  • What Are We Protecting? the Side-Effects of Spatial Closures As A tool to Mitigate Fisheries Bycatch

    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...

  • The Design of Hybrid individual incentive Mechanisms for Bycatch Reduction

    Creator:
    Haynie, Alan and Felthoven, Ron
    Abstract:
    After salmon bycatch levels reached record levels in 2006 and 2007 in the Bering Sea pollock fishery, the North Pacific Fishery Management Council (NPFMC) began consideration of a hard cap that would close the fishery if it were reached. The NPFMC asked for input from economists at the National Marine...

  • Protecting Marine Mammals in the U.S: Tradeoffs Between Public and Private Costs

    Creator:
    Magnusson, Gisele and Bisack, Kathryn
    Abstract:
    Implementation of the U.S. Marine Mammal Protection Act (MMPA) generates costs to both the public and private sectors. While many of the costs are complementary, some result in potential tradeoffs between various groups incurring these costs. Under the MMPA, if estimated bycatch of a species exceeds its Potential Biological Removal...

  • 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...

  • Implications of bycatch reduction strategies for the economic viability of mixed fisheries

    Creator:
    Martinet, Vincent and Thebaud, Olivier
    Abstract:
    There is growing recognition worldwide that the impacts of fishing on non-targeted components of marine ecosystems should be included in the assessment of fisheries sustainability. This leads to the inclusion of new constraints in evaluations of the long-term bio-economic performance of fisheries. In this paper, we analyze the implications of...

  • Hooker's Sea Lion Bycatch in New Zealand

    Creator:
    Kahui, Viktoria
    Abstract:
    With a value of NZ$ 85 million the seasonal squid fishery represents one of New Zealands main export earners. The majority of catch is taken by trawl from the Auckland Islands, 350 km south of New Zealand, which coincides with the main breeding and foraging range of the rare Hookers...

  • Halibut bycatch management implications for Area 2A and evaluation of an informal video

    Creator:
    Fruh, Erica
    Abstract:
    Concern over the incidental catch of non-targeted species in commercial and recreational fisheries has greatly increased. Public attention, negative publicity, controversies between differing fisheries and gear groups and the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act have led to an increased awareness of the issue. The Pacific halibut...

  • 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...

  • 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...
