Application of the eco-viability approach for the management of mixed fisheries under output control

Abstract : The thesis contributes to the development of more integrated approaches to advise Total Allowable Catch (TAC) decisions in mixed fisheries by: (1) accounting for technical, but also economic interactions among jointly harvested species, and (2) addressing the variety of sustainability requirements faced in such fisheries. The thesis notably contributes to improving the representation of human dynamics in the type of models used to advise TAC decisions in mixed fisheries, with a particular attention given to the representation of dynamics in the allocation of fishing effort, the trading of individual quotas and fish markets. The thesis also focuses on how the multiple dimensions of sustainability can be considered in the provision of fisheries management advice. The eco-viability approach is used here to identify future paths maintaining a fishery within ecologically, economically and socially acceptable bounds. The developed methodology has been applied to two mixed fisheries operating in different management contexts: the French demersal fishery in the Bay of Biscay and the Australian Southern and Eastern Scalefish and Shark Fishery.
