  • BC-to-Alaska Transboundary Salmon: Conflict, Enhancement, Moral Hazard, Paper-Fish and Folly

    Creator:
    Wright, Christopher Stephen and Gould, Robert
    Abstract:
    Enhancement of British-Columbia-to-Alaska Transboundary Rivers is a vast potential prize to all concerned. However, despite funding commitments in the Pacific Salmon Treaty, that program is at great risk of always being more potential than real. The cooperation needed to make this program work has been and continues to be grievously...

  • 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....

  • Bioeconomic Modelling of the Namibian Rock Lobster

    Creator:
    Steenkamp, Z. D.
    Abstract:
    The purpose of this study is aimed at developing a simple bioeconomic model of the Namibian rock lobster fishery, with the main objective being to incorporate economics into fisheries management in order to estimate the potential economic benefits that could accrue to the fishery given efficient management. The complex nature...

  • Are Catfish Inspections an Administrative Trade Barrier to Imported Fish?

    Creator:
    Davidson, Kelly and Kropp, Jaclyn D.
    Abstract:
    The Agricultural Act of 2014 (Public Law 113-79) amended legislation regarding the U.S. catfish inspection program to include “all fish of the order Siluriformes,” encompassing imported species: basa, tra, and pangasius. Furthermore, the amendment finalized the transition of catfish and catfish-like product inspection responsibilities to the USDA Food Safety and...

  • Estimating a Generalized Gordon-Schaefer Model with Heterogeneous Fishing Data

    Creator:
    Zhang, Junjie and Smith, Martin D.
    Abstract:
    This paper proposes a two-stage method to estimate a generalized Gordon-Schaefer model, using heterogeneous fishing data in the logbook. A Cobb-Douglas production function is consistently estimated in the first stage by means of the ‘within period estimator’. A stock index is constructed and used to estimate the logistic growth model...

  • Discrete Choice Modeling of Landings Locations

    Creator:
    Asche, Frank, Smith, Martin D., and Birkenbach, Anna
    Abstract:
    Interest in sustainable fishing communities suggests the need to understand fishermen’s decisions about where to land fish. In this paper, we apply techniques used extensively to analyze fishing location choices to study landings location choices. We analyze detailed microdata from Norwegian groundfish vessels that land fish in fourteen different ports...

  • State Dependence in Modeling the Spatial Behavior of Renewable Resource Users

    Creator:
    Smith, Martin D. and Wilen, James E.
    Abstract:
    In marine resource management, spatial policy instruments, including Marine Protected Areas, are becoming increasingly important. The economic motivation for spatially explicit policy is that renewable resources generate, in addition to the conventionally recognized incentives to over-harvest in the face of insecure property rights, spatial externalities that distort the spatial distribution...

  • The Effects of Derelict Gear on Blue Crab Production in the Chesapeake Bay

    Creator:
    Scheld, Andrew M., Bilkovic, Donna M., and Havens, Kirk J.
    Abstract:
    Several factors currently threaten blue crab (Callinectes sapidus) in the Chesapeake Bay. In addition to poor water quality, degraded habitat, and shifting environmental conditions, derelict gear has recently been recognized as a significant source of mortality for this economically and culturally significant species. From 2008 through 2014, commercial watermen in...
