Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is a candidate for reinvention, with many world leaders in this area holding the view that no fishery has ever been properly understood or managed. This study seeks a new paradigm that will place the flux of ideas in perspective and help to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: why does fisheries science need reinventing?; new policies; the role of the social sciences; ecology; modelling.
