Acquisition de données de captures par pêche en vue de la gestion de populations de poissons, contraintes et méthodes en fonction des objectifs : exemple de l'anguille

Abstract : The manager often needs to have information on fishermen's activity and their captures on variable scales, depending on the ecology of the species, with regard to fish species that exhibit some fishing interest. In France, an important delay exists in terms of collecting social-economic data on these activities in continental waters. However, after experimentation, it was found that access to this type of information was possible, should adapted techniques and methods be developed. It seems also that, if some precautions are taken, these data can be collected from fishermen and they can be used to demonstrate and understand particular biological phenomena. To illustrate this, the eel, Anguilla anguilla L., a amphihaline migratory fish, that has a particularly complex cycle and that is used at any of its life stages in continental waters, has been selected. Two very different examples are voluntarily developed. The first consits in evaluating eel production by fluvial professional fishermen at the national level, using certain survey and result interpretation techniques. The second consist in characterizing and quantifying glass-eel migration, using the "Captures par l'Unité d'Effort" (CPUE) obtained through monitoring of a professional fishery in a fluvio-estuarine system.
