Registros de Dados
Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 262 registros.
Também existem 1 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Métodos de Amostragem
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.
| Área de Estudo | 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. |
|---|---|
| Controle de Qualidade | 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. |
