Full Title

Fishes in MZNA-VERT: freshwater communities in the Larraun river (Spain). PhD project, Javier Oscoz & Master project, A. Cos.

Description

Purpose

The aim of the present data set is to provide all information of the records of freshwater fishes gathered in the research project carried by Dr. Oscoz about the biology and ecology of several species of freshwater fishes in the Larraun river, Navarra, Spain.

Additional Information

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). MZNA attends to reserchers around the world, make loans and accepts deposits.

Study extent

The specimens were captured in eleven sampling points of eight towns (Aitzarreta, Urritza, Iribas, Irurzun, La Ferreria, Latasa, Lecumberri and Muguiro) of the Larraun River in the years 1996, 1997, 1998, 2005 and 2010.

Sampling description

The main sampling method was electric fishing. The method used was three-run depletion between two stop-nets. The captured individuals were sedated with 2-phenoxyethanol, identified, counted and measured (total length in mm). Then, fishes were returned to the river. Some specimens were euthanized, studied in the laboratory and deposited on the Museum of Zoology of the University of Navarra (MZNA, Pamplona, Spain). Species identification was performed by J. Oscoz and R. Miranda.

Quality control

Species identification was performed by R. Miranda and J. Oscoz 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 Steps

1. Specimens were sampled following the procedure described in the Sampling description section. The individuales were identified, measured and released in the majority of cases. Some specimens were euthanized and deposited on the Museum of Zoology of the University of Navarra in labelled jars first with formalin and, more recently, with 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.
