Checklist of non-native freshwater fishes in Flanders, Belgium

The Checklist of non-native freshwater fishes in Flanders, Belgium is a species checklist dataset published by the Research Institute for Nature and Forest (INBO). It container information on 23 alien fish species occurring in Flemish natural and semi-natural water bodies, detected in sampling between 1992 and 2006. This species checklist was assessed within the framework of the Freshwater Fish Monitoring Network by VERREYCKEN et al. (2007) and reassessed for VERREYCKEN et al. (2018). Here it is published as a recognised Darwin Core Archive and including for each species: the scientific name, Kingdom, and stable taxon identifier (in the taxon core), the Dutch and English vernacular name (in the distribution extension), the year of first introduction in Flanders (given as a year range, with the year of last observation stamp), the pathway (s) of introduction and the degree of establishment in Flanders (in the distribution extension), Coarse habitat information (in the species profile extension) and native range (s) (in the description extension). The dataset can be used for researching and managing aquatic Invasions or compiling regional and national registers of alien species.
