Steelhead, popular in Western cuisine, has tender flesh and a mild, almost nutty flavor. However, farmed trout and those taken from certain lakes have an observedly earthy flavor which many people find unappealing; many shoppers therefore make it a point to ascertain the source of the fish before buying. Rainbow trout are raised in many countries throughout the world. Rainbow trout that are wild have a diet of scuds (freshwater shrimp), insects such as flies, and crayfish are the most appealing. Dark red/orange meat indicates that it is either an anadromous steelhead or a farmed Rainbow trout given a supplemental diet with a high astaxanthin content. The resulting pink flesh is marketed under monikers like Ruby Red or Carolina Red. Steelhead meat is pink like that of salmon, and is more flavorful than the light-colored meat of rainbow trout.
