Silver eel escapement in the River Ems

• Central objective of European eel management is the increase ofsilver eel escapement. • In Germany, a specially developed population model is used to estimate the number of silver eels that leave German river basin districts. • In order to validate this model, an exemplary investigation was made in the Ems river to determine whether the modeled escapementfigures correspond to reality. • The results show that the actual number of escaping silver eels from the Ems is significantly lower than predicted by the model.
