  • The Economics of Overexploitation Revisited

    Creator:
    Grafton, R. Quentin, Kompas, Tom, and Hilborn, Ray
    Abstract:
    About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). Using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the...

    Abstract:
    The existence of excessive fishing capacity is globally recognized by resource managers as a major problem for fisheries, which is responsible for the degradation of fishery resources and for significant economic waste. Lately, the measurement of fishing capacity and capacity utilization has become more important due to the various national...

  • Role Of Institutions With Regard To Fisher Livehoods And Resource Conservation: Small-Scall Craff Fishery in Sri Lanka

    Creator:
    Withana Arachchige, Ranjith Wickramasinghe and Bavinck, Maarten
    Abstract:
    This paper identifies economic institutions related to the small-scale craft fishery in southern Sri Lanka, and assesses their importance for the livelihood of the fisher households as well as for resource conservation. Income from small-scale craft fishing is generally uncertain because of seasonality and uncertainty of the marine fish resource,...

  • Creation of Marine Reserve and Incentives for Biodiversity Conservation

    Creator:
    Quach, Thi Khanh Ngoc
    Abstract:
    Recently the ecosystem based management have been dealt with in management as a useful approach for fisheries. The goal of ecosystem-based management are sustainable management of fisheries and other marine resource through establishment of well-managed network of marine protected areas. Despite a number of benefits from marine reserve such as...

  • A Bioeconomic Model of Fishery-Habitat Impacts

    Creator:
    Kahui, Viktoria and Armstrong, Claire
    Abstract:
    A scientific knowledge gap exists with regard to how benthic habitat is affected by destructive fishing methods, such as bottom trawling, and how this impacts upon the productivity of commercial fish stocks. This article addresses analytically the effects of destructive fishing practices of a single gear fishery on a non-renewable...

  • Diversifying Artisanal Fishing Fleets in the Galapagos Marine Reserve

    Creator:
    Larkin, Sherry and Adams, Charles
    Abstract:
    Fishing activities within the Galapagos Marine Reserve (GMR) are restricted to small-scale levels by national law. The fishing sector has relied on just two fisheries, sea cucumber and spiny lobster, and a strong Asian export market. Despite a series of input and output controls and a co-management scheme, stocks have...
