Descripción
Waarnemingen.be - Fish occurrences in Flanders and the Brussels Capital Region, Belgium is a species occurrence dataset published by Natuurpunt. The dataset contains over 16,000 fish (Actinopterygii, Cephalaspidomorphi, Chondrichthyes, Leptocardii) occurrences of 132 naturally occurring species (native, vagrant or migrant species), recorded by volunteers (citizen scientists), mainly since 2008. The occurrences are derived from the database http://www.waarnemingen.be, hosted at the nature conservation NGO Natuurpunt in collaboration with Stichting Natuurinformatie. Standardized information regarding the occurrence's sex, lifeStage, behavior, occurrenceRemarks, and samplingProtocol is included as well.
Generalized and/or withheld information: location information is generalized to 5 x 5 km² Universal Transverse Mercator (UTM) grid cells. Observer name, exact XY-coordinates, toponyms, and photographs are not included in the published dataset, but are known in the source database.

Cobertura geográfica
Flanders and the Brussels Capital Region. These regions are situated in the north of Belgium and cover an area of 13,522 km² and 162 km² respectively (13,684 km² in total or 45% of the Belgian territory). Flanders is largely covered by agricultural land and urban areas while the Brussels Capital Region is mainly urban. All occurrence data are generalized to grid cells of 5 x 5 km² of the Universal Transverse Mercator (UTM) coordinate system, with the grid codes indicated in the field verbatimCoordinates. The WGS84 centroids of these grid cells are calculated in decimalLatitude/Longitude with a coordinateUncertaintyInMeters of 3,536 meters using Wieczorek et al. (2004).

Cobertura taxonómica
The dataset contains 132 naturally occurring fish (Actinopterygii, Cephalaspidomorphi, Elasmobranchii, Leptocardii) species (as well as a number of subspecies, formas and multispecies) recorded in Flanders and the Brussels Capital Region. This includes species that are native, vagrant or migrant. The class Actinopterygii is best represented in this dataset (113 species), in addition to 15 Elasmobranchii (Amblyraja hyperborea, Cetorhinus maximus, Dasyatis pastinaca, Lamna nasus, Leucoraja naevus, Mustelus asterias, Mustelus mustelus, Raja brachyura, Raja clavata, Raja microocellata, Raja montagui, Raja radiata, Raja undulata, Scyliorhinus canicula, Scyliorhinus stellaris), three Cephalaspidomorphi (Lampetra fluviatilis, Lampetra planeri, Petromyzon marinus) and one Leptocardii (Branchiostoma lanceolatum).

Métodos de muestreo
The observations (species, date, location, observer) were recorded by volunteers (citizen scientists) at http://www.waarnemingen.be. These consist of a mixture of casual observations of living and dead fish, and catches by different methods.
| Área de Estudio | See geographic coverage. |
|---|---|
| Control de Calidad | Recorded data are constantly verified by fish experts taking the observer’s species knowledge, added photographs and known species list of locations into account. The validation procedure from waarnemingen.be consists of an interactive procedure in which observers can be asked for additional information by a team of validators, after which the validator manually adds a validation status. Records that are not manually validated are additionally checked by an automated validation procedure that takes into account the number of manually validated observations within a specified date and distance range. 16% of the observations in this dataset are supported by a photograph on waarnemingen.be. The validation status is indicated in the field identificationVerificationStatus, the link to the original record in references. |
