Reconciling biodiversity conservation and marine capture fisheries production

Abstract

Pathways for moving towards the goals of biodiversity conservation and food security in terrestrial systems include the application of trait-based ecology to develop highly productive agroecosystems with less negative effects on biodiversity. Although marine ecosystems have been impacted by human activity over several centuries, the changes have been unintentional and undirected; we have not learned how to enhance food production from the sea and are reliant, as hunter-gatherers, on natural production. The goals of maximising fisheries production and maintaining biodiversity may be difficult to achieve simultaneously, but studies of marine ecosystem responses and models of multispecies interactions provide a basis for new ecosystem approaches.
