Large-scale movement patterns of European catfish (Silurus glanis L.) in the Scheldt River basin, Belgium.

The large-scale movement behavior of European catfish (Silurus glanis L.) remains poorly understood, despite it being a species of interest for conservation management. We report the movement patterns of 13 native individual catfish, recorded using acoustic telemetry over 160-km estuarine habitat free of migration barriers in the Scheldt River basin (Belgium).
