This wiki is under development, there might be omissions and errors. The data in many of the tables is only for demonstration purposes, not based on reality (yet).

This is the full list of potential inputs to the classification tables used for the various mitigation measures

Full list of classification table answers
Classification Selection (multiple)
Fish species for the measure Single or groups of fish species in Europe
Does the measure require loss of power production Operational (requires flow release outside turbine)
