Ictalurus pricei, the Yaqui catfish, is a species of North American freshwater catfish native to Mexico and Arizona.
The coloration of the Yaqui catfish is dark gray to black dorsally, and white to grayish beneath. The barbells of the catfish are jet-black except on the chin, where they are gray to whitened. The Yaqui catfish body is usually profusely speckled". [2] A reddish coloration on the catfish is prominent beneath the head, as well as on the fins and tail. The adult size is up to 57.0 cm. [3]
I. pricei was named in honour of William W. Price. [4]
The Yaqui catfish historically occurred in San Bernardino Creek as far up as San Bernardino Ranch, Arizona. An introduced population of catfish existed in the Monkey Springs Reservoir system near Patagonia, Arizona, from 1899 until the 1950s. The stock presumably came from the Rio Sonora basin of Sonora, Mexico, where the species still lives. [5] A small population of 350 fish has been reintroduced into the Rio Yaqui on the northernmost portion of the San Bernardino National Wildlife Refuge in November 1997. [5]
Yaqui catfish are found primarily in ponds or streams, primarily in larger rivers, but also in small streams, where they prefer quiet, clear pools. The catfish are most common in larger rivers in areas of medium to slow currents over sand/rock bottoms. [6] Streams flow intermittently in the dry season, and the catfish seeks refuge in permanent, often spring fed pools. [3]
Yaqui catfish survived in San Bernardino Creek until spring flows diminished because of groundwater pumping causing the creek to dry up. The remaining habitat at San Bernardino Creek was severely trampled by livestock, making it uninhabitable. [7] The catfish were introduced in 1899 into the Santa Cruz River system (in a reservoir fed by Monkey Spring), where they persisted until the 1950s. A small population of 350 fish has been reintroduced into the Rio Yaqui on the northernmost portion of the San Bernardino National Wildlife Refuge in November 1997, but outside the San Bernardino refuge, they have become extinct from United States waters. [2]
Activities known to be detrimental to the Yaqui catfish populations are the dewatering of habitats through stream usage and rerouting, stream impoundment, channelization, domestic livestock grazing, timber harvesting, mining, road construction, polluting, and stocking non-native species.
Threats: aquifer pumping, reduction in stream flows, water diversion, drought, hybridization, and competition and predation by non-native fishes
Management needs: protect San Bernardino aquifers, and Leslie Creek and Black Draw watersheds to ensure adequate perennial flow, ameliorate effects of non-native fishes, reintroduce into suitable habitats within historical range, stabilize and protect populations in Mexico
The roundtail chub is a cyprinid fish in the genus Gila, of southwestern North America. It is native to the Colorado River drainage basin, including the Gila River and other tributaries, and in several other rivers. It is part of the “robusta complex”, which includes the Gila robusta robusta, G.r. grahami, and G.r. seminuda.
The Yaqui sucker is a species of ray-finned fish in the family Catostomidae. It is found the Aridoamerica region of northern Mexico and south-western United States. Catostomus bernardini or Yaqui sucker belongs to the family Catostomidae. The Yaqui sucker is related to the Sonora sucker and could possibly be a subspecies of the Gila sucker.
The beautiful shiner is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and Arizona and New Mexico in the United States. It is one of 22 species of Cyprinella found in North America.
The Sonora chub is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and the United States.
The Gila chub is a species of ray-finned fish in the family Cyprinidae. It is found in Mexico and the United States. The Gila chub is closely related to the roundtail chub. This species is commonly found in association with the Gila topminnow, the desert and Sonora sucker, and the longfin and speckled dace.
The Yaqui chub is a species of freshwater fish in the family Cyprinidae. It is found in northern Mexico and the United States. The Yaqui chub is a medium-sized minnow fish that historically occurred in streams of Rios Matape, Sonora, and the Yaqui systems of Sonora, Mexico. It is one of the five species of the genus Gila in Arizona. The Yaqui chub is closely related to G. ditaenia, and G. orcutti ; and shares several physical characteristics with the G. orcutti, but proves different by having a black wedge near the base of the caudal fin.
The San Bernardino springsnail is an endangered species of freshwater snail in the family Hydrobiidae. This species is endemic to a small number of springs in the USA and northern Mexico.
The Rio San Bernardino, or San Bernardino River, begins in extreme southeastern Cochise County, Arizona, and is a tributary of the Bavispe River, in Sonora, Mexico.
The Rio Bavispe or Bavispe River is a river in Mexico which flows briefly north then mainly south by southwest until it joins with the Aros River to become the Yaqui River, eventually joining the Gulf of California.
Leslie Canyon National Wildlife Refuge is a National Wildlife Refuge of the United States located in Arizona. The 2,770-acre (11.2 km2) refuge was established in 1988 to protect habitat for the endangered Yaqui Chub and Yaqui Topminnow. The refuge also protects a rare velvet ash-cottonwood-black walnut gallery forest.
The San Bernardino National Wildlife Refuge is located on the U.S.-Mexico border in Cochise County, Arizona. Situated at 3,720 to 3,920 feet (1,130–1,190 m) elevation in the bottom of a wide valley, the refuge encompasses a portion of the headwaters of the Yaqui River, which drains primarily western Chihuahua and eastern Sonora, Mexico. The 2,309-acre (9.34 km2) ranch was acquired by the U.S. Fish and Wildlife Service in 1982 to protect the water resources and provide habitat for endangered native fishes.
The Yaqui longfin dace is a small fish of the American Southwest and northern Mexico, and considered a form of the longfin dace. It is often referred to as Agosia chrysogaster sp 1.
The Mexican stoneroller is a species of fish native to Arizona and Texas in the United States and parts of adjacent Mexico. It belongs to the carp family, Cyprinidae. There are three other species in this genus, Campostoma anomalum, Campostoma oligolepis, and Campostoma pauciradii, which are morphologically similar.
The headwater chub is a species of fish in the family Cyprinidae. It is found in Arizona and New Mexico.
The Sonora Sucker, Catostomus insignis, is a medium-sized catostomid fish with 16 other species in the genus scattered throughout North America. This species is remarkably similar in appearance to the Yaqui Sucker.
The Yaqui topminnow is a species of fish in the family Poeciliidae. Its scientific name is Poeciliopsis sonoriensis; it is also sometimes considered a subspecies of Poeciliopsis occidentalis as P. o. sonoriensis. This fish is native to Mexico and the United States, with a few native and introduced populations persisting in Arizona in the United States, and a number of populations still extant in northern Sonora, Mexico.
The San Bernardino Valley of Arizona is a 35 mi (56 km) northeast-by-southwest trending valley in extreme southeast Cochise County, Arizona. The north end of the valley merges into the northwest-by-southeast trending San Simon Valley; both merge in western perimeter Hidaldgo County, New Mexico. The valley is an asymmetric graben.
Whitewater Draw, originally Rio de Agua Prieta, [Spanish: river of dark water], is a tributary stream of the Rio de Agua Prieta in Cochise County, Arizona. It was called Blackwater Creek by Philip St. George Cooke when his command, the Mormon Battalion, camped at a spring on its course on December 5, 1846.
