Diadromous species use both Marine and continental environments. They are subjected to multiple stressor acting locally or at the global scale. Currently ICES has designed its databases for the marine environment, and we need an habitat referential to better account for stressor (dam, connectivity, pollution, fishery) acting at the very local scale in the continental environment. The objective is to propose a vocabulary for habitat based on the hydroshed database and covering all continental freshwater and transitional habitats across Europe, but also to provide a referential for units from the river, to the wider stock level, including the marine environment, and adapted to the needs of the diadromous expert groups (WGNAS, WGBAST, WGTRUTTA, WGEEL).
