The database reflects the widely distributed data for Italian freshwater fish occurrences collected in the last 20 years. These data are actually hidden in fisheries plans and studies of the Italian provinces, regions, parks, and some other local administration databases and “grey literature”. These databases and literature resources are collected together, and the records are georeferenced and organized into one database (using Artedian http://artedi.nrm.se/fishbase_se/software/artedian/). More information on this dataset can be found in the Freshwater Metadatabase - BF_CF22 (http://www.freshwatermetadata.eu/metadb/bf_mdb_view.php?entryID=BF_CF22).
