  • Growth Overfishing

    Creator:
    Diekert, Florian K.
    Abstract:
    Growth overfishing squanders large parts of the potential rents in fisheries. Many of today’s fisheries are characterized by a severely truncated age-distribution, which in addition may have irreversible ecological consequences. Nevertheless, the implications of age-differentiated harvesting for management have received surprisingly little attention in the literature. In the present paper,...

  • Faustmann in the Sea Optimal Rotation in Aquaculture

    Creator:
    Guttormsen, Atle G.
    Abstract:
    In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...

  • Open Access Performance When Vessels Use Profit Goal Behavior

    Creator:
    Anderson, Lee G.
    Abstract:
    While most bioeconomic models assume that vessel operators use profit maximizing behavior, it is sometimes argued that participants use other operational goals. The purpose of this paper is to compare how vessel behavior, the bioeconomic equilibrium and the path to achieve it are changed if participants use profit goal behavior....

  • Marine Reserves: a Closer Look at What They Can Accomplish

    Creator:
    Anderson, Lee G.
    Abstract:
    The presents a theoretical analysis of the operation of a commercial fishery in the presence of marine reserves. The sustainable yield and revenue curves for reserves are derived and compared to the analogous curves with no reserves. It is shown that reserves will always reduce the sustainable harvest for any...

  • A Modelling Approach to Estimate the Economic Benefits of Intervention for Disease in Aquaculture

    Creator:
    Murray, Alexander G. and Hall, Malcolm
    Abstract:
    A quarter of biomass losses in Scottish marine Atlantic salmon aquaculture are attributable to infectious disease. Interventions to reduce the consequences of disease include the use of disease-resistant stock, vaccines and other authorised medicines, functional feeds, and modified farm management strategies. There are, however, only a few evaluations of the...

  • Developing Case Studies for Fishery Management Training

    Creator:
    Jodice, Laura and Brown, Lew G.
    Abstract:
    The top business management educators consider case teaching to be a highly effective means for building critical decision-making skills in future managers. Although this method holds significant potential, it is not commonly used in fisheries management education and training. The Training Mangers for 21st Century Fisheries Initiative has identified development...

    Creator:
    Abu Hena, Mustafa Kamal, Hishamuddin, O., Misri K., and Faridah A.
    Abstract:
    The growth of tiger shrimp P. monodon and physicochemical factors of pond water and sediment were observed in tropical climate using bacterial products called probiotics. No improvement in shrimp growth and water quality was noted compare to other reported studies. The organic matter (OM) and total sulfur (TS) of pond...

  • Ecolabelling and Small-scale fisheries, will certification work?

    Creator:
    Viswanathan, K. Kuperan and Gardiner, P. R.
    Abstract:
    National and intergovernmental regulation of fisheries has not been sufficient to prevent many failures of fisheries management at the global scale. International trade in fisheries is of the order of USD 10 billion annually, mostly from “South” to “North”. Developing countries, particularly in Asia, benefit from this trade, and domestic...

  • The Economics of Norwegian Salmon Farming: A Review of 30 years of Production Growth

    Creator:
    Rødseth, Kenneth Løvold and Guttormsen, Atle G.
    Abstract:
    Norwegian aquaculture emerged in the end of 1960 when new discoveries transformed production from trout farming to salmon farming. During recent decades farmed salmon has been one of the most successful aquaculture species in terms of production growth. Annual global production has increased from a few thousand tons in 1980...

  • Fuzzy Logic and Non-market Valuation: A Comparison of Methods

    Creator:
    van Kooten, G. Cornelis and Krcmar, Emina
    Abstract:
    In seeking to value environmental amenities and public goods, individuals often have trouble trading off the (vague) amenity or good against a monetary measure. Valuation in these circumstances can best be described as fuzzy—both in terms of the amenity valued, perceptions of property rights, and the numbers chosen to reflect...
