Sampling

Fish were caught using various methods; each of them defined according the habitat. In freshwater systems were used electrofishing, cast net throws (0,5-3 cm mesh size), gill nets (1-12 cm, mesh size), bottom trawls (0,5-3 cm, mesh size) and hooks lines (different sizes). In marine systems, we used mainly hook lines and gill nets. Although there was not a general sampling design, most of the samples in freshwater systems were taken in different climatic moments (rains and dry periods)

Quality Control

Species of each specimen was determined using specialized literature. All the scientific names of specimens were validated by the updated fish checklist in Catalog of Fishes-California Academy of Sciences (Eschemeyer and Fong, 2016). Most of the specimens are preserved in alcohol 96% and other ones are dry preservation (skeletons). A lot consists of all specimens of a species collected at the same climatic period and place. Each lot contains a paper tag with the main information about date and sampling site such as the Systematic information of the species; all of them are located inside metal cabinets protected from light. Because of the little space to store, lots are organized by a serial number. Data of each specimen (Species, Genera, Family, Order and Class), and date of sampling and collector name were recorded in a excel data set following recommendations of Darwin Core format and in the CIUA Museum Book. Some geographical information is also part of the data set associated to each lot. Some of those are: geographical records, locality name, and altitude. The latitude and longitude of sampling sites were plotted and cleaned using the menu facility of ModestR (García-Roselló et al., 2013) and Georreference protocol of Alexander von Humboldt Institute (Escobar D et al 2014) whit sofware Qgis.

Method steps

1. 1. Sampling desing. 2. field sampling and environmental description about fish habitat. 3. fish fixation in formaldehide 10% 4. Fish species determination. 5. Specimen data record in the data bases (book, DWCore and label). 6. Storage in the fish collection.

CIUA fish dataset 340 species, most of the specimens were identified to specie level (90.1%). Perciforms and Characiforms Orders were the more represented into the database.

The CIUA Fish Museum is a regional museum covering mostly Colombian Andean region. Department of Antioquia is the most significant political division with 283 sampling localities, 2492 records and 12909 specimens. Most of the records in CIUA database come from marine and freshwater aquatic systems in the northwestern Colombia (Fig.1). Dataset is from the coastal line of the Pacific Ocean and the Caribbean Sea, and seven river basins Magdalena-Cauca, Meta, San Juan de Urabá, Sinú and Atrato. Most of the records come from freshwater systems (96%); mainly from creeks (33%) and rivers (41.8 %) (Fig. 2).Altitudinally, specimens in CIUA were collected between 0 and 3486m.a.s.
