| Resumen: | The small-scale fisheries sector in many Pacific islands is facing increasing challenges in relation to resource availability, economic opportunity, and demographic and social pressure. In particular, intensifying cash-oriented livelihood strategies can exacerbate existing vulnerabilities and threaten food security and resource conservation. In this paper the authors develop a bio-economic model and a quantitative measure of resilience in order to explore the interaction between socio-economic and ecological dynamics, and to analyze the potential role that cooperation and collective arrangements can play in this interaction to maintain the viability of the system. Based on the case of the system known as wantok typically found in the Solomon Islands, numerical examples are used to explore the potential gain that cooperation between fishers can bring in terms of subsistence, profitability and ecological performances, as well as the resilience of the whole system to shocks. |

| Resumen: | This paper offers a theoretical and empirical model of ecosystem-based fishery management. A multi-species and multi-fleet model integrating Lotka-Volterra trophic dynamics as well as production and profit assessments is developed and applied to the coastal fishery of French Guiana. This small-scale fishery constitutes a challenging example with high fish biodiversity, several non-selective fleets and a potentially increasing local food demand due to demographic growth. The dynamic model is calibrated with 13 species and four fleets using monthly catch and effort data from 2006 to 2009. Several contrasted fishing scenarios including status quo, total closure, economic and viable strategies are then simulated. They are compared from the viewpoints of both biodiversity preservation and socioeconomic performance, assuming fixed landing prices and fixed costs. We show that fishing outputs, including food supply and fleet profitability, can be sustained on average but a loss of species cannot be avoided. |
