Experience with quantitative ecosystem assessment tools in the northeast Pacific

摘要: We consider the question of which quantitative modelling tools can be used to support an ecosystem approach management (EAM), with a focus on evaluating implication decisions biological system being managed. Managers federal fisheries in eastern Bering Sea, USA, have adopted EAM. The EAM Sea serve as guide what types models could elsewhere. A review role natural science implementation shows that scientific advice enters into decision-making at variety steps. Single-species stock assessment and projection are most commonly employed inform managers.
