Fish data collected during fishing contests in Flanders collected by the "Vlaamse Vereniging van Hengelsport Verbonden V.V.H.V. vzw" (Translated: Flemish Organization of Angling Associations). Data include catch frequency at species level, length frequency by fish groups and details about the total catches on the contests (total hours and effort spent, weight of total catch,...). More information on this dataset can be found in the Freshwater Metadatabase - BFE_14 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BFE_14).
