Core distribution of bull trout (Salvelinus confluentus) in U.S. 2005 [8]S. confluentus is found in the cold, clear waters of the high mountains and coastal rivers of northwestern North America, including Yukon, Alberta, British Columbia, Washington, Oregon, Idaho, and western Montana, as well as the Jarbidge River of northern Nevada and perhaps Alaska.
However, once they return to freshwater, they quickly take on the normal coloration of resident brown trout in preparation for spawning. Sea trout kelts (post spawn) return to their silvery stage as they migrate back to saltwater. [9] Adult brown trout are between 35 and 60 cm (14 and 24 in) long, and can weigh from 0.5 to 2.4 kg (1.1 to 5.3 lb).
As trout are predatory fish, lure fishing (which use replica baits called lures to imitate live prey) is the predominant form of sport fishing involving trout, although traditional bait fishing techniques using floats and/or sinkers (particularly with moving live baits such as baitfish, crayfish or aquatic insects) are also successful ...
In North America, five relatively well defined species are present, which, apart from the Arctic char, comprise the brook trout (S. fontinalis), bull trout (S. confluentus), Dolly Varden trout (S. malma) and lake trout (S. namaycush). This listing presents the taxa recognised in FishBase grouped by geography:
The Elwha is one of several rivers in the Pacific Northwest that hosts all five species of native Pacific salmon (chinook, coho, chum, sockeye, and pink salmon), plus four anadromous trout species (steelhead, coastal cutthroat trout, bull trout, and Dolly Varden char). From 1911 to 2014, dams blocked fish passage on the lower Elwha River.
The Dolly Varden trout (Salvelinus malma) is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America.Despite the name "trout" (which typically refers to freshwater species from the genera Salmo and Oncorhynchus), it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook ...

Arctic char is known to produce hybrids with its congeners, Salvelinus namaycush and Salvelinus fontinalis (brook trout). [30] The sparctic char is the intrageneric hybrid between Arctic char and brook trout. [30] Sparctic char grows faster than either parent species, are stronger and healthier, and are thus popular for sports fisheries. [30]
