N2 - Applying single-species assessment and quotas in multispecies fisheries can lead to overfishing or quota underutilization, becauseadvice can be conflicting when different stocks are caught within the same fishery. During the past decade, increased focus onthis issue has resulted in the development of management tools based on fleets, fisheries, and areas, rather than on unit fishstocks. A natural consequence of this has been to consider effort rather than quota management, a final effort decision beingbased on fleet-harvest potential and fish-stock-preservation considerations. Effort allocation between fleets should not be based onbiological considerations alone, but also on the economic behaviour of fishers, because fisheries management has a significantimpact on human behaviour as well as on ecosystem development. The FcubEcon management framework for effort allocationbetween fleets and fisheries is presented, based on the economic optimization of a fishery’s earnings while complying with stock-preservationcriteria. Through case studies of two European fisheries, it is shown how fishery earnings can be increased significantly byreallocating effort between fisheries in an economically optimal manner, in both effort-management and single-quota managementsettings.Applying single-species assessment and quotas in multispecies fisheries can lead to overfishing or quota underutilization, becauseadvice can be conflicting when different stocks are caught within the same fishery.
