Abstract or Summary
  • In the past two decades, the French Guyana shrimp fishery has known dramatic evolutions, largely driven by global changes. On the economic side, two major driving factors are the globalization of the shrimp market, with a decreasing trend in real prices, and the long-term increase in fuel prices worldwide. On the environmental side, recruitment of the two main species of shrimp targeted in the fishery seems to have decreased over the last decade, probably due to hydroclimatic modifications. It is important to assess the adaptive capacity of the fishery facing such changes, as well as the impact of past and future public policies on this capacity. A bio-economic model of the French Guyana shrimp fishery was developed in order to analyze the dynamics of the fishery. The aims of the modeling exercise were: 1) to account for the changes observed in the fishery over the past ten years and major drivers of those changes; 2) to simulate possible responses of the fishery to economic changes but also to environmental perturbations or regime shifts; and 3) to assess the consequences of past and possible future public policies on the bioeconomic viability of the fishery. The paper presents the key results derived from this modeling exercise, as regards assessment of the adaptive capacity of the fishery to global changes, and the role of public policies in this respect. This research was carried out as part of the Chaloupe program (http://www.projet-chaloupe.fr) funded by the French National Agency For Research (ANR).
