  • Market Interaction Between Tilapia Imports and US Catfish Production

    Creator:
    Norman-López, Ana
    Abstract:
    Tilapia exports to the US have been claimed to double in the last three years following the two bans on Vietnamese catfish imports in November 2001 and June 2003. The aim of these bans was to restrict imports from the major exporter of Catfish (Vietnam) reducing competition for US catfish...

  • Structural breaks in the fishmeal - soybean meal price relationship

    Creator:
    Kristofersson, Dadi and Anderson, James L.
    Abstract:
    The rapid increase in global aquaculture production since the early nineties has increased the demand for fishmeal as an ingredient in aquafeed. This increase has been hypothesized as the source of disruption in the fishmeal market by researchers such as Delgado et al. In this paper we evaluate whether or...

  • Integration and Causality in Demand: Farmed Trout in Germany

    Creator:
    Nielsen, Max, Setala, Jari, Laitinen, Jukka, Saarni, Kaija, Virtanen, Jarno, and Honkanen, Asmo
    Abstract:
    In this paper, a new test for causality in demand on markets supplied by both farmed and captured fish is presented. This method is applied on markets for trout and potential substitutes imported to Germany, to identify market delineation and causality in demand. It is found that markets for small...

  • Using Real Options to Estimate a Benefit of The Adaptive Resource Management

    Creator:
    Makino, Mitsutaku
    Abstract:
    In the institutional framework of fishery management in Japan, which can be seen as a Co-Management system, fishermen's agreements are prerequisites for implementation of resource management measures. However, because of uncertainties in the effect of management measures, fishermen's agreements are difficult to obtain. This study applied a decision-making method under...

  • Price Transmission in Cross Boundary Value Chains

    Creator:
    Asche, Frank, Menezes, Rui, and Dias, Joao Ferreira
    Abstract:
    The extent to which demand and supply shocks are transmitted in the value chain is an important topic. As many value chains cross international borders exchange rate pass through is an important element in this context. In this paper a multivariate system that allow us to test different hypothesis with...

  • The Relationship between Fisheries and Farming

    Creator:
    Kristofersson, Dadi, Shamshak, Gina Louise, and Anderson, James L.
    Abstract:
    Fishmeal is a critically important feed ingredient for use in animal (e.g., poultry and pork) and aquaculture production (e.g., salmon, trout, and shrimp). There is concern that demand for fishmeal may place additional stress on the world’s pelagic fisheries and may undermine the sustainability of some aquaculture systems that rely...

  • Observing Recovery: The Role of Implicit Discount Rates in ITQ Fisheries

    Creator:
    Batstone, Chris and Sharp, Basil
    Abstract:
    This paper discusses the potential application of implicit discount rates (IDR) derived from Individual Transferable Quota (ITQ) trading data as indicators of fishery bio-economic health. The theoretical background is discussed, and in the context of one New Zealand ITQ fishery we analyze the behavior of IDR over ten years of...

  • Price Relationships on the Spanish Hake Market

    Creator:
    Guillen, Jordi, Franquesa, Ramon, and Sole, Ignasi
    Abstract:
    The Spanish market is the most important market for hake and hake has been for many years the demersal fish most captured in Spain. To the traditional product differentiation due to size, gear and presentation form (fresh, frozen and frozen fillets), a new differentiation can be performed regarding the hake...

  • The Fishery as Economic Base in the Newfoundland Economy

    Creator:
    Roy, Noel, Arnason, Ragnar, and Schrank, William E.
    Abstract:
    Historically, the fishery has been the mainstay of the Newfoundland economy. Inevitably, its importance declined as economic development proceeded, but was still quite substantial at the time of Confederation with Canada in 1949. Since then, however, the census figures show a precipitous decline in the role of the fishery in...
