The River Scheldt basin is highly fragmented and regulated with various water regulating structures such as shipping lock complexes, weirs and even a few hydropower turbines. These structures pose important migration barriers for diadromous and potamodromous fish species as they need to migrate between various habitats to complete their life cycle. Through this tracking study, the movement and migration behaviour of a number of diadromous and potamodromous fish species will be studied in relation to these migration barriers, but also the effectivity of fish passes when present. Hence, this study enables the investigation of the movement and migration behaviour of both diadromous and potamodromous fish species on a river basin scale in relation to various anthropogenic impacts, as well as mitigation measures.
