During 23 years, 3 institutions sampled fish in the Belgian part of the River Meuse with two distincts methodologies.
Data were provided by the survey of fish passages in fish ladders at Tailfer (upstream Namur) and Lixhe (downstream Liège) over the 1989-2012 period (Matondo & Ovidio 2016). Fish were collected daily in a trap placed in the upper pool of the ladder when the migration peaks occurred, and twice a week outside the major migration period. All the fish species were identified and species abundances were estimated without taking into account the juveniles and the youngs-of-the-year. Annual fish abundances were expressed as monthly averages.
Data from Hastière, Andenne and Visé were provided by electrofishing from a boat along the banks in 1994, 2007, 2008, 2009 and 2010. Abundances were expressed as number of individuals per 100m² of river sampled.
Environmental and invertebrate data of the River Meuse are also available as separate datasets.

sample specifications:
specification of method(s) used for sampling and sorting:
During 23 years, 3 institutions sampled fish in the Belgian part of the River Meuse with two distincts methodologies:
- 2 multispecies fish ladders were monitored at Tailfer and Lixhe. Fish were collected in a trap placed in the upper pool of the ladder, every day when the migration peaks occurred, and twice a week outside the major migration period. All species were quantified and identified at the specie level, except for the young of the year of all species. Fish abundance was expressed as monthly average.
- 2000 meters of river were sampled at 3 sites, Hastière, Andenne and Visé, by electrofishing from a boat along the banks in 1994, 2007, 2008, 2009 and 2010. All species were quantified, measured and identified to specie level. Abundances were expressed as number of individuals per 100m² of river sampled.
