Fishes in MZNA-VERT: freshwater communities in the Larraun river (Spain). PhD project, Javier Oscoz & Master project, A. Cos.Acronym: ICHTY-TPRL
Rivers suffer from a wide range of human impacts that need to be studied (Oscoz, 2003). The ecologic quality of the Larraun river was analysed between 1996 and 1998 to assess the impact caused by the building of a new road and industrial activities: water quality, habitat, macroinvertebrates and fish community. The river presented organic pollution near towns and high nitrite levels. Data about fish biometry, age and feeding are given in the study. Some years later, the river was sampled to analyse the evolution of the fish populations after the building of the road.
The Larraun river is a 19 km long tributary of the Arakil river (Ebro basin, north of Spain).
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.
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.
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.
