Creator:: Quezada, Felipe, Luzardo, Ivan, Dresdner, Jorge, and Pena-Torres, Julio
Abstract:: This paper analyses evidence about fishermen collectively organized bargaining over ex-vessel prices with a monopsony-like buying sector. Government allocation of collective catch quotas to fishermen organizations triggered the voluntary formation of cooperative fishermen’s bargaining associations, while a highly concentrated processing sector started behaving as a countervailing monopsony. This drove ex-vessel...

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...

Creator:: Coglan, Louisa and Pascoe, Sean
Abstract:: Fishers are faced with multiple risks, including unpredictability of future catch rates, prices and costs. While the latter are largely beyond the control of fisheries managers, effective fisheries management should reduce uncertainty about future catches while also enhancing profitability. Different management instruments are likely to have different impacts on the...

Abstract:: The wide expanse of the sea, the inter-linkages among, and the productivity of its resources have until recently led most researchers to consider it unrealistic that humans could have more than local impact on marine ecosystems and their biodiversity. This perception is changing, however, as more evidence of the scale...

Creator:: Brandt, Urs Steiner and Kronbak, Lone Grønbæk
Abstract:: Many international fisheries agreements involve sharing rules. These rules are normally stable rules, not contingent on shifts in the relative distribution or development of the resource. In the latest IPCC report, the most likely future scenario is an increase in the global mean temperature, and most severely in high latitudes....

Abstract:: ICES – the International Council for the Exploration of the Sea – was founded more than a century ago out of concern for overfishing. However, today’s global marine ecosystems are for the most part in a degraded state, many alarmingly so. Why is the science used so little to make...

Creator:: Nashandi, Wilbard
Abstract:: The open access nature of fisheries resources had caused application of excessive fishing effort to most World fisheries. Proper management of fisheries resources is vital for sustainability and its safe future utilisation. Most attempts to salvage fisheries resources had so far succeeded but have also created one or more problems....

Creator:: Steinmetz, Fabien, Thebaud, Olivier, Guyader, Olivier, and Blanchard, Fabian
Abstract:: Recent work in the domain of fisheries ecology has shown that major changes are occurring in fish communities exploited by commercial fisheries. Selective fishing pressure on more highly valued components of fish communities, and its indirect effects via trophic interactions, are amongst the key factors proposed to explain these changes....

Abstract:: Substitution and elasticity give about the history of supply and the demand structure for fish and seafood. It is also relevant to the detection of change in a particular exploited marine ecosystem. The purpose of this paper is to test if market elasticity of substitution of seafood categories can further...

Creator:: Martinet, Vincent, De Lara, Michel, Peña-Torres, Julio, and Ramirez, Héctor
Abstract:: This paper develops a theoretical framework to assess resources management procedures from a sustainability perspective, when resource dynamics is marked by uncertainty. Using stochastic viability, management procedures are ranked according to their probability to achieve economic and ecological constraints over time. This framework is applied to a fishery case-study, facing...
