Due to the popularity of the Rainbow Trout, they have been stocked widely outside of their native range and can now be found across most of North America, and parts of Europe, South America, Asia, Africa, and Australia. Hatchery strain Rainbow Trout tend to be the greatest threat to many of these subspecies because they have the ability to interbreed with them and produce hybrids, but non-native Cutthroat, Brook Trout and Brown Trout have led to the decline of many native Rainbow and Redband Trout populations. Anadromous Redband and Rainbow Trout face the same threats as Pacific Salmon, but for non-anadromous Redband and Rainbow Trout populations tend to be more threatened by the introduction of non-native trout. However, genetics work indicates that the Chewaucan, Goose Lake and Warner Lakes Redband are most closely related to the Redband of the Sacramento Basin, while White River, Fort Rock, Catlow and Harney-Malheur are most closely related to Columbia Basin Redband. The Upper Klamath Lake Redband Trout identified as Oncorhynchus mykiss newberrii, but the classification of the other Northern Great Basin Redband trout is still a matter of debate. In the Northern Great Basins of Oregon, Nevada and California, there are eight unique populations of Redband Trout each native to a different internal basin Harney-Malheur, Fort Rock, Upper Klamath Lake, Klamath Headwaters, Chewaucan, Goose Lake, Warner Lakes, and Catlow Basins as well as the White River Redband in Northern Oregon. In many basins, there are no clear barriers to separate these subspecies and instead there appear to be transitional forms, which have made classification of Rainbow Trout problematic. Rainbow Trout are a diverse species and have a number of subspecies including Kamchatkan Rainbow Trout, Coastal Rainbow Trout, Columbia Basin Redband, Northern Great Basin Redband (there are several unique forms of these Redbands), McCloud River Redband, Eagle Lake Rainbow, California Golden Trout, Little Kern River Golden Trout, Kern River Rainbow Trout and Baja Rainbow Trout. Unlike Pacific Salmon, all Rainbow and Redband Trout are iteroparous meaning that have the ability to spawn more than once. The anadromous form of Rainbow and Redband Trout are commonly called Steelhead and has become a very popular game fish throughout the Pacific Northwest and other parts of the world where it has been introduced. Rainbow Trout like Pacific Salmon have the ability to migrate between fresh and salt water and home to their natal stream to spawn again. Rainbow Trout or Oncorhynchus mykiss is one of the Pacific Trout that is native to western North America and Northeastern Asia. Many populations have already gone extinct and the future of these fish Many efforts under way to conserve and maintain sustainable natural populations of Pacific salmon, but To a loss of fitness in the local environment.

3) Hydropower (dams), which block the upstream migration of adult salmon and may causeĭeath or injury to smolts during their downstream migration. 2) Habitat destruction from development, logging, alterations The major threats to Pacific salmon are summed up with the four H's: 1) Harvest from commercialĪnd recreational fishing.

behaviors, although there are exceptions to these traits for some species. Pacific salmon share several traits in common such as anadromy A migratory life history in which the fish are born in freshwater, migrate to the marine environment and return to freshwater to spawn., semelparity When a fish dies after a single spawning event, and homing Where migratory adults return to the same stream that they were born in. In North America, there are five species of native Pacific salmon: Chinook, coho, chum, sockeye and pink. Pacific SalmonĪll Pacific salmon belong to the genus Oncorhynchus, which also includes several species of Pacific trout. Species on this page click on the picture of the fish.
