  • Using Choice Models to Inform Marine Spatial Planning: A Case Study of Marine Protected Area Designs off the U.S. West Coast

    Creator:
    Wallmo, Kristy and Kosaka, Rosemary
    Abstract:
    Marine spatial planning (MSP) is a process that planners can use to make decisions about different, sometimes conflicting, ocean uses.  The process is intended to be participatory and to facilitate the sharing of information about multiple uses of the marine environment.  In the U.S. an important component of MSP is...

  • The Economic Impacts of Emerging Diseases in Shrimp Aquaculture: Insights from a Multi-Year, Global Survey of the Industry

    Creator:
    Valderrama, Diego, Anderson, James, and Jory, Darryl
    Abstract:
    Acute hepatopancreatic necrosis disease (AHPND), initially referred to as early mortality syndrome (EMS), is an emergent bacterial disease that has resulted in substantial economic losses for the global shrimp farming industry.  Its occurrence was first reported in China in 2009, rapidly spreading to Vietnam, Malaysia, Thailand, and eventually Mexico in...

  • Fisheries Subsidies: Why Should You Care About Them?

    Creator:
    Sumaila, U. Rashid
    Abstract:
    The objective of this paper is to provide an analysis of the current state of fisheries subsidies worldwide, and how they are likely to affect the sustainability of fisheries. More specifically, I will review previous investigations of global subsidies issues, and give a brief overview of the impact of subsidies...

  • 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...

  • Determinants of Efficiency in a Mixed Fishing Fleet: A Mexican Case Study

    Creator:
    Salas-Márquez, Silvia, Quijano-Quinones, Daniel, and Monroy-García, Carmen
    Abstract:
    Influence of the Skipper Effect in fishing efficiency of a mixed fishing fleet, looking at a Mexican case study. Understanding the factors that define technical efficiency in a fleet is a requirement to define strategies to regulate the fishing pressure. In industrial and semi-industrial fleets more weight has been given...

  • Impacts of the 2008-2009 US West Coast Salmon Ocean Fishery Closure on Salmon Troll Vessels

    Creator:
    Richerson, Kate and Holland, Dan
    Abstract:
    As anthropogenic changes interact with natural climate cycles, the variability of marine ecosystems is likely to increase. This variability influences the behaviour of fishers, which can affect the profitability and sustainability of stocks and may have wider economic and ecological effects. We use data from the US West Coast salmon...

  • An Iterated Multiyear Simulation Model to Assess Impacts of Halibut Bycatch Limits

    Creator:
    Hartley, Marcus
    Abstract:
    Bering Sea/Aleutian Islands (BSAI) groundfish fisheries are hugely productive with 2008 – 2014 harvests averaging 1.6 million tons and generating $1.95 billion annually. The BSAI also hosts a commercial halibut fishery with 2013 landings of 3,500 tons and revenues of $41.5 million. Downward trends in halibut biomass combined with continued...

  • The Economic Cost of Ignoring Fishery Induced Evolution

    Creator:
    Faig, Amanda D.
    Abstract:
    Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....

  • Prospects for Management Reform in Gulf of Mexico Recreational Fisheries

    Creator:
    Willard, Daniel and Abbott, Joshua K.
    Abstract:
    Recreational fishing for popular species like red snapper and grouper in the Gulf of Mexico follows a pattern that is well known in commercial fisheries: fishing under regulated open access promotes short, unpredictable seasons, shrinking bag limits, and large and persistent overharvests. With federal fishing seasons at all-time lows and...
