Addressing ecosystem effects of fishing using marine protected areas

ICES Journal of Marine Science ()


This article is a synthesis of the current literature on the potential of marine protected areas (MPAs) a useful management tool for limiting the ecosystem effects of fishing, including biological and socio-economic aspects. There is sufficient evidence that fishing may negatively affect ecosystems. Modelling and case studies show that the establishment of MPAs, especially for overexploited populations, can mitigate ecosystem effects of fishing. Although quantitative ecosystem modelling techniques incorporating MPAs are in their infancy, their role in exploring scenarios is considered crucial. Success in implementing MPAs will depend on how well the biological concerns and the socio-economic needs of the fishing community can be reconciled.Cet article fait la synthese de la litterature sur la possibilite d'utiliser les zones marines protegees (MPAs) comme outils de gestion afin de limiter les effets de la peche sur les ecosystemes, en incluant les aspects biologiques et socio-economiques. La litterature fournit suffisamment d'evidences a l'effet que la peche peut avoir un effet negatif. Les MPAs etablies dans divers habitats a travers le monde ainsi que les modelisations montrent que MPAs offrent une certaine protection contre ces effets negatifs. Les techniques quantitatives de modelisation des ecosystemes, bien que cruciales pour l'exploration de scenarios de gestion, n'en sont encore qu'a leurs debuts et meriteraient encore plus d'attention. Finalement, le succes des MPAs dependra de la maniere dont on reussira a allier les aspects biologiques et les interets socio-economiques.
