Not native to Colorado. The largemouth bass resides in shallow water habitats such as reeds, water lilies, and other vegetation. Largemouth bass prefer no current and clear water lakes and ponds. Bass will feed on minnows, carp, trout, crawfish and any other species of fish that is available, even their own.
The Colorado Pikeminnow was once a species of fish that resided in much of the Colorado River Basin. Due to human impacts and the introduction of non-native fish species, the population has receded to the upper basin. According to the Native Aquatic Species Conservation in Arizona, the installation of dams has altered the fish's movement. [9]
The humpback chub (Gila cypha) is a federally protected fish that lived originally in fast waters of the Colorado River system in the United States.This species takes its name from the prominent hump between the head and dorsal fin, which is thought to direct the flow of water over the body and help maintain body position in the swift currents of the Colorado river.
In Colorado, there is a total of 18 hatcheries raising 30+ species of fish which Colorado Parks and Wildlife (CPW) operate. Twelve of these hatcheries are cold water facilities, two are warm water facilities, two are cold and warm water, and two are USFWS hatcheries. [3]

The Colorado pikeminnow, P. lucius, is the largest member of the genus, ranging from 4–9 lb (2–4 kg) in adult fish with occasional specimens up to 25 lb (11 kg). Historical and anecdotal reports of Colorado pikeminnows nearing 6 feet (1.8 m) in length and 80 lb (36 kg) in weight have been made.
Bonytail chubs were one of the first fish species to reflect the changes that occurred in the Colorado River basin after the construction of Hoover Dam; the fish was extirpated from the lower basin between 1926 and 1950. [8] They may still be found in the Green River of Utah and perhaps in the larger Colorado River water bodies. [5]
The introduction of non-native species such as brook trout (Salvelinus fontinalis), brown trout (Salmo trutta), and rainbow trout (O. mykiss) was also detrimental to the greenback cutthroat. The former two species competed with greenback cutthroats while the latter hybridized with it, creating cutbows. Other subspecies of cutthroat were ...
