This paper presents an application of stochastic viability approach in a tropical small scale fishery context, offering a theoretical and empirical model of ecosystem-based fishery management. A multi-species and multi-fleet bio-economic model integrating Lotka-Volterra trophic dynamics as well as production and profit assessments is applied to the French Guiana coastal fishery. This case study is interesting as consistent time series data are available with data collection system set up since 2006. The dynamic model is calibrated with thirteen species and four fleets using monthly catch and effort data from 2006 to 2010. We compare different management strategies relying on different combinations of fishing effort, from the viewpoints of both biodiversity preservation and socio-economic performance, assuming fixed landing prices and fixed costs. The risk for the fishery to mismatch the potential local fish demand growth is pointed out, as well as the loss of species which cannot be avoided without closure.
