Introduction to Rainbow trout, steelhead

Trout farming is North America’s oldest aquaculture business, going all the way back to the 1880s with the establishment of the first trout hatchery. Idaho now produces 70% of the rainbow trout farmed in the United States. Domestically, all rainbow trout are farmed, either in concrete raceways or earthen ponds. Salmo gairdneri was renamed Oncorhynchus mykiss in 1989. Thus, while doing research in older technical and culinary literature, S. gairdneri is the proper term to use. The rainbow trout, on the other hand, is still a member of the salmon family. Its sides, back, and fins are silver with black markings. The name rainbow may be deceptive, since the skin is really pinkish lavender in color. Steelhead trout are a saltwater variant of rainbow trout. Generally, rainbows relate to freshwater fish. Rainbows grown on farms mature to market size of 8 to 10 ounces in eight to twelve months.
