PCT were extirpated from their historical habitat due to introduced trout but exist in formerly fishless areas of the Silver King Creek drainage and four out-of-basin watersheds above fish passage barriers. Genetic management plan and genetics report for the Paiute cutthroat trout (Oncorhynchus clarkii seleniris). During this phase of restoration project, the stream was treated with rotenone (a piscicide) to remove non-native trout from Silver King Creek and associated tributaries between Snodgrass Creek and Llewellyn Falls. Five different trout species have been moved into and around the Silver King drainage, including PCT, Lahontan Cutthroat Trout, California Golden Trout, Rainbow Trout, and Brook Trout. PCT is one of the most imperiled native fish in California, due to loss of genetic diversity and habitat fragmentation. Paiute cutthroat trout O. c. seleniris (J. O. Snyder, 1933) Endemic to eastern Sierra Nevada Mountains; it is designated as threatened (1975). Paiute cutthroat are often called the rarest trout in North America. The photos below are the native lake form of Lahontan Cutthroat Trout in Pyramid Lake. Lahontan Cutthroat Trout Photo Gallery. The introduction of non-native trout into their historic range was a major cause of the PCT’s decline. They are all completely isolated from each other, so there can be no genetic exchange or recolonization after a catastrophic event, such as a large forest fire. The historic distribution of the Paiute cutthroat trout is limited to 14.7 kilometers (9.1 miles) of habitat in Silver King Creek from Llewellyn Falls downstream to Silver King Canyon as well as the accessible reaches of three small named tributaries: Tamarack Creek, Tamarack Lake Creek, and the lower reaches of Coyote Valley Creek downstream of barrier falls. With ongoing conservation projects being implemented, we expect this Historically, recreational fishing was a threat to PCT. Their historic range is an 11-mile long stretch of a single creek in the eastern Sierra Nevada near the California-Nevada border. Paiute cutthroat trout, O. c. seleniris, closely resemble the Lahontan cutthroat with a dull coloration, but unlike the Lahontan, Paiute cutthroat lack spots. The Paiute Cutthroat Trout (PCT) Oncorhynchus clarkii seleniris is classified as a subspecies within the greater Cutthroat Trout O. clarkii ssp. The Paiute Cutthroat Trout was one of the first species added to the Endangered Species List in 1967, and its reintroduction marks decades of hard work from conservationists. To create additional refuge populations, PCT were introduced by various individuals and the California Department of Fish and Wildlife (CDFW) into other headwater tributaries within the Silver King Creek watershed, as well as four stream systems outside that basin. The Paiute cutthroat trout was one of the first species in the nation listed under the federal Endangered Species Act in the 1960s. Posted on September 29, 2019 by Cereghino.

Native to Silver King Creek and tributaries in the headwaters of the East Fork Carson River drainage. The PCT is a federally-listed threatened species, and this restoration work is a major component of the recovery effort. PCT have a high likelihood of extirpation in their native range within the next 50 years without continued commitment to Believed to be the rarest trout in the world, the Paiute cutthroat almost became extinct before it was discovered. Young-of-the-year fish rear in mainstem shoals or backwaters, and often move into intermittent tributary streams until they reach about 50 mm in length. Erosion made the gorge impassable to trout swimming upstream and populations got trapped and needed to … Advertisement "This is one of the world's rarest trout on earth.

Paiute Cutthroat Trout Distribution. The Paiute cutthroat trout, Oncorhynchus clarki seleniris, is a subspecies of the cutthroat trout, growing 10-12 in (25-30 cm). Rotenone compounds have been used for centuries, all over the world, to stun and kill fish. To protect this subspecies and its habitat, grazing is no longer allowed in the upper Silver King Creek basin above Snodgrass Creek. Another reintroduction is scheduled to take place Photo courtesy of William Somer, California Department of Fish and Game.

To increase their protection, progeny of the 1912 shepherds’ transplant were planted in other fishless waters of the Sierra Nevada, outside the species’ historic range, creating out-of-basin refuge populations. The Paiute Cutthroat Trout Restoration Project was developed to eliminate threats from non-native fish, restore the PCT to its historical habitat, and ensure the minimum habitat requirements for long-term survival. Paiute Cutthroat Trout have the most restricted range of any of the generally recognized sub-species of cutthroat trout. Silver King Creek is part of the Paiute cutthroat trout's historic range but is currently populated by hybridized non-native trout that could threaten the existence of pure Paiute cutthroat trout located above Llewellyn Falls if these populations were inadvertently mixed. In short sections of streams (called “reaches”), both the population size and habitat diversity may be inadequate for the species to survive, long-term.

The U.S. Environmental Protection Agency has concluded that rotenone use for fish control does not present a threat or risk of unreasonable adverse effects to humans or the environment. For more information on rotenone visit the American Fisheries Society Rotenone Stewardship Program. Chemical treatment was the preferred alternative identified in the Paiute Cutthroat Trout Restoration Project Final EIR/EIS. The present distribution of Paiute cutthroat trout consists of a population in Silver King Creek above Llewellyn Falls and tributary populations in Fly Valley, Four Mile Canyon Creek, Coyote Valley, and Corral Valley creeks, and four self-sustaining, pure populations outside the native drainage in the North Fork of Cottonwood and Cabin creeks (Inyo National Forest), and Stairway and Sharktooth creeks (Sierra National Forest).

Their historic range is an 11-mile long stretch of a single creek in the eastern Sierra Nevada near the California-Nevada border. This puts them at risk of hybridization with non-native trout and exposes them to the harmful effects of wildfires, drought, and climate change. Somer says, genetic analysis has not just enabled the more precise identification of the Paiute cutthroat trout from nonnative species but genetic techniques have also deepened knowledge about the history of the threatened fish. Small isolated populations exhibit founder effects, inbreeding depression, and are extremely vulnerable to extinction. Summit Lake in remote northwest Nevada is home to the only self-sustaining, robust, lake population of Lahontan Cutthroat Trout, North America’s largest freshwater native trout species.
