Taxonomic Comments
This species was removed from the genus Agosia and placed in the genus Rhinichthys by Woodman (1992). Simons and Mayden (1999) recommended that the species be retained in the monotypic genus Agosia until its relationships are further clarified. Nelson et al. (2004) followed this recommendation.

Rank Reasons
Fairly large range in southern Arizona, southern New Mexico, Sonora, and Sinaloa; declines have occurred, and threats are apparently widespread and ongoing, but the species remains relatively widespread and abundant.
Range Extent Comments
Range includes the Lower Colorado River drainage (primarily Gila and Bill Williams river systems), New Mexico and Arizona, and south through southern Arizona and Pacific drainages of western Mexico to at least the Rio de la Concepcion, Mexico (Miller 2005, Minckley and Marsh 2009, Page and Burr 2011). This fish is Introduced and established in the Mimbres River, Rio Grande basin (below Elephant Butte Reservoir; localized) and Rio Hondo (local), New Mexico; it has been recorded but apparently is not established in the Virgin River, Zuni River, and a few other places (Sublette et al. 1990, Minckley and Marsh 2009).
Occurrences Comments
This species is represented by a large number of occurrences (Minckley and Marsh 2009). Records are from approximately seven drainages with 100+ occurrences. The Arizona Natural Heritage Program recorded 127 occurrences all of which are believed to be extant (Sabra Schwartz, pers. comm., 1998). The Texas Natural History Collection index of North American freshwater fishes (TNHC 1996) mapped a total of 84 records from approximately seven drainages with 29 records from Mexico, seven records from New Mexico, and 48 records from Arizona. Lee et al. (1980) mapped about 165 records from approximately seven drainages with 47 records from Mexico, 18 records from New Mexico, and 100 records from Arizona. The difference in the numbers of records on the two maps may simply represent a combining of records on the TNHC map; the overall distributions are similar.
Threat Impact Comments
Threats include habitat alterations and interactions with non-native fish species. Large areas of habitat have been destroyed by dewatering, stream diversion, groundwater pumping, dam construction, channel and watershed erosion, and other factors. Additional water development and ongoing watershed damage threaten large portions of the remaining range (U.S. Fish and Wildlife Service 1994). In the Aravaipa Creek Canyon area, populations are threatened by over appropriation of aquifer water and the invasion of non-native fishes. The red shiner is present in the Gila River and has been suggested as a potential competitor for native species (New Mexico Department of Game and Fish 1997). The listing priority form of the U. S. Fish and Wildlife Service (1994) considered the degree of threat to be moderate to low.
Ecology & Habitat
Habitat
This highly adaptable fish occurs in diverse situations ranging from low-elevation desert streams to cool, clear mountain streams, generally at elevations below 1,500 meters in the north but ranging to 2,000 meters in the south (Lee et al. 1980). Typically it occurs in shallow sandy and rocky runs and flowing pools of creeks and small to medium rivers, often near cover (Page and Burr 2011); also in eddys and pools near overhanging banks or other cover. During low water, individuals may take refuge in moist detritus and algal mats (Sublette et al. 1990). It is tolerant of high temperatures and low dissolved oxygen.
Spawning occurs in shallow depressions in fine sand along shoreline at depths of 5-20 cm; eggs are buried by the spawning act (Johnston and Page 1992). Young remain in the nest until the yolk sac is mostly absorbed before moving to stream edges.

Reproduction
Spawns reportedly year-round, or December-July with peak in April (Sublette et al. 1990). During summer young hatch in less than 4 days. Lifespan rarely is longer than 3 years (Sublette et al. 1990).
