  • Current and Potential Fish Asset Values Worldwide

    Creator:
    Sumaila, Rashid
    Abstract:
    The World Bank has constructed wealth accounts for nearly 15 years, most recently in The Changing Wealth of Nations. The accounts include produced capital, natural capital and human and social capital. Natural capital includes agricultural land, forests, subsoil assets and protected areas, but omit a number of critical natural capital...

  • Fisheries Subsidies: Why Should You Care About Them?

    Creator:
    Sumaila, U. Rashid
    Abstract:
    The objective of this paper is to provide an analysis of the current state of fisheries subsidies worldwide, and how they are likely to affect the sustainability of fisheries. More specifically, I will review previous investigations of global subsidies issues, and give a brief overview of the impact of subsidies...

  • Are Small-scale Fisheries Economically Viable?

    Creator:
    Sumaila, Rashid and Hotte, Ngaio
    Abstract:
    The contributions of small-scale fisheries to income and employment are well recognized but not sufficiently understood. It is difficult to gauge, for instance, whether this sector is economically viable, especially in the context of large-scale economic, social, political, and ecological change processes. These knowledge deficits create an environment of uncertainty...

  • Climate Change Effects on the Economics and Management of World Fisheries

    Creator:
    Sumaila, Rashid and Hotte, Ngaio
    Abstract:
    Climate and marine ecosystem research informs us that marine fish resources would come under increasing stress over the course of the 21st century as global climate change, ocean acidification and de-oxygenation combine with other stresses on the ocean, including heavy fishing pressure and marine pollution, to change the primary productivity...

  • Economics of Joint Management of the Resources of the Benguela Current Large Marine Ecosystem

    Creator:
    Sumaila, Ussif Rashid, Munro, Gordon, and Keith, Heather
    Abstract:
    This paper is drawn from a project report that was sponsored by the United Nations through the Benguela Current Large Marine Ecosystem Programme. We analyze the economics of fishery management in the Benguela Current Large Marine Ecosystem (BCLME), reviewing the case for and against regional co-operation in managing the BCLME....

  • Estimating Costs of Sea Lice from Salmon Aquaculture on Wild Salmon Fisheries

    Creator:
    Liu, Yajie, Volpe, John, and Sumaila, Ussif Rashid
    Abstract:
    Sea lice are natural parasites, and are spread between wild salmon stocks and farmed salmon. Studies indicate that sea lice from salmon farms not only cause economic losses to salmon aquaculture producers, but also affect other marine resources. Currently one of the most controversial debates over sea lice from salmon...

  • Global Ex-Vessel Fish Price Database: Construction and Applications

    Creator:
    Sumaila, Ussif Rashid, Marsden, A. Dale, Watson, Reg, and Pauly, Daniel
    Abstract:
    We describe the first effort at creating a global ex-vessel fish price database. We then demonstrate potential applications of the database by linking it to the Sea Around Us project's spatially defined catch database, which makes it possible to attach catch values to species both in time and space. There...

  • The Economic Viability of Small- vs. Large-Scale Fisheries: An Example from Mexico

    Creator:
    Schuhbauer, Anna, Cisneros-Montemayor, Andrés, and Sumaila, U. Rashid
    Abstract:
    Achieving economic viability is an important goal when it comes to developing policies for sustainable fisheries management, especially for small-scale fisheries (SSF). SSF are vital for many coastal communities, however, often economically and politically marginalized. Here, we develop and estimate what we denote as ‘basic economic viability’ of SSF, using...

  • Marine Reserves and Quotas as Fisheries Management Tools: When does Marine Reserve Creation Pay?

    Creator:
    Reithe, Siv
    Abstract:
    This paper explores the issue of using marine reserves in combination with quotas as fisheries management tools. The underlying biological dynamics are described by a patchy environment model, in which a metapopulation is built up by linked sub-populations that are distributed across a set of spatially discrete habitats or patches....

  • A Model of Fishing Conflicts in Foreign Fisheries

    Creator:
    Wachsman, Yoav
    Abstract:
    Coastal nations can impose conditions of use on foreign fishing firms that operate in their Exclusive Economic Zone. We develop a game-theoretical model in which a fishery owner maximizes the revenue that it collects from firms that operate in its EEZ by charging them a fishing fee. We find that...
