Native in southeastern Oregon and parts of California and Nevada on the periphery of the Great Basin. In general, lake- and sea-run fish grow larger than their river-dwelling counterparts, but some tailwaters also grow especially large specimens. I have been know to be wrong from time to time. But surgens from what I been told by numerous of people is 1 inch per year. Other significant trout-producing countries include the U.S., Iran, the United Kingdom,[51] and Lesotho. [45][46][47][48] Six of ten Canadian provinces have rainbow trout farms, with Ontario leading production. [60] A typical TU project is the Circle Creek Fish Passage Project, in which access to a spawning stream is being improved for steelhead and other salmonid species. Rainbow trout are a popular target for fly fishers, and several angling methods are used. In Chile and Norway, sea cage production of steelhead has expanded to supply export markets. [78] Some of the salmonids that M. cerebralis infects (bull trout, cutthroat trout, and anadromous forms of rainbow trout—steelhead) are already threatened or endangered, and the parasite could worsen their population decline. Among the 492 trout that were planted with radio transmitters, 246 were rainbow trout and 246 were Apache. By the 9 month mark, you can expect each fish to weigh at least a … LOL Where M. cerebralis has become well-established, it has caused decline or even elimination of whole cohorts of fish. The disease is characterized by subcutaneous hemorrhaging of the mouth, fins, and eyes. [77] Whirling disease threatens recreational fishing, which is important for the tourism industry, a key component of the economies of some U.S. western states. Anadromous forms are known as steelhead, freshwater forms as rainbow trout. [98], Releases of conventionally reared hatchery steelhead pose ecological risks to wild steelhead populations. As rainbow trout grow, the proportion of fish consumed increases in most populations. Eggs from the McCloud hatchery were also provided to the San Leandro hatchery, thus making the origin and genetic history of hatchery-bred rainbow trout somewhat diverse and complex. Adult freshwater forms are generally blue-green or olive green with heavy black spotting over the length of the body. Lake-dwelling and anadromous forms are usually more silvery in color with the reddish stripe almost completely gone. They are native to the alluvial or freestone streams that are typical tributaries of the Pacific basin, but introduced rainbow trout have established wild, self-sustaining populations in other river types such as bedrock and spring creeks. [112], The color and flavor of the flesh depends on the diet and freshness of the trout. well depending on tank. Dominance of hatchery steelhead for optimal microhabitats within streams may reduce wild steelhead survival as a result of reduced foraging opportunity and increased rates of predation.
