Stochastic Multi-species MSY to Achieve Ecological-Economic Sustainability of a Coral Reef Fishery System in French Polynesia

This paper investigates the ecological-economic sustainability of coral reef socio-ecological systems under fishing and environmental pressures. To achieve this, a dynamic, spatially explicit, multi-species, multi-fleet fisheries model is developed. Stochastic shocks are assumed to alter cover consequently entire social-ecological system. The calibrated using ecological, socio-economic data in French Polynesia. Four exploratory strategies goal-seeking strategy entitled Multi-Species Maximum Sustainable Yield (SMMSY) compared terms outcomes SMMSY turns out promote sustainability. It characterised by global increase effort pointing relative current under-exploitation fishery. balances trophic level catches after natural sustains fundamental herbivore grazing process. also more diversified temporality, gears, spatial distribution target species.
