Assessing the Impact of Royalties on Fishery Resource

For the conservation of the fish population, a mix of legal, technical, social and economic instruments must be used, among which we find royalties. Beyond the fact that it is a source of budgetary revenue, depending on its amount, the royalty is meant to help avoid overexploitation of fishery resources, but within a mechanism that combines economic, social and environmental criteria. The modelling of this mechanism, as well as the evaluation of the ecological impact that it generates, represent the objectives of the approaches for conducting scientific research on this topic. To purely biological (based on maximum sustainable yield) and bio-economic models (which also take into account the fishing effort), we add an ecological model, which highlights, in the same plan, the economic, social and ecological optimum.
