  • Evaluating an Experimental Catch Shares Program for Gulf of Mexico Headboats: Year One

    Creator:
    Abbott, Joshua K. and Willard, Daniel
    Abstract:
    Recreational fishing for popular species like red snapper and grouper 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 fishery...

  • 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...

  • On the Efficiency of Polish Fishing Fleets

    Creator:
    Hutniczak, Barbara and Münch, Angela
    Abstract:
    The Baltic fishery is managed under the European Union Common Fisheries Policy (CFP) which defines procedures for setting annual total allowable catches (TAC) for major commercially harvested species. TACs are given as fixed shares to each member state by applying the principal of relative stability. Poland uses non-tradable individual vessel...

  • On the Appropriate Rate of Discount

    Creator:
    Arnason, Ragnar
    Abstract:
    Discount rates, it is well-known, play an important role in the determining optimal extraction paths for natural resources. In fisheries analysis, as well as other natural resource use, constant discount rates are customarily assumed. In practical applications, the constant discount rate is often taken to be the social rate of...

  • Trends in Fish Price Volatility: Icelandic Whitefish

    Creator:
    Jonsson, Erlendur, Dahl, Roy Endré, and Asche, Frank
    Abstract:
    For centuries, the Icelandic people has relied on its abundance of natural resources and fisheries in particular. In today’s volatile and homogenous economy of Iceland, fisheries is one of its main export industries, together with power-intensive manufacturing and tourism. Consequently, movements in fish prices have a significant effect on the economy...

  • Fishermen, Markets, and Population Diversity

    Creator:
    Jardine, Sunny and Sanchirico, James N.
    Abstract:
    Fishing impacts biodiversity on multiple levels, potentially resulting in unintended feedbacks to economic performance of the fishery over time. For example, targeting observable traits within a population can impact genetic diversity, targeting populations within a species can impact population diversity, and targeting valuable species can impact biodiversity at the ecosystem...

  • Economic and Biological Consequences of Applying a Constant Catchability Value in a Sequential Fishery

    Creator:
    Aranceta-Garza, Fernando, Arreguín-Sánchez, Francisco, and Seijo, Juan Carlos
    Abstract:
    The Mexican shrimp fishery comprises a sequential fishery: an inshore fleet (IF) using cast nets and targeting juvenile shrimps; and the offshore fleet (OF) using trawler boats targeting adult shrimps. The main target species are brown, blue and white shrimps. Conventional aged-structured models are used to advice management of this fishery...

  • The Cost of Avoiding Sea Cucumber Stock Depletion

    Creator:
    Hernández-Flores, Alvaro, Cuevas-Jiménez, Alfonso, and Aranda-Nah, Javier
    Abstract:
    In 2013 a stock of sea cucumber (Isostichopus badionotus) was discovered in northern shelf of Yucatan. A survey calculated a biomass of 17,600 tons. The species has an attractive price for local fishers, therefore, in order to avoid the “race for sea cucumbers” and the collapse of the stock, authorities...

  • The Price of Lobster, Forecasts and Simulation in a ARDL- Bounds Testing Framework

    Creator:
    Gordon, Daniel
    Abstract:
    Economists have long been interested in empirically modelling/forecasting the price of staple commodities using both structural and reduced form models. The purpose of this paper is to apply Pesaran’s Autoregressive Distributed Lag/ Error-Correction Bounds model for forecasting the ex-vessel price of lobster on the east coast of Canada using monthly...

  • 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....
