  • U.S. Catfish Farm Supply Under Uncertainties

    Creator:
    Nguyen, Giap and Jolly, Curtis M.
    Abstract:
    The present study uses normalized profit function and adaptive expectation approaches to analyze U.S. catfish farm supply. Empirical estimations give short-run supply elasticity of 0.25 and 0.26 and long-run supply elasticity of 0.47 and 2.1 in each of the two approaches, respectively. Technological improvement is attributed for only 9.8% out...

  • Modeling the Asian Fish Sector: Issues, Framework, and Method

    Creator:
    Dey, Madan M., Briones, Roehlano M., and Ahmed, Mahfuzuddin
    Abstract:
    The paper presents a detailed approach to modeling supply and demand of the Asian fish sector. It discusses the salient features of the fish sector in Asian countries that need to be incorporated in a comprehensive model of fish supply and demand, as well as the usefulness of supply and...

  • Individual Transferable Quotas in a Household Economy: Will The System Work?

    Creator:
    Uchida, Hirotsuga, Wilen, James E., and Larson, Douglas M.
    Abstract:
    This paper analyzes the behavior of fishing households under individual transferable quotas (ITQ) system based on Singh, Squire and Strauss household model. ITQ system is sought to be the optimal fishery management regime in terms of economic efficiency. However, preceding theoretical analyses only considered implementing ITQ to a well established...

  • Considerations for TAC Targets in a Single Gear, Multiple Species Fishery

    Creator:
    Nam, Jongoh, Ryu, Jeong-Gon, and Gates, John M.
    Abstract:
    This paper provides a Total Allowable Catch (TAC) assessment model for a single gear, multi-species fishery in South Korea. To estimate appropriate Allowable Biological Catch (ABC) of mackerel and jack mackerel caught by the large purse seine fleet in the territorial waters of South Korea, the model uses an extended...

  • Coastal Aquaculture Development in Bangladesh: Un-sustainable and Sustainable Experiences

    Creator:
    Azad, Abul Kalam, Lin, C. Kwei, and Jensen, Kathe R.
    Abstract:
    Coastal aquaculture in Bangladesh mainly consists of two shrimp species (Penaeus monodon and Macrobrachium rosenbergii). Currently, there are about 16,237 marine shrimp (P. monodon) farms covering 148,093 ha and 36,109 fresh water shrimp (M. rosenbergii) farms covering 17,638 ha coastal area. More than 0.70 million people are employed throughout the...

  • Adoption and Economics of Tilapia Farming Technology in the Philippines

    Creator:
    Sevilleja, Ruben
    Abstract:
    This paper examines the circumstances under which farmers respond to the introduction of tilapia production technology, and analyzes the manner in which the benefits from such introduction are shared and distributed among recipients. The hypothesis that the inverse relationship between yields and operational land size widely observed in agriculture is...

  • Economic Efficiency in the Coastal Small-scale Fisheries in Lagos State, Nigeria

    Creator:
    Jinadu, Olujimi O.
    Abstract:
    This study was aimed at assessing how efficient the small - scale fishing units in Lagos State, Nigeria use the monetary inputs: costs of gear repairs, craft repairs, fuel, fishing losses, hired labor, and the residual costs of craft and gear. Between January and December, 113 mechanized and 43 non-mechanized...

  • Fisheries Management Costs in Thai Marine Fisheries

    Creator:
    Willmann, Rolf, Boonchuwong, Pongpat, and Piumsombun, Somying
    Abstract:
    The paper first introduces the fisheries management dilemma faced by many Asian developing countries including Thailand and the key elements of a transition policy towards responsible fisheries. It then analyses current fisheries management costs in Thai marine fisheries. Major cost items include fisheries research (especially stock assessment), monitoring, control and...

  • Fisheries Rents: Theoretical Basis and an Example

    Creator:
    Arnason, Ragnar
    Abstract:
    The concept of natural resource rents is much used in the natural resource and fisheries economics literature. It is therefore somewhat surprising that in this same literature it is difficult to find a clear definition of either natural resource rents or fisheries rents. Possibly, as a result, the concept is...

  • The mixed bless of modern fishing technology

    Creator:
    Skonhoft, Anders
    Abstract:
    This paper formulates a simple biomass growth model of a fishery. The property rights regime is of the unregulated local common property type with a fixed number of fishermen and where the fish stock is exploited in a myopic profit-maximizing manner. Within this resource management setting it is demonstrated that...
