(S. F. Baird & Girard in Girard, 1854)

The thicktail chub (Gila crassicauda) was a type of minnow that inhabited the lowlands and weedy backwaters of the Sacramento and San Joaquin Rivers in the Central Valley of California. It was once abundant in lowland lakes, marshes, ponds, slow-moving stretches of river, [2] and, during years of heavy run-off, the surface waters of San Francisco Bay. [2] The thicktail chub was one of the most common fish in California. [2] Within Native American middens it represented 40% of the fish. [3]

The chub was a favored food of the native Indian peoples of Clear Lake and the Central Valley before being heavily exploited by commercial fishermen supplying the San Francisco market. [2] A heavy-bodied fish with a thick tail and a small, cone-shaped head, the backs of the thicktail chub ranged in color from greenish brown to purplish black, while the sides and belly were yellow. It could reach a length of nearly ten inches. Although little is known about its behavior, it was probably carnivorous, feeding on small fish and invertebrates.

The primary cause of the thicktailed chub's extinction was the conversion of much of the Central Valley to agricultural use. Most of its habitat was destroyed by the drainage of sloughs and marshes, dam-building, and water diversion for irrigation. All this resulted in the loss of the sluggish water the species preferred. Competition from exotic species also contributed to its extinction. The last known example was caught on April 16, 1957. [2]

Cypriniformes Order of fishes

Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. This order contains 11-12, although some authorities have designated as many as 23, families over 400 genera, and more than 4,250 species, with new species being described every few months or so, and new genera being recognized frequently. They are most diverse in southeastern Asia, and are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.

Tulare Lake Freshwater dry lake in the southern San Joaquin Valley, California, United States

Tulare Lake is a freshwater dry lake with residual wetlands and marshes in the southern San Joaquin Valley, California, United States. After Lake Cahuilla disappeared in the 17th century, Tulare Lake was the largest freshwater lake west of the Mississippi River and the second-largest freshwater lake entirely in the United States, based upon surface area. A remnant of Pleistocene-era Lake Corcoran, Tulare Lake dried up after its tributary rivers were diverted for agricultural irrigation and municipal water uses.

Gila River

The Gila River is a 649-mile (1,044 km)-long tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly 60,000 square miles (160,000 km2) that lies mainly within the U.S., but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century.

Coyote Creek (Santa Clara County)

Coyote Creek is a river that flows through the Santa Clara Valley in California, United States.

Suisun Marsh Largest brackish water marsh on west coast of US

Located in northern California the Suisun Marsh has been referred to as the largest brackish water marsh on west coast of the United States of America. The marsh land is part of the San Francisco Bay tidal estuary, and subject to tidal ebb and flood. The marsh is home to many species of birds and other wildlife, and is formed by the confluence of the Sacramento and San Joaquin rivers between Martinez and Suisun City, California and several other smaller, local watersheds. Adjacent to Suisun Bay, the marsh is immediately west of the legally defined Sacramento-San Joaquin Delta as well as part of the San Francisco Bay estuary.

<i>Gila</i> (fish) Genus of fishes

Gila is a genus of fish belonging to the family Cyprinidae, native to the United States and Mexico. Species of Gila are collectively referred to as western chubs. The chiselmouth is a close relative, as are members of the genus Siphateles. Several members of the genus are endangered or extinct due to loss of habitat causing by diversion or overuse of water resources, particularly in the western United States.

Utah chub Species of fish

The Utah chub is a cyprinid fish native to western North America, where it is abundant in the upper Snake River and throughout the Lake Bonneville basin.

The tui chub is a cyprinid fish native to western North America. Widespread in many areas, it is an important food source for other fish, including the cutthroat trout.

Arroyo chub Species of fish

The arroyo chub is a cyprinid fish found only in the coastal streams of southern California, United States.

<i>Lavinia exilicauda</i> Species of fish

The hitch is a cyprinid fish endemic to central California, and was once very common. The name is derived from the Pomoan word for this species.

Tule perch Species of fish

The tule perchHysterocarpus traskii is a surfperch (Embiotocidae) native to the rivers and estuaries of central California, United States of America. It is the sole member of its genus, and the only freshwater surfperch.

Roundtail chub Species of fish

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.

Bonytail chub Species of fish

The bonytail chub or bonytail is a cyprinid freshwater fish native to the Colorado River basin of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming in the southwestern United States; it has been extirpated from the part of the basin in Mexico. It was once abundant and widespread in the basin, its numbers and range have declined to the point where it has been listed as endangered since 1980 (ESA) and 1986 (IUCN), a fate shared by the other large Colorado basin endemic fish species like the Colorado pikeminnow, humpback chub, and razorback sucker. It is now the rarest of the endemic big-river fishes of the Colorado River. There are 20 species in the genus Gila, seven of which are found in Arizona.

The Mexican dace, or Mexican chub, is an extinct species of ray-finned fish in the family Cyprinidae. It was found only in Mexico, in the canals and streams of the Valley of Mexico. It is estimated to have become extinct circa 1983. The extinction of this species coincided with the drying of water bodies in the valley. This drying was a result of the increasing demands placed on the water resources of the valley by agriculture, as well as by the growth of Mexico City and its suburbs.

Gila chub Species of fish

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.

Yaqui chub Species of fish

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.

Headwater chub Species of fish

The headwater chub is a species of fish in the family Cyprinidae. It is found in Arizona and New Mexico.

The Virgin chub or the Virgin River chub is a medium-sized, silvery minnow, generally less than 15 cm long and reaching lengths of 25 cm. The back, breast, and part of the belly are embedded with small scales, naked in some individuals. The length of the head divided by the depth of the caudal peduncle typically results in a ratio of 4.0 to 5.0. The scales are typically lacking basal radii or are with extremely faint lines.

Rio Grande chub Species of fish

The Rio Grande chub is a cyprinid fish endemic to the United States. It inhabits the upper Rio Grande and Pecos River systems in Colorado, New Mexico and Texas. The Rio Grande Chub is native to most of its current range including all three of the states it can be found in. There are non-native populations that currently inhabit Coyote Creek, the Mora River, the Sapello River and other areas in New Mexico. There are currently no studies showing how the Rio Grande Chub is impacting waterways in its non-native range. It has also been proposed that this fish is native to the Canadian River in New Mexico but this has not been proven. It is possible it was introduced there. Natural hybridization can occur between the Rio Grande Chub and the Longnose dace.
