INSPIRE - Annex I Theme Hydrography - Physical Waters - Waterbody - Watercourse - Fish as a Biological Parameter for Ecological Status 2015

Par Administration de la gestion de l'eau

According to the water framework directive (Directive 2000/60/CE), the biological parameter fish are monitored in surface water bodies in order to determine the ecological status. Fish react sensitively to the continuity and the hydrological flow of surface water. Fish are therefore sampled in the…
