Abstract:: The paper puts forward a model of the Pearl River Delta (PRD) fishery in the South China Sea that integrates the ecological, social and economic costs and benefits of fisheries activities in a multidisciplinary framework. In particular, In particular, we developed integrated model by linking a regional Social Accounting Matrix...

Creator:: Christensen, Villy, Villanueva, Maria Concepcion, and Aiken, Karl A.
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...

Full Text:: 1 ECOSYSTEMS AT RISK: THE CONTRIBUTION OF ECOSYSTEM APPROACHES TO FISHERIES TO IDENTIFY PROBLEMS

Creator:: Ravn-Jonsen, Lars, Andersen, Ken H., and Vestergaard, Niels
Abstract:: Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...

Full Text:: An Indicator for Ecosystem Externalities in Fishing Lars J. Ravn-Jonsen∗, Ken Haste Andersen

Creator:: Abbott, Joshua K. and Fenichel, Eli P.
Abstract:: Fisheries sustainability is a much sought-after goal. Yet, “sustainability” is often too ambiguously defined to be of much practical guidance to policymakers. Furthermore, fisheries managers are increasingly expected to assess and manage fisheries in an “ecosystem-based” manner – accounting for the ecological interdependencies of species and their coupling with the...

Full Text:: Comprehensive Fishery Wealth: A Bioeconomic, Ecosystem- Based Approach to Measuring Fisheries Sustainability

Creator:: Hutniczak, Barbara
Abstract:: Multispecies fisheries pose a considerable management difficulty with respect to quota allocation between species. Externalities of direct control over the harvest may include, among others, creation of unbalanced predator‐prey relationships in the environment. That, in turn, may affect the individual economic incentives of fishing vessels. Combining economic and ecological factors...

Creator:: Le Floc'h, Pascal, Thébaud, Olivier, Amrani, Mohammed, Blanchard, Fabian, Chaboud, Christian, Malouli, Mohammed, and Maski, Hicham
Abstract:: This paper addresses to a comparative approach of long term changes in the characteristics of marine fisheries at a regional scale, in three ecosystems: up-welling, tropical and temperate. The South Moroccan continental shelf, under the influence of the Canary current, where up-wellings take place, is the most productive part of...

Abstract:: Maryland, Pennsylvania, Virginia, and West Virginia have all developed nutrient trading programs to defray the cost of achieving mandated nitrogen load reductions in Chesapeake Bay, and there is increasing interest in the role oysters can play in generating credits. A number of bioeconomic models highlight the impact these credits have...

Creator:: Poudel, Diwakar and Steinshamn, Stein Ivar
Abstract:: This study investigates optimal catch of Barents Sea stocks, namely Northeast Arctic Cod and Capelin in multispecies ecosystem. We solve a multispecies age structured bioeconomic model for predator-prey interaction. Barents Sea stock data from ICES are employed for model application. Among others, we also include sustainability constraint in the model...

Abstract:: Earlier this year a White Paper from the Norwegian Minister of the Environment presented a new, holistic, area-based management plan for the Norwegian part of the Barents Sea, including the Fishery protection zone around Svalbard. The plan will provide guidelines for managing human activities in relation to their use and...
