  • Climate Change and Productivity in the Aquaculture Industry

    Creator:
    Lorentzen, Torbjørn
    Abstract:
    Global warming is expected to affect the ecosystem in the Northeast Atlantic, and sufficient changes will also affect the aquaculture industry. Farming of salmon and trout is the biggest aquaculture industry in Norway. The export value was about 2 billion US dollars in 2005. The objective of the paper is...

  • On the Joint Management of Catch and Bycatch and the Use of Marine Reserves

    Creator:
    Reithe, Siv
    Abstract:
    This paper explores the possibility of using marine reserves to protect stocks subject to bycatch problems. The importance of migration rates and growth rates of both target and bycatch species and costs are analyzed. Pure open access equilibrium harvest of target species and stock level of bycatch species are compared...

  • Growing the seafood sector: Technical change and innovation

    Creator:
    Sharp, Basil and Jeffs, Andrew
    Abstract:
    The scope for fishing firms operating in an output controlled fishery, with tradable rights, and facing world prices, to augment profit is limited inter alia to a search for alternative input configurations that lower harvesting costs. This paper provides evidence of technical change in the New Zealand rock lobster fishery....

  • Putting Fisheries and Aquaculture on Nepad Agenda

    Creator:
    Williams, Stella B., Heck, Simon, Chimatiro, Sloans, and Gordon, Ann
    Abstract:
    Capture fisheries is a primary employment for inhabitants of coastal and inland aquatic ecosystems globally. However, historically, aquaculture has been well documented as an economic activity in Southeast Asia. Coastal marine fisheries and freshwater inland waters provided employment for inhabitants of these ecosystems in Sub-Saharan Africa (SSA). Aquaculture was started...

  • Aquaculture-Fisheries Interactions

    Creator:
    Mikkelsen, Eirik
    Abstract:
    Assuming externalities from aquaculture to fisheries, we use a Verhulst-Schaefer model of fish population-dynamics and production, coupled with an aquaculture production model, to investigate effects on open-access and rent-maximising fisheries. Externalities are modelled by letting carrying capacity, intrinsic growth rate or catchability coefficient in the fishery depend on aquaculture production....
