取樣方法
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.
| 研究範圍 | In 2011, we made a sample for the monitoring of bitterling, small mud creeper, pond sculpin and brook lamprey within the framework of the Habitats Directive. For each species, we used a sampling frame consisting of all watercourses (divided into the strata Flemish watercourses, 1st order watercourses and 2nd order watercourses) where the species was caught in the past. We first checked how many monitoring points could be expected for each species and within each stratum in the reference monitoring network for the Water Framework Directive. We then selected additional monitoring points from the sampling frame via random sampling so that we obtain at least 45 monitoring points per species and so that there is a representative distribution of monitoring points across the different strata. We call these additional measurement points the compaction measurement network. |

| 品質控管 | 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. |
方法步驟描述:
- Data was collected and imported in the VIS database by the INBO fishing team
- A specific SQL query was created to map the data to darwin core
- data is published through the INBO IPT to GBIF
