Fisheries management. 2. The ecosystem approach to fisheries. 2.1. Best practices in ecosystem modelling for informing an ecosystem approach to fisheries

Abstract

Awareness of the limitations of a single-species approach to fisheries management has led to global acceptance of the need to adopt a wider ecosystem approach to fisheries (EAF) assessment and management. Applying EAF in management requires the application of scientific methods and tools that also go beyond the single-species approaches which used to be, to a large extent, the exclusive sources of scientific advice. Managers and decision-makers must now find management solutions that take into account the wider range of societal objectives that must be explicitly considered under EAF and the interactions in the ecosystem. Ecosystem models, i.e. models that represent a wider range of technological and ecological processes affecting the species in the ecosystem (including multispecies and whole ecosystem models), are potentially important tools for providing this wider scientific information.
