The Division of Fishes serves a region in North America noted for a wide range of ecotypes and elevational gradients, from the Rocky Mountains to the Great Basin and the Great Plains, with the convergence of three major deserts, the Chihuahua, Sonora, and Mojave. The fish fauna of New Mexico (and the southwestern US) is characterized by high endemism, diversity, and remarkable physiological tolerances.The MSB collection of fishes provides a 70-year window on the natural history of New Mexico's imperiled native fishes and aquatic systems. The MSB has over 96,000 cataloged lots of fishes (4,153,582 specimens), representing 63 families, 178 genera, and 420 species, collected between 1938 and present day. MSB fish records, available on also available on FishNet2, include all holdings except for fishes collected on private and Tribal lands. The MSB Division of Fishes does not hold holotypes and divides collections of paratypes with other permanent fish collections. Over 60,000 pages of field books and field data forms are archived in the Division.
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 12,313 records.
5 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.

The MSB Division of Fishes collections are from the southwestern US, primarily the Chihuahua Desert of New Mexico, with good representation from the Rio Grande,and the Gila, Pecos, Canadian, San Juan, and Zuni Rivers.
|Bounding Coordinates||South West [-90, -180], North East [90, 180]|
The MSB Division of Fishes collections are predominately cypriniform fishes, collections of native and endemic minnows and suckers from the Rio Grande, Gila and Pecos Rivers; other well-represented groups fishes are the Cyprinodontidae, Ictaluridae, and Centrarchidae.
|Living Time Period||1900 to present|
