Summary

Full Title

VIS - Reference freshwater monitoring in Flanders, Belgium (post 2013)

Description

VIS - 'Reference Freshwater Monitoring’ in Flanders, Belgium is a sample based dataset published by the Research Institute for Nature and Forest (INBO). The database is described in Brosens et al. 2015 (http://doi.org/10.3897/zookeys.475.8556). The dataset contains over 25,000 fish occurrences sampled between 2013 and 2015 from 246 in inland rivers, streams and canals in Flanders, Belgium. The dataset includes 42 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/inbo/data-publication/blob/master/datasets/vis-freshwater-monitoring-events/README.md

Purpose

The Fish Information System or VIS (http://vis.milieuinfo.be) is a database created by the Research Institute for Nature and Forest (INBO) which is used to monitor the status of fishes and their habitats in Flanders, Belgium and to calculate the biotic integrity (Karr 1981, Belpaire et al. 2000, Breine et al. 2004, 2007, 2010) of fish assemblages. It contains data regarding occurrences, individual morphometrics, stocks, pollutants, indices, and non-native fish species. Sampling has been going on since 1992, the database model was designed in 1994 (Verbiest et al. 1994), the first database developed in 1996 (Verbiest et al. 1996), and the consolidated database set up in 2001. VIS is used for supporting NATURA 2000, an ecological network of protected areas in Europe and to calculate the EQR (Ecological Quality Ratio) in the framework of the EU Water Directive (Directive 2000/60/EC). Further, the database provides updated information for Flemish Red Lists of fishes and lampreys (Verreycken et al. 2014) and on the distribution status of non-native and invasive fish species. The data are also crucial in fish stock management and for reporting on the status of the European eel stock as required by the Eel Regulation (Council Regulation (EC) N° 1100/2007). This dataset is a standardized extraction of all inland water species occurrences from VIS.

Taxonomic Coverage

The dataset contains 64 fish species reported from Flemish watercourses, as well as a number of non-target species (mainly crustaceans). This dataset also includes a number of typical brackish water fish species which sometimes can be found in inland water sites in proximity to the sea and/or behind the sluice gates. The class of Actinopterygii is best represented (63 species), along with one Petromyzontida (Lampetra planeri) and 7 crustaceans from the order Decapoda.

Methodology

Study extent

Over 2,000 locations in estuaries, inland rivers, streams, canals, and enclosed waters in Flanders, Belgium have been sampled, from March to November, since 1992. In 2001, these locations were consolidated in a monitoring network (“VISmeetnet -”) of 900 sampling points. The geographic coordinates in the dataset are those of the defined sampling locations (dwc:locationID). However, as these coordinates are not always exact the actual coordinates of the catch, which may be located further up- or downriver, the coordinate uncertainty (dwc:coordinateUncertaintyInMeters) has been set to 250 meter. Information on the data collected before 2013 can be found in Brosens et al, 2015. From 2013 data was collected, only by using a subset of the Fish Reference Network, the Flemish Reference Freshwater Monitoring. This subset holds about 300 measuring points. The methodology before and after 2013 is equal, except that in the post 2013 survey period multiple fishing events were performed on the same location (Depletion fishing).

Sampling description

Standardized sampling methods were used as described in Belpaire et al. (2000) and Van Thuyne & Breine (2010) and are specified in the dataset as dwc:samplingProtocol. Per water body, the same method was used for each sampling event. The default method is electric fishing, but additional techniques such as gill nets, fykes, and seine netting (variable sizes) were used as well. Electric fishing was carried out using a 5 kW generator with an adjustable output voltage of 300–500 V and a pulse frequency of 480 Hz. The number of electric fishing devices and hand-held anodes used depends on the river width (Belpaire et al. 2000). In riverine environments, electric fishing was carried out on both riverbanks in upstream direction. All fishes were identified to species level, counted, and their length and weight was measured (measurement data available upon request). Since 2013, electric fishing was carried out until depletion.

Quality control

Strict field protocols where used. The Manual for Application of the European Fish Index (EFI) (Fame consortium 2004) served as a guideline for electrofishing and was used in support of the EU water framework directive.

Method Steps

  1. Water type: Running freshwaters (width: 1.5 m, depth: < 1.30 m) Method: electrofishing with 1 anode by wading Effort: 100 m
  2. Water type: Running freshwaters (width: 6 m, depth: < 1.30 m) Method: electrofishing with 2 anodes by wading Effort: 100 m
  3. Water type: Running freshwaters (width: > 6 m, depth: < 1.30 m) Method: electrofishing with 2 anodes by wading Effort: 250 m with 1 anode on each riverbank, 2 m from bank
  4. Water type: Running freshwaters, streaming rivers (width: > 6m, depth: > 1.30 m) Method: electrofishing with 2 anodes by boat Effort: 250 m with 2 anodes on each riverbank, 2 m from bank
  5. Water type: Canals, slowly running rivers (width: > 6 m, depth: > 1.30 m) Method: electrofishing with 2 anodes by boat AND 2 fykes Effort: 250 m with 2 anodes on each riverbank, 2 m from bank AND 1 fyke for 48 hours parallel with and on both riverbanks
  6. Water type: Canalized rivers with too high conductivity for electrofishing (depth: < 1.30 m) Method: seine netting Effort: 100 m, two times complete seine netting
