<p>VIS - Fishes in inland waters in Flanders, Belgium is a species occurrence dataset published by the Research Institute for Nature and Forest (INBO) and described in Brosens et al. 2015 (https://doi.org/10.3897/zookeys.475.8556). The dataset contains over 350,000 fish occurrences sampled between 1992 and 2012 from over 2,000 locations in inland rivers, streams, canals, and enclosed waters in Flanders, Belgium. The dataset includes over 64 fish species, as well as a number of non-target species (mainly crustaceans). The data are retrieved from the Fish Information System (VIS), a database set up to monitor the status of fishes and their habitats in Flanders and are collected in support of the Water Framework Directive, the Habitat Directive, certain red lists, and biodiversity research. Additional information, such as measurements, absence information and abiotic data are available upon request. Issues with the dataset can be reported at https://github.com/LifeWatchINBO/data-publication/tree/master/datasets/vis-inland-occurrences</p><p>Length and weight measurement data of the individual fishes, absence information, occurrence data since 2013, as well as abiotic data of the sampling points (pH, temperature, etc.) are not included in the Darwin Core Archive and are available upon request.</p><p>To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/).
