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 2013_albertkanaal, using VEMCO tags (V7, V9, V13) and receivers (VR2AR, VR2Tx, VR2W). In total 161 female individuals of European eel (<i>Anguilla anguilla</i>) and 134 (hatched) smolts of Atlantic salmon (<i>Salmo salar</i>) were captured, tagged and released between 2013 and 2017, to study the effect of shipping locks and hydropower plants on their downstream migration in the Albert canal.
