Rainbow trout is popular in Western cuisine; both wild-caught and farmed fish are eaten. It has tender flesh and a mild, somewhat nutty flavor. Wild fish has a stronger, gamier taste than farmed fish. While the taste of wild-caught trout is often promoted as superior, rainbow trout and "steelhead" sold in American restaurants is farmed. Farmed rainbow are considered one of the safest fish to eat and are noted for high levels of vitamin B and a generally appealing flavor. Seafood Watch ranks farmed rainbow as a "Best Choice" fish for human consumption. In Montana, it is illegal to sell or market wild-caught rainbow trout, which are legally classified as game fish.
