfish fishery provides a rich context in which to study this question. Beginning in 2004, several dozen...

Markets, Pooling and Insurance for Managing Incidental Catch In Fisheries

Creator:: Holland, Dan
Abstract:: Bycatch is a nearly universal problem for fisheries, and it is becoming increasingly common to place strict limits on allowable bycatch, either on individuals or as a cap on an industry sector s bycatch. Individual bycatch quotas strengthen individual incentives to avoid bycatch and may reduce the likelihood that the...

Incentive Systems for Reducing Bycatch In the Alaska Pollock/Salmon Fishery

Creator:: Wilen, James
Abstract:: The bycatch problem has remained troubling and persistent, even in fisheries that have rationalized their target fisheries. The Alaskan Pollock fishery is an example of a fishery struggling to contain the bycatch of salmon in spite of a transformation of incentives associated with a harvester coop system in the target...

Bioeconomic Dynamic Modelling of the Chilean Southern Demersal Fishery

Creator:: Cerda-D'Amico, Rene, Gonzalez Poblete, Exequiel, and Molina Hernandez, Renato
Abstract:: The demersal fishery of southern Chile is a complex system including multiple species, fishing fleets and markets. Fishing activity is conducted under a rights-based system for southern hake (Merluccius australis) and hoki (Macroronus magellanicus), where a TAC is allocated in an even manner among fleets and operators. New management approaches...

Emerging Technologies in Fisheries Science: A Transdisciplinary Report

Creator:: Firl, Alrik, Haven, Katlyn, and Newton, Samm
Abstract:: The Pacific Coast Groundfish Fishery harvests a diverse and large grouping of fishes, but it did not become heavily fished until around WWII. This makes the groundfish fishery a comparatively young fishery. Despite its youth, it is one of the largest and most lucrative fisheries in Oregon—with a current harvest...

Demonstrating the Evolution towards Ecosystem Management in Regional Fishery Management Organizations

Creator:: Brinson, Ayeisha and Die, David
Abstract:: In ecosystem-based fishery management, the ecosystem comprises the natural sub-system and also human components, including user groups, institutions and the processes of management. Regional Fishery Management Organizations (RFMOs), particularly those designed to manage tunas, were not established with an ecosystem view of the pelagic environment. However, tuna RFMOs have evolved...

From Mobile Closures to individual incentives: Chinook Salmon Bycatch Reduction Efforts in the Bering Sea Pollock Fishery

Creator:: Haynie, Alan
Abstract:: Bycatch is repeatedly noted as a primary problem of fisheries management and as the foremost negative impact of commercial fishing. In the Bering Sea pollock fishery, salmon bycatch reduction measures have included gear modifications but have principally consisted of area closures. Bycatch levels of chum and Chinook salmon have risen...
