This contribution employs a „fish chain‟ approach or ocean to plate analysis to examine key market drivers affecting Northern Gulf cod fisheries recovery since their collapse in the early 1990s. Drawing upon the backward bending supply model of fisheries; secondary data was compiled and analyzed for the pre- and post-collapse...
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...
Pelagic fish stocks are subject to fluctuations that are driven by climate change, overfishing and changes in market conditions. The fluctuating nature of pelagic fisheries creates uncertainties in fishers’ income, thereby adversely affecting their livelihoods. The aim of this contribution is to reduce the risk and vulnerability fishers face by...
The ocean plays a critical role in supporting human well-being, from providing food, livelihoods and recreational opportunities to regulating the global climate. Sustainable management aimed at maintaining the flow of a broad range of benefits from the ocean requires a comprehensive and quantitative method to measure and monitor the health...
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...
Even in the absence of commercial fishing, Coho salmon (Onchorhynchus kisutch) originating from the Interior Fraser River (IFR) watershed have yet to recover from the low returns experienced since 1992. Coho are in a low productivity regime in which the number of recruits per spawner (R/S) averages around one, coupled...
This paper proposes a game theoretic modeling framework for the assessment of the trade-off between economic efficiency gains and biodiversity conservation in a fishery. It introduces a biodiversity index, and develops an application of the method couched on Namibian hake fisheries. Results from the illustrative example show that the opportunity...
Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...
Proceedings of Visible Possibilities: The Economics of Sustainable Fisheries, Aquaculture and Seafood Trade, the 16th Biennial Conference of the International Institute of Fisheries Economics & Trade, held July 16-20, 2012 in Dar es Salaam, Tanzania.
This paper puts forth the proposition that all catch share schemes should be analysed primarily through the lens of cooperative game theory, which has now been developed to an advanced degree in the analysis of international fisheries management. If the fishers in a catch share scheme are playing cooperatively, the...
