Despite some spectacular failures (e.g., Peruvian anchoveta), the total landings of marine fisheries continue to increase slowly, but the economic losses through mismanagement — overcapacity with ac

Biophilia: Need for Contact with Nature,This paper considers evidence from ecological theory and observation relevant to the response of multispecies marine communities to exploitation. The problems of reversibility, multiple stable states, and the differences between complex and simple communities are reviewed.

Some entrepreneurs thrive successfully in the most uncertain circumstances, and the existence of futures markets and insurance companies indicates that others are prepared to pay to avoid carrying the burden of uncertainty.

Fictions: subverting the stereotypes,ch attention from one species to another vary. The fisheries off northwest Africa are reviewed as an example of a multispecies, multi-fishery system. Examples are given of systems in other regions. The impact of having to deal with a multispecies, rather than a single-species situation, on the different stages of fishery management is discussed.
