Managing mixed fisheries for bio-economic viability

摘要: Management of fisheries for sustainability requires dealing with multiple and often conflicting objectives. A stochastic viability approach is proposed to address the trade-offs associated balancing ecological, economic social objectives in regulating mixed fisheries, taking into account complexity uncertainty dynamic interactions which characterize such fisheries. We focus on demersal fishery Bay Biscay more specifically fleets harvesting Norway Lobster (Nephrops norvegicus), Hake (Merluccius merluccius) Sole (Solea solea). bio-economic multi-species multi-fleet model technical developed examine between preserving Spawning Stock Biomass (SSB) every species maintaining profitability various fishing fleets. Different management strategies are tested compared. Results suggest that ensuring this a significant decrease capacity as compared reference year. The simulations allow comparing different allocations across
