Fishes in MZNA-VERT: populations affected by the Itoiz dam in the Irati river (Spain).Acronym: ICHTY-MPPI
One of the main threats to freshwater fish species is habitat fragmentation caused by dams. Publishing collected data of location and abundance of species is useful tool to determine the ecology and health of the populations and perform efficient management and conservation plans. Here, the effects of the new Itoiz dam (Navarra, Spain) in fish populations are analyzed in a six year long study.
The specimens recorded in this dataset are collected in the Irati river, a tributary of the river Ebro (Spain), downstream of the Itoiz dam.
The aim of the present data set is to provide all information of the records of freshwater fishes gathered in a project about the effect of the Itoiz dam, Navarra, Spain.
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.
Specimens were sampled following the procedure described in the Sampling description section. The individuals 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.
