Until the 1960s, populations of westslope cutthroat trout and Yellowstone cutthroat trout were lumped into one subspecies; Salmo clarkii lewisii. Overall, we estimated that lake trout consumed over 38% of reintroduced Lahontan cutthroat trout (mean number consumed = 7,736 fish; 95% CI = 4,388–14,534 fish).

Interesting research from California Department of Fish and Wildlife about the fate of Lahontan cutthroat trout, which are rare to California waters. , Throughout their native and introduced ranges, cutthroat trout vary widely in size, coloration and habitat selection. Lake Lahontan was a large endorheic Pleistocene lake of modern northwestern Nevada that extended into northeastern California and southern Oregon.The area of the former lake is a large portion of the Great Basin that borders the Sacramento River watershed to the west.. These hatcheries not only produced stocks of the Yellowstone cutthroat trout (O. c. bouvierii) for the park, but also took advantage of the great spawning stock of cutthroat trout to supply eggs to hatcheries around the U.S. Juvenile cutthroat trout typically mature in three to five years. Needham was the first to recognize that the Lahontan Cutthroat Trout (LCT) of adjacent Independence Lake was the last self-reproducing native and genetically pure population of this species, the largest trout in the world. Pyramid Cutthroat Outfitters is a Fly fishing guiding service on the beautiful and mysterious Pyramid Lake Nevada and home to the Lahontan Cutthroat Trout. The length and weights of mature inland forms vary widely depending on their particular environment and availability of food. That’s a new certified weight state record.  Most populations stay in fresh water throughout their lives and are known as nonmigratory, stream-resident or riverine populations. Yellowstone National Park was established in 1872. Pyramid Cutthroat Outfitters is a Fly fishing guiding service on the beautiful and mysterious Pyramid Lake Nevada and home to the Lahontan Cutthroat Trout. Portions of the westslope cutthroat trout's (O. c. lewisi) range overlap with the Columbia River redband trout (O. m. gairdneri), but the majority of its native range is in headwater tributary streams above major waterfalls and other barriers to upstream migration. The common name "cutthroat" refers to the distinctive red coloration on the underside of the lower jaw. Fish and Wildlife Service, Lahontan National Fish Hatchery Complex, 1340 Financial Boulevard, Suite 234, Reno, Nevada, 89502 USA, Department of Watershed Sciences, Utah State University, 5210 Old Main, Logan, Utah, 84321 USA.

It … Juvenile Movement among Different Populations of Cutthroat Trout Introduced as Embryos to Vacant Habitat. From the Yellowstone cutthroat trout fishery in Yellowstone National Park, the unique Lahontan cutthroat trout fishery in Pyramid Lake in Nevada, and the small stream fisheries of the westslope cutthroat trout to saltwater angling for sea-run cutthroat trout on the Pacific coast, cutthroat trout are a popular quarry for trout anglers throughout their ranges.  Then, in 1994, park officials discovered lake trout (Salvelinus namaycush) in Yellowstone Lake. 17-pound record … Spawning begins when water temperatures reach 43 to 46 °F (6 to 8 °C). Jordan Rodriguez was fishing at the Grasmere Reservoir on Dec. 12, where he landed a 20-inch Lahontan cutthroat trout. Evaluation of Potential Translocation Sites for an Imperiled Cyprinid, the Hornyhead Chub. Cutthroat trout were the first New World trout encountered by Europeans when in 1541, Spanish explorer Francisco de Coronado recorded seeing trout in the Pecos River near Santa Fe, New Mexico. The Lahontan Cutthroat Trout historically occurred in the Great Basin of Nevada including portions of southern Idaho and Oregon as well as eastern California. Since 2002, 76,547 Lahontan cutthroat trout have been reintroduced into Fallen Leaf Lake, California; we used creel surveys, diet data, mark–recapture methods, bioenergetics modeling, and netting data across seasons to evaluate the habitat use, growth, and relative abundance of Lahontan cutthroat trout and the abundance, diet, habitat use, and predation by nonnative species. Cutthroat trout spawn in the spring and may inadvertently but naturally hybridize with rainbow trout, producing fertile cutbows. In the Truckee River system, only Independence Lakehas continuously harbored its historic native Lahonta… Their coloration can range from golden to gray to green on the back. In saltwater estuaries and along beaches, Coastal cutthroat trout feed on small fish such as sculpins, sand lance, salmon fry and herring. A population of Yellowstone cutthroat trout purportedly has been established in Lake Huron. , Cutthroat trout usually inhabit and spawn in small to moderately large, clear, well-oxygenated, shallow rivers with gravel bottoms. The Lahontan cutthroat trout is one subspecies of the wide-ranging cutthroat trout species (O. clarki) that includes at least 14 recognized forms in the western United States. The Lahontan cutthroat trout is endemic or native to the Lahontan basin of northern Nevada, eastern California, and southern Oregon.

They average about one and one-half pounds each and are of the salmon myhiss [sic] variety—a catch of 100, three or four hours before sundown, is not unfrequent. This area is now known as the Fishing Bridge Historic District. Fishing season runs from October 1st to June 30th, with the peak season being December-April. With bioenergetics modeling, however, we estimated that lake trout consumed considerable amounts of salmonid biomass during this period (mean biomass = 3,137 kg; 95% CI = 1,779–5,893 kg), which greatly exceeded the biomass of Lahontan cutthroat trout reintroduced in 2006.  Some coastal populations of the coastal cutthroat trout (O. c. clarkii) are semianadromous, spending a few months in marine environments to feed as adults and returning to fresh water from fall through early spring to feed on insects and spawn.  Ranges of some subspecies, particularly the westslope cutthroat trout (O. c. lewisi) have been reduced to less than 10 percent of their historic range due to habitat loss and introduction of non-native species. They reproduce in clear, cold, moderately deep lakes. Managers implemented catch and release, which required anglers to return their catches to the lake, and they terminated hatchery operations in the park which allowed the cutthroat trout to recover. 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. In the lower reaches of larger rivers, anglers in drift boats float the rivers searching for trout along the wooded shorelines. They are native to the alluvial or freestone streams that are typical tributaries of the rivers of the Pacific basin, Great Basin and Rocky Mountains.

Although cutthroat trout are not native to Arizona, they are routinely introduced by the Arizona Game and Fish Department into high mountain lakes in the White Mountains in the northeastern region of that state.  Depending on subspecies, strain and habitat, most have distinctive red, pink, or orange linear marks along the underside of their mandibles in the lower folds of the gill plates. Most subspecies of cutthroat trout are highly susceptible to whirling disease, although the Snake River fine-spotted cutthroat trout (O. c. behnkei) appears to be resistant to the parasite.
