The bonytail chub or bonytail (Gila elegans) 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. Coloration is typically grey dorsally, fading to white ventrally, with yellowish pigmentation … conditions to assess whether Humpback Chub growth characteristics may have responded to changes in water temperature. Prepared in cooperation with the U.S. A fleshy dorsal hump develops behind the head as the fish matures. Kaeding et. The humpback chub was listed as endangered species by the U.S. Humpback chub live as long as 30 years or more and reach lengths of up to 20 inches (500 mm). Its name describes the fish as an elegant swimmer and member of the “chub” group of minnows. Each population consists of a discrete group of fish, geographically separated from the other populations, but with some exchange of individuals. The humpback chub has a streamlined body, with a concave skull on its dorsum.

Yard 2, and Charles B. Yackulic 2 6 7 1Ecometric Research Inc., 3560 W 22 nd Ave., Vancouver, BC V6S 1J3, Canada. “The humpback chub has many traits that enable individuals to be resilient in the face of environmental or demographic stochasticity, including a long life span, high reproductive potential, use of habitats and water quality that are arduous to other species, adaptation to a wide variety of flow and thermal regimes, and a variable omnivorous diet,” according to the proposal. The humpback chub (Gila cypha) is an unusual-looking member of the minnow family that is endemic, or native to the Colorado River basin. Physical retention of randomly placed particles simulating the movement of juvenile humpback chub in the study reaches tended to decline with increasing discharge, but the pattern varied considerably due to differences in the local morphology among reaches and the type of swimming behaviour modelled. tentatively identified as humpback chub by physical characteristics (Gila. Earliest collections of humpback chub are anecdotal and relate to early explorations of the Colorado River Basin that pre-date the species description in 1946. In addition to the change in habitat, the rainbow trout and other introduced species predate on the chub. The body is not as streamlined as other rorquals, but is quite round, narrowing to a slender peduncle (tail stock). 0000000893 00000 n The bonytail has a gray or olive-colored back, silver sides, and a white belly. Of the five native fish species that remain in the Grand Canyon, only the speckled dace is common in the park and it lives primarily in the tributaries. Total embryonic mortality occurred at 5, 10, and 300C (410, 500, and 860F). The most striking characteristic of these large silver minnows is the pronounced fleshy hump located behind their heads. The breeding male's belly turns bright orange-red. They are 15m long. The hump may be protective, making the fish difficult eating for predators.

Humpback whales are black or gray except for their flippers and the undersides of their flukes, which are white. %%EOF The distribution and abundance of the humpback chub in the Colorado River below Glen Canyon Dam have been severely restricted by physical changes in the river. Ripe males aggregated in areas of complex habitat structure with high angular variation in bottom profiles and were associated with deposits of clean gravel, and spawning involves contact with gravel substrates, where semi-adhesive eggs are deposited and fertilized (Gorman and Stone 1999). An extensive amount of literature has been produced on the humpback chub. Physical characteristics that can help distinguish rainbow trout include dark spots on a light body, continuous spotting throughout the body, and often a “rainbow” horizontal reddish stripe. Cool facts. The narrow tail terminates in a V-shaped caudal fin.
