An original eco-anthropological approach to identify a diadromous species that could materialise the recovery of the water and habitat quality within the Seine basin

In a context of improvement of water and habitat quality, the Seine basin authority calls for a proposal to "select a diadromous fish among the 11 historically present species which could be used to illustrate the recovery". We have proposed an approach without any a priori choice of species with both ecological and anthropological approaches.
