The cutbow (Oncorhynchus clarkii × mykiss) is an interspecific fertile hybrid between rainbow trout (Oncorhynchus mykiss) and cutthroat trout (O. clarkii).While natural separation of spawning habitat limited hybridization in most native populations of rainbow and cutthroat trout, introduction of non-native hatchery-raised rainbow trout into native cutthroat trout range increased hybridization ...
A Cutbow (Oncorhynchus clarki x mykiss) is a fertile hybrid between a rainbow trout (Oncorhynchus mykiss) and a cutthroat trout (O. clarki). While cutbow hybrids may occur naturally, most native populations of rainbows and cutthroats were separated by geography or habitat.
The tiger trout (Salmo trutta × Salvelinus fontinalis) is a sterile, intergeneric hybrid of the brown trout (Salmo trutta) and the brook trout (Salvelinus fontinalis). Pronounced vermiculations in the fish's patterning gave rise to its name, evoking the stripes of a tiger .
The rainbow trout (Oncorhynchus mykiss) is a species of trout native to cold-water tributaries of the Pacific Ocean in North America and Asia. The steelhead (sometimes called steelhead trout) is an anadromous (sea-run) form of the coastal rainbow trout (O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to freshwater to spawn after living two to three years ...
While fine-spotted x rainbow trout crosses are observed in the South Fork of the Snake River in Idaho, they are infrequently encountered and appear to be hatchery hybrids. Conversely, Yellowstone x rainbow crosses are common; the " cutbows " of Yellowstone Park in the Lamar River drainage are natural hybrids.
This hybrid generally bears similar coloration and overall appearance to the cutthroat trout, usually retaining the characteristic orange-red slash. Cutbow hybrids often pose a taxonomic difficulty when trying to distinguish any given specimen as a rainbow or cutthroat trout. [64]
Jul. 16—Most rainbow trout swimming in Montana's waters are not native to the state — with the singular exception of the redband trout in the Kootenai drainage. While common throughout most of ...
The Gallatin River in the valley section has excellent [26] fly fishing for both rainbow and brown trout. Average rainbow size is 12 inches (300 mm). Brown trout average between 12 and 14 inches, although larger fish are often caught. [18] An unlimited number of brown or rainbow trout may be harvested daily.
