What is Rainbow trout?
Rainbow trout ( Oncorhynchus mykiss ) are native to cold-water tributaries of the Pacific Ocean. They are considered to be native to Asia and North America, but have been introduced into many other environments, leading to extensive damage to native fishes. Rainbow trout are a popular food item. The flesh is tender and has a mild flavor. The color and flavor depend on the diet and freshness of the trout. Wild fish have a stronger flavor than farmed fish.
