Data of fish abundances and environmental conditions near the sluice-weir complexes in Balgerhoeke and Schipdonk in the Afleidingskanaal van de Leie (Belgium) in 2024 to assess the potential for upstream fish migration

The lock weirs in Balgerhoeke and Schipdonk (Afleidingskanaal van de Leie, Belgium) form a barrier for eel, cyprinids, and other fish species. Research was conducted to determine the extent to which these barriers affect existing populations, whether fish can pass through, and whether passage facilities could be effective. Fykes were used to capture fish and was followed by species identification, length and weight determination and counting. Environmental data was obtained via waterinfo.be.
