Ecosystem based fisheries management- Winter School on Towards Ecosystem Based Management of Marine Fisheries – Building Mass Balance Trophic and Simulation Models

摘要

A lot of attention has recently been directed at assessing the impacts of fisheries on wholeudmarine ecosystems (ICES, 1998, 2000; Frid et al., 1999b; Hall,1999a,b).This has in partudbeen driven by the need to ensure conservation of biological diversity and sustainable useudof the biosphere, key provisions of the convention agreed at the UN Rio summit (Tasker etudal .,2000).The utilization of sound ecological models as a tool in the exploration andudevaluation of ecosystem health and state, has been encouraged and endorsed by the leadingudbodies in ecosystem-based fisheries research and management (NRC,1999; ICES, 2000).udThe potential of the available dynamic ecosystem models to make measurable andudmeaningful predictions about the effects of fishing on ecosystems has not however beenudfully assessed.
