The cutthroat trout (Oncorhynchus sp.) is a group of four fish species [4] [5] of the family Salmonidae native to cold-water tributaries of the Pacific Ocean, Rocky Mountains, and Great Basin in North America. These four species are the Coastal (O. clarkii), Westslope (O. lewisi), Lahontan (O. henshawi), and the Rocky Mountain (O. virginalis
Historically, cutthroat trout was considered one species (Oncorhynchus clarkii).[2] [9] However, recent genetic, taxonomic, and geologic [10] evidence has determined that cutthroat trout should be divided into four species, with each (except for the coastal cutthroat) having multiple subspecies corresponding to the evolutionary lineages [11] found within major river basins.
The record-size cutthroat trout of any subspecies was a Lahontan caught in Pyramid Lake, weighing 41 lb (18.6 kg), although anecdotal and photographic evidence exists of even larger fish from this lake.
The Bozeman National Fish Hatchery was a key player in the recovery of the greenback cutthroat trout. [ 8 ] [ 9 ] [ 10 ] In 2012, a genetic study that compared DNA samples both from modern populations and historical samples dating back to the 19th century revealed that the only remaining population of pure greenback cutthroat trout is found in ...
Angling for trout has been a pastime in the park since its creation and trout species dominate the fish inhabiting the park. When Yellowstone National Park was created in 1872, 40% of the park's waters were barren of fish, including most alpine lakes and rivers above major waterfalls. Only 17 of 150 lakes held fish.

[10] [13] The ruling was challenged by the Center for Biological Diversity, however, and the U.S. Fish and Wildlife Service will reevaluate the species' candidacy. [14]: 41570 The Rio Grande cutthroat trout evolved in New Mexico as a member of a native fish assemblage that included the longnose dace, the Rio Grande chub and the Rio Grande sucker.
