The following list of known freshwater fish species, subspecies, and hybrids occurring in the U.S. state of Idaho is taken from Wydoski and Whitney (2003). Some scientific names have been updated or corrected. Asterisks denote introduced fishes. The list includes several anadromous species.

Fish: Cutthroat trout (Oncorhynchus clarkii) Native to Idaho, the cutthroat trout's name comes from the "distinctive red to orange slash" on the underside of its jaw. During an attempt to designate a state fish in 1988, critics of the cutthroat pointed out that the species was not found throughout the entire state.
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 Sunapee Lake strain of the Sunapee trout was discovered in 1977 when Kent Ball, of Idaho Fish and Game, discovered a char species living with brook trout in a mountain lake in Idaho. Analysis by Robert Benhke , Eric Wagner, and Steve Culver proved the species to be a presumably introduced population of Sunapee trout.
The Snake River fine-spotted cutthroat trout is a form of the cutthroat trout (Oncorhynchus clarkii) that is considered either as a separate subspecies O. c. behnkei, or as a variety of the Yellowstone cutthroat trout (O. c. bouvieri).
Tiger trout are a rare anomaly in the wild, as the parent species are relatively unrelated, being members of different genera and possessing mismatched numbers of chromosomes. [ 1 ] [ 2 ] [ 3 ] However, specialized hatchery rearing techniques are able to produce tiger trout reliably enough to meet the demands of stocking programs.
