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 ...
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 ...
Trout have been reared artificially for over 80 years. [23] Rainbow trout broodstocks are commonly manipulated to delay maturation and spawning time in order to provide eggs regularly and optimise supply. [5] Artificial selection has favoured larger fish due to evidence of correlations between fish size and fecundity. [15]
The Athabasca rainbow trout is primarily found in the cold headwaters of the Athabasca drainage in Alberta, Canada. [1] [2] The Athabasca rainbow trout is one of the few native rainbow trout populations found in an Arctic Ocean watershed. [3] The Athabasca River is a tributary of the Mackenzie River system which flows north into the Arctic ...
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 ...
Natural reproduction of fish species, especially eastern brook trout, has led to overpopulation and “stunting” from starvation in low nutrient environments. The result has been decreased interest from fishermen, while causing large, negative impacts on natural lake biota. [ 2 ]
"Rainbow trout love cold water and can be caught on a variety of baits and lures (worms, commercially available pastes, corn, spinners, spoons, flies and more), and are great to take home and eat.
The Kamchatkan rainbow trout ("mikizha") comprises various ecological forms, including anadromous and resident freshwater forms and their intermediates. [6] [7] Russian taxonomy has long attributed the rainbow trout to the genus Parasalmo, and has further considered the Kamchatkan rainbow trout as composed of two distinct species, Parasalmo mykiss and Parasalmo penshinensis, whose ranges overlap.
