Abstract:: The World Summit on Sustainable Development (Johannesburg, 2002) encouraged the application of the ecosystem approach by 2010. We propose a framework that deals jointly with i) ecosystem dynamics, ii) conflicting issues of production and preservation and iii) robustness with respect to dynamics uncertainties. More specifically, we define robust viability kernels...

Abstract:: We assess cod, herring, and sprat fisheries in the Baltic Sea under different salinity conditions using a bioeconomic model with simple predation functions. We compare the current fishing policy to an optimal policy under two different salinity conditions, which have a link to climate change. The fishery of these species...

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:: The aim of this work is to develop a predator-prey model for two species of commercial importance captured by the Spanish fishing fleet in the National Fishing Ground (ICES areas VIIIc and IXa). In this model, the Southern hake (Merluccius merluccius) represents the predator, and the blue whiting (Micromesistius poutassou)...

Abstract:: The objective of this paper is to study the economic management of Eastern Baltic cod (Gadusmorhua) under the influence of nutrient enrichment. Average nitrogen concentration in the spawning areas during the spawning season of cod stock is chosen to be an indicator of nutrient enrichment. The optimal cod stock is...

Abstract:: Major fishery investment has recently been implemented in West Africa as part of the World Bank's West Africa Regional Fisheries Program. To support this effort the New Partnership for Africa's Development funded development of a Seafood Bio-Economic Assessment Model. The model was initially developed for Ghana, but will accommodate other...

Abstract:: In the Baltic Sea, the successful conservation of grey seals has increased seal-induced damages to the Atlantic salmon fishery. The paper addresses the conflict between the conservation of the formerly endangered species and professional fishermen whose livelihood is also regulated by fisheries management. We develop a bioeconomic model that accounts...
