This is an acoustic telemetry dataset published by the Research Institute for Nature and Forest (INBO). It contains animal (fish) tracking data collected by the Permanent Belgian Acoustic Receiver Network (<a href=\"https://lifewatch.be/en/fish-acoustic-receiver-network\">https://lifewatch.be/en/fish-acoustic-receiver-network</a>;) for the project/study 2012_leopoldkanaal, using VEMCO tags (V7, V13) and receivers (VR2AR, VR2W). In total 104 female individuals of European eel (<i>Anguilla anguilla</i>) were captured, tagged and released in 2011 and 2012, to study their movement behaviour during the yellow eel stage and migration behaviour during the silver eel stage for 4 years in Meetjesland, a polder area in Flanders, Belgium.
