Rainbow trout, native to the United States, are raised in concrete troughs wherever an abundant source of clean water is available. The flesh is mild, delicate, and sweet. Steelhead trout has pink flesh and a mild trout taste. Most rainbow and steelhead available on the market is farm-raised. Arctic char, another trout family fish, either dwells in lakes or lives in salt water, but spawns in fresh water. Whether wild-caught or farm raised, its flesh varies from pink to red, depending on the size. Wild-caught lake trout (also called togue or grey trout) has a higher oil content than other trout and its flesh may be white or pink.

Trout is nearly always sold whole and gutted. Boneless trout is also available.
