In inland populations, the introduction of rainbow trout from hatchery stocks have resulted in cutbow hybrids that continue to diminish the genetic purity of many cutthroat trout subspecies. Sea-run forms of coastal cutthroat trout average 2 to 5 pounds (0.9 to 2.3 kg). size of between 4" and 10" long (Trotter 2008). The introduction of hatchery-raised Yellowstone cutthroat trout into native ranges of other cutthroat trout subspecies, particularly the westslope cutthroat trout, has resulted in intraspecific breeding and diminished genetic purity of the westslope subspecies. [5] Until the 1960s, populations of westslope cutthroat trout and Yellowstone cutthroat trout were lumped into one subspecies; Salmo clarkii lewisii. management practices the Rio Grande cutthroat will begin staging a comeback nonnative trout throughout the Rio Grande basin and have also had a substantial She ordered the agency to explain why it considers isolated trout populations of less than 2,500 to be stable.

In a federal lawsuit filed by the Tucson, Arizona-based Center … [84] As Pyramid Lake has a very shallow shoreline, anglers use ladders to stand comfortably in 3 to 4 feet (0.9 to 1.2 m) of water and cast to trout cruising along shoreline breaks. Rio Grande cutthroat trout are light rose to red-orange on the sides and pink or yellow-orange on the belly. Toward the tail, these spots come together to form club shapes. The fish is found in less than 7% of its historic range. in comparison to other species. [32], Although members of Oncorhynchus, the Pacific trout/salmon species, three subspecies—the westslope (O. c. lewisi), the greenback (O. c. stomias) and Yellowstone cutthroat trout (O. c. bouvierii)—evolved populations east of the Continental Divide in the upper Missouri River basin, upper Arkansas and Platte River basins and upper Yellowstone River basin, each which drain into the Atlantic basin via the Mississippi River (in 2005, researchers published a report stating that a natural distribution of (O. mykiss), the Conchos trout, is also located in an Atlantic basin drainage[37]). [41] Cutthroat trout were introduced into Lake Michigan tributaries in the 1890s and sporadically in the early 20th century, but never established wild populations. Rio Grande cutts are another great success story amongst a … the ESA. For decades, cutthroat trout … the introduction of nonnative fish. The cutthroat trout (Oncorhynchus clarkii) is a fish species of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. While rainbow trout are the most problematic [32] Fisheries biologist Robert J. Behnke attributes the extinction of the yellowfin cutthroat trout (O. c. macdonaldi) and Alvord cutthroat trout (O. c. alvordensis) subspecies to the introduction of non-native rainbow trout. Mining, In 2006, the Pyramid Lake strain of Lahontan cutthroat trout were reintroduced into the lake. The stream resident form of this trout is the only form remaining today, a pink or orange color along their lateral line and the gill plates are Native cutthroat trout species are found along the Pacific Northwest coast from Alaska through British Columbia into northern California, in the Cascade Range, the Great Basin and throughout the Rocky Mountains including southern Alberta.

This decrease is attributed to drought, … 2008). The Pecos River form is distinguished by larger spots and more scales in the lateral series. [31] Lake-resident cutthroat trout are usually found in moderately deep, cool lakes with adequate shallows and vegetation for good food production. An understanding of the upper thermal tolerance of Rio Grande Cutthroat Trout is important for developing water temperature standards and for … those found in streams without brown trout. Previously, it was believed that the species also lived in the Arkansas River drainage, but the new genetic evidence suggests otherwise. [47] At least three subspecies are confined to isolated basins in the Great Basin and can tolerate saline or alkaline water.

In fresh water they consume the same diet as stream resident trout—aquatic insects and crustaceans, amphibians, earthworms, small fish and fish eggs. Many RGCT populations in New Mexico are managed as “Special Trout Waters.” Certain RGCT conservation populations are catch-and-release … Their coloration can range from golden to gray to green on the back.

[39] Scientists speculate that there are several mountain passes associated with the headwaters of the Colorado River drainage and Arkansas/Platte River drainages that would have allowed migration of cutthroat trout east of the divide. Pure populations now only persist in about 75 small headwater streams. is native range has been reduced by 90 to 95 percent today, there are [7], In 1989, morphological and genetic studies indicated trout of the Pacific basin were genetically closer to Pacific salmon (Oncorhynchus species) than to the Salmos–brown trout (S. trutta) or Atlantic salmon (S. salar) of the Atlantic basin. across its native range in the future.

Degraded streams often have less streamflow, an altered hydrology, a lack of resting cover and food sources, and too many nutrients and sediment. [57] Scientists believe the westslope cutthroat trout will eventually be extirpated from the large lakes in Western Montana due to the trophic cascades resulting from lake trout and mysis shrimp introductions.
