Many of these introductions have resulted in environmental and ecological problems, as the introduced rainbow trout disrupt local ecosystems and outcompete or eat indigenous fishes. As rainbow trout grow, the proportion of fish consumed increases in most populations. as a visible guarantee, a reminder of this comforting promise. [55] As wild steelhead are in decline in some parts of their range, farmed rainbow are viewed as a preferred alternative. [31] There are genetic differences between freshwater and steelhead populations that may account for the smoltification in steelheads. + Dia dikelilingi cahaya yang terang-benderang, 28 seperti, tak masuk akal tentang kucing melompat- lompat dengan. [26], There are tribal commercial fisheries for steelhead in Puget Sound, the Washington coast and in the Columbia River, but there has been controversy regarding over-harvesting of native stocks. [9] Thus, in 1989, taxonomic authorities moved the rainbow, cutthroat, and other Pacific basin trout into the genus Oncorhynchus. Cookies help us deliver our services. In the east, Pennsylvania, North Carolina and West Virginia have farming operations. trout translate: 鱼, 鳟鱼, 鳟鱼肉, 人, 老家伙;(尤指)讨厌的婆娘,恶婆子. Another method is to use electrofishing which enable the fish to be caught alive and harvested or re-located. Nehring, R. B. [66] In the case of the westslope cutthroat trout (O. clarki lewisi), hybridization with introduced rainbow and Yellowstone cutthroat trout (O. clarki bouvieri) is threatening the westslope cutthroat trout with genomic extinction. For example, in 2005 anglers in Montana spent approximately $196,000,000 in activities directly related to trout fishing in the state. 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. Allow it to set in the refrigerator for at least 4 hours so that the cracker layer softens to a cake-like texture. In Texas hold 'em or Omaha hold 'em, a flop that contains three different suits. [117], Typical juvenile rainbow trout showing parr marks, Growth and oxidative stress on mitochondria. [18] Some coastal rainbow trout (O. m. irideus) and Columbia River redband trout (O. m. gairdneri) populations and cutbow hybrids may also display reddish or pink throat markings similar to cutthroat trout. This technique has been used in the Great Smokey Mountains National Park to rid it of rainbow trout that were introduced in the 1930s and have thrived ever since. [103] Other introductions to support sport angling in waters either devoid of fish or with seriously depleted native stocks have created world-class fisheries such as in the Firehole River in Yellowstone National Park,[104][105][106] and in the Great Lakes. [94] Steelhead in the Kamchatka Peninsula are threatened by over-harvest, particularly from poaching and potential development, and are listed in the Red Data Book of Russia that documents rare and endangered species. A female trout clears a redd in the gravel by turning on her side and beating her tail up and down. The practice began in the late 19th century,[50] and since the 1950s commercial production has grown dramatically. [54] California and Washington also produce significant numbers of farmed trout. [88] Even though it is native in North America, it is considered a nuisance organism or invasive species. Sikang is found in remote Local Malay Name: Ikan Malong, Ketingkor, Indung, Malung, Nong, Malong Kuning Local Hokkien: Mua Hu, Mua Kia Remarks: Pectoral fins well developed and … [53] In Chile and Norway, rainbow trout farmed in saltwater sea cages are sold labeled as steelhead. It eventually became established in natural waters of the Rocky Mountain states (Colorado, Wyoming, Utah, Montana, Idaho, New Mexico), where it is damaging several sport fishing rivers. [45][46][47][48] Six of ten Canadian provinces have rainbow trout farms, with Ontario leading production. A rainbow is often seen in the sky when the sun shines after it has rained. Translation API [50] In Montana, it is illegal to sell or market wild-caught rainbow trout,[110][111] which are legally classified as game fish. [64] In 1997, a group of approximately 40 ichthyologists, biologists and naturalists from several U.S. and Mexican institutions formed a collaborative group—Truchas Mexicanas—to study the diversity of Mexican native trout, most of which are considered subspecies of O. (often used with “of”) A wide assortment; a varied multitude. The eggs usually hatch in about four to seven weeks although the time of hatching varies greatly with region and habitat. [29], Like salmon, steelhead return to their original hatching grounds to spawn. As well as a freshwater race, there is also a migratory race - the Steelhead - which lives at sea and moves up-river to spawn. [67] Such introductions into the ranges of redband trout (O. m. gairdneri, newberrii, and stonei) have severely reduced the range of pure stocks of these subspecies, making them "species of concern" in their respective ranges.

[92][93], The Southern California DPS, which was listed as endangered in 2011, has been affected by habitat loss due to dams, confinement of streams in concrete channels, water pollution, groundwater pumping, urban heat island effects, and other byproducts of urbanization.

Astaxanthin is a powerful antioxidant that may be from a natural source or a synthetic trout feed. The parasite infects its hosts with its cells after piercing them with polar filaments ejected from nematocyst-like capsules. See more ideas about fish recipes, recipes, whole fish recipes. [97] Natural waterfalls and two major dams have isolated Russian River steelhead from freshwater rainbow trout forms above the impassable barriers; a 2007 genetic study of fin samples collected from steelhead at 20 different sites both above and below passage barriers in the watershed found that although 30 million hatchery trout were stocked in the river from 1911 to 1925, the steelhead remain of native and not hatchery origin.

"Cultured Aquatic Species Information Programme: "Trout farming in land-locked Lesotho is an export success", "Enteric Redmouth Disease of Salmonids LSC", "Weight, Length, and Growth in Cutbow Trout (, "Intercrosses and the U.S. These names faded once it was determined that Walbaum's description of type specimens was conspecific and therefore had precedence. [49], Rainbow trout are commercially farmed in many countries throughout the world. The disease is characterized by subcutaneous hemorrhaging of the mouth, fins, and eyes. Summer-run fish generally spawn in longer, more inland rivers such as the Columbia River. Where M. cerebralis has become well-established, it has caused decline or even elimination of whole cohorts of fish. Redmouth disease was first discovered in Idaho rainbow trout in the 1950s.[90]. In this juvenile stage, immature trout are often called "parr" because of the marks. [25] During spawning, the eggs fall into spaces between the gravel, and immediately the female begins digging at the upstream edge of the nest, covering the eggs with the displaced gravel. [95], Several studies have shown that almost all California coastal steelhead are of native origin, despite over a century of hatchery stocking. Trout Unlimited (TU) is a non-profit organization dedicated to the conservation of North American freshwater streams, rivers, and associated upland habitats for trout, salmon, other aquatic species and people.
