Assessment of the entering stock, migration dynamics and fish pass fidelity of european eel in the belgian meuse river
peer reviewed Migration dynamics of incoming eels in Belgium via Lixhe in the Meuse River were investigated using two fish passes with different configurations— net traps and automatic detection stations—as tools to distinguish resident and migrating eels. From April to September 2013, 435 eels (P50...

From April to September 2013, 435 eels (P50 length, 403 mm; range, 196–836 mm) were caught (daily maxima catch, 90 eels per day), 90% between 13 June and 1 August (50 days) and P50 on 19 July. Eels migrated mostly at 19–26 °C (P50, 24.4 °C), river discharge 65–314m3 s 1 (P50, 84m3 s 1), during the dark at 00:00–05:00 h and during both the waxing and waning phases of moonlight.

peer reviewed Migration dynamics of incoming eels in Belgium via Lixhe in the Meuse River were investigated using two fish passes with different configurations— net traps and automatic detection stations—as tools to distinguish resident and migrating eels.
