Description
The river blenny (Salaria fluviatilis) is catalogued as endangered in Spain so the monitoring of the distribution and health of its populations is a good tool for its conservation. This dataset contains records of Salaria fluviatilis and other fish species captured in the Segre and Susia rivers (north of Spain) during two monitoring programs.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3,018 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
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.

Geographic Coverage
All specimens were collected in the Segre river in Ponts and downstream of the Rialb dam (Gualter, Spain) and the Susia river upstream the El Grado dam. Both rivers, Segre and Susia, are tributaries of the Ebro river and finally flow into the Mediterranean sea.

Taxonomic Coverage
All specimens were identified to the species level using the Guide to Freshwater Fish of Britain and Europe (Maitland P. S. & Linsell K., 1977). Sixteen species were recorded, nine of the Cyprinidae family. The rest of the collected species belong to the families Salmonidae, Nemacheilidae, Cobitidae, Percidae, Centrarchidae, Bleniidae and Anguillidae. The 59% of the captures belong to the Cyprinidae family. Moreover, five species recorded in this dataset are endemic from the Iberian Peninsula and five are introduced.

Project Data
Salaria fluviatilis is the only freshwater member of the family Bleniidae, threatened with extinction in the Iberian Peninsula. Information of this dataset is gathered from four research projects: two projects specifically funded the study of this species and other two projects that indirectly provided the opportunity of recovering information about the biology and habitat preferences of this species.

Sampling Methods
The main sampling method was electric fishing, using a back-pack electrofishing unit. The captured individuals were sedated with 2-phenoxyethanol, identified, counted and measured (total length in mm). Then, fishes were returned to the river. Invasive species were euthanized, studied on the laboratory and deposited on the Zoological Museum of the University of Navarra (MZNA, Pamplona, Spain).
| Study Extent | The specimens were captured in two localities of the Segre river (Gualter and Ponts) and two in the Susia river (near Grado dam and Javierre) in the years, 2003, 2005 and 2006. |
|---|---|
| Quality Control | Species identification was performed by R. Miranda using suitable literature (Maitland & Linsell 1977) and scientific names were validated using the W. N. Eschmeyer’s Catalog of Fishes (Eschmeyer 2014). Specimens were returned to the river or deposited in the Museum of Zoology of the University of Navarra. Each specimen was labelled with a unique collection number. Darwin test software (v3.3 Ortega-Maqueda and Pando 2008) was used to check out possible mistakes in the coordinates, characters and the format of dates. |
Method step description:
- Specimens were sampled following the procedure described in the Sampling description section. The individuals were identified, measured and released in the majority of cases. In some cases the specimens were euthanized and deposited on the Museum of Zoology of the University of Navarra in labelled jars, preserved with formalin and later in 70% ethyl alcohol. Field data was revised, digitalised and incorporated to the MZNA database (Zootron v4.5, Ariño 1991). The dataset was exported to DarwinCore v1.4 format and revised to correct errors to adequate it to DarwinCore standars. Metadata information was added and the Darwin Core Archive was incorporated to the Spanish GBIF IPT.

Additional Metadata
The Museum of Zoology (MZNA) was founded in 1980 as a repository of zoological materials originating from research and instructional activities of the department of Environmental Biology (proviously known as the department of Zoology and Ecology) of the University of Navarra. Nowadays MZNA store more than two millions specimens in its climate-controlled facilities. The Museum is a Data Provider for the Global Biodiversity Information Facility (GBIF) and is an Affiliate to the International Commission of Zoological Nomenclature (ICZN). The Museum is also in charge of the curation and management of the Natural History Collections of the School of Science of the University of Navarra (Spain). The MZNA attends to reserchers around the world, make loans and accepts deposits.
| Purpose | The aim of the present data set is to provide all information of the records of Salaria fluviatilis and other fish species captured in the Segre and Susia rivers (north of Spain) during two monitoring programs. |

| Maintenance Description | Dataset is closed. The regular maintenance of the preserved material could imply modification of some metadata related with curatorial units. New versions of the dataset will be published when required. |
