A model for the upstream motion of elvers in the Adour River.
The aim of this paper is contributing to the study of the exploitation of the European eel (Anguilla anguilla) in the basin of the French river 'Adour'. This exploitation constitutes the basis of the economy of local professional fishermen, who have recently noticed a diminution of the hunting of elvers. In order to design a sustainable exploitation strategy, we must know as much as possible about eel life cycle. For that purpose, we build a model to describe a phase of eels evolution, their migration upstream the river. Our model is based on the biological details of eels behaviour and constitutes a virtual laboratory, useful to test different hypotheses about eels migration.
