Soldwedel, personal communication); the Mimbres, Rio Grande, Pecos, San Juan, Little Colorado, San Francisco,San Juan, and Gila drainages in New Mexico (Koster 1957; Tyus et al. 1982; Sublette et al. 1990; Platania 1991; Springer 2005); the Susquehanna drainage in New York (T.

Means of Introduction: Intentionally stocked for sport fishing and food. The first introductions in the Colorado River took place in 1892-1893 or in 1906 (Miller and Alcorn 1946). They had become established throughout the Colorado basin by the early 1900s (Holden and Stalnaker 1975). The earliest stocking record for the Yampa River is from 1944 and involved 34,200 fingerling catfish (Tyus 1998). The introductions into Silver Lake and the Charles River in Massachusetts involved albino fish from the aquarium trade (Cardoza et al. 1993).

Status: Established in most waters where introduced.

Impact of Introduction: The Channel Catfish hybridizes with the threatened Yaqui catfish I. pricei in Mexico (U.S. Fish and Wildlife Service 1994). Colorado pikeminnow Ptychocheilus lucius, an endangered species, have been documented to choke on introduced Channel Catfish when attempting to eat them (McAda 1983; Pimental et al. 1985; U.S. Fish and Wildlife Service 1990). Jenkins and Burkhead (1994) speculated that introduced Channel Catfish may have contributed to the demise of an isolated population of trout-perch Percopsis omiscomaycus in the Potomac River in Virginia and Maryland. Introduced Channel Catfish may exert a major negative effect on populations of various endangered species. For instance, this species is known to prey on small and large endangered humpback chub Gila cypha in the Little Colorado River thereby limiting recruitment and also increasing adult mortality (Marsh and Douglas 1997). There is also evidence that this introduced catfish preys heavily on juveniles of razorback sucker Xyrauchen texanus that had been reintroduced into the Gila River of Arizona (Marsh and Brooks 1989). Introduced predatory fishes, including the Channel Catfish, may be partially responsible for the decline of the Chiricahua leopard frog Rana chiricahuensis in southeastern Arizona (Rosen et al. 1995) and have been shown to reduce the abundance and diversity of native prey species in several Pacific Northwest rivers (Hughes and Herlihy 2012).

Channel Catfish predation on crayfish resulted in a great loss of crayfish density in mesocosm experiments, and is likely the cause of native crayfish population decline in natural habitats where the Channel Catfish has been introduced (Adams 2007).

Remarks: Tyus et al. (1982) gave a distribution map for this species in the upper Colorado basin. Channel Catfish have also been stocked in many native areas including Arkansas (Robison and Buchanan 1988); Illinois (Burr, personal communication); Nebraska (Jones 1963). Harlan et al. (1987) stated that stocking in Iowa has widened this species' distribution. Cross and Collins (1995) mapped the species in every county in Kansas. Cross (1967) indicated a much more restricted distribution in the state and did not include every county. Presumably the more recent map indicates the species had been introduced to new locations since the 1967 publication. Cross (1967) also stated that it had been stocked in many lakes and ponds in the state.  Griffiths (1939) reported that the Channel Catfish was found in the ladders of the Bonneville Dam but no specimens were obtained. If introduction did occur it is though that they were unsuccessful.

According to Springsteen (2010), the Channel Catfish was the first species to be raised in commercial aquaculture for food purposes in the US.  Before that point, other species including tilapia and carp were raised in Egypt and China for sport.  The species was farmed in the Mississippi Delta region during the 1950s.
