The rainbow trout (Oncorhynchus mykiss) is a species of the salmon
family native to cold-water tributaries of the Pacific Ocean in Asia and
North America. Those that spend their lives in streams and rivers
average between 1 and 5 lb (0.5 and 2.3 kg); others, called steelhead
trout, live in the ocean or the Great Lakes for two to three years
before returning to fresh water to spawn, and may reach 20 lb
(9.1 kg). Coloration varies widely, but all adult fish are
distinguished by a broad reddish stripe along the lateral line, from
gills to the tail, which is most vivid in breeding males. Wild-caught
and hatchery-reared forms of this species have been transplanted and
introduced for food or sport in at least 45 countries. Introductions to
locations in the U.S., Southern Europe, Australia and South America
outside the fish's native range have damaged native fish species when
the trout has preyed on them, out-competed them, transmitted contagious
diseases, or hybridized with closely related species. Some local
populations of specific subspecies, or in the case of steelhead,
distinct population segments, are listed as either threatened or
endangered under the Endangered Species Act. The steelhead is the
official state fish of Washington.
