Abstract
Waarnemingen.be - Fish occurrences in Flanders and the Brussels Capital Region, Belgium is
a species occurrence dataset published by Natuurpunt. The dataset contains close to 13,000
fish occurrences of 125 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.
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.

Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). We
would appreciate however, if you read and follow these norms for data use
(http://www.natuurpunt.be/normen-voor-datagebruik [in Dutch]) and provide a link to the

to LifeWatch.

General description
Purpose: Because of their submerged life-cycle, fish observations are classically
under-represented in datasets of casual observations. This is also the case in
waarnemingen.be. But by making it easy to record any fish species, both marine and
freshwater, while making other observations, the website http://www.waarnemingen.be has
made it possible to report fish observations more easily and hence stimulated the number of
documented casual observations but also catches. However, most amateur fishermen catches
and probably all of the commercial fish catches remain unrecorded.

Taxonomic coverage
General taxonomic coverage description: The datasets contains 125 naturally occurring
fish species (as well as a number of varieties, hybrids and multispecies) recorded in Flanders
and the Brussels Capital Region. This includes species that are native, vagrant or migrant. If
the observer remarked that the specific individual was introduced by man, then this is
recorded in the field establishmentMeans. The class Actinopterygii is best represented in this
dataset (108 species), in addition to 13 Chondrichthyes (Cetorhinus maximus, Dasyatis
pastinaca, Leucoraja naevus, Mustelus asterias, Mustelus mustelus, Prionace glauca, Raja
brachyura, Raja clavata, Raja montagui, Raja radiata, Raja undulata, Scyliorhinus canicula,
Scyliorhinus stellaris), three Petromyzontida (Lampetra fluviatilis, Lampetra planeri,
Petromyzon marinus) and one Leptocardii (Branchiostoma lanceolatum).

Spatial coverage
General spatial coverage: 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.
Coordinates: 50°40'48''N and 51°30'36''N Latitude; 2°31'48''E and 5°55'12''E Longitude

Methods
Method step description: Not provided.
Study extent description: See geographic coverage.
Sampling description: 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.
Quality control description: 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.
