Escapement Success And Patterns Of Downstream Migration Of Female Silver Eel Anguilla Anguilla In The River Meuse
Downstream migration of female silver eel Anguilla anguilla (L.) was studied by remote telemetry in the lower part of the River Meuse (Belgium and The Netherlands) using a combination of 9 detection stations and manual tracking. N=31 eels (LT 64-90cm) were implanted with active transponders and rele...
