hatchery steelhead pose ecological risks to wild steelhead populations. Hatchery steelhead are typically larger than the wild forms and can displace wild-form juveniles from optimal habitats. The dominance of hatchery steelhead for optimal microhabitats within streams may reduce wild steelhead survival as a result of reduced foraging opportunities and increased rates of predation. Uses Fishing Rainbow trout and steelhead are highly regarded game fish among anglers. Rainbow trout are a popular target for fly fishers, and several lure fishing methods are used. The use of lures presented via spinning, casting, or trolling techniques is common. Rainbow trout can also be caught on various live and dead natural baits. Many anglers consider the rainbow trout the hardest-fighting trout species, as this fish is known for leaping when hooked and putting up a powerful struggle. It is considered one of the top five sport fish in North America, and the most important game fish west of the Rocky Mountains. The International Game Fish Association recognizes the world record for rainbow trout as a fish caught on Saskatchewan's Lake Diefenbaker by Sean Konrad on September 5, 2009, which weighed and was a genetically modified hatchery escapee. There are tribal commercial fisheries for steelhead in Puget Sound, the Washington coast, and in the Columbia River, but there has been controversy regarding overharvesting of native stocks. The highly desirable sporting qualities and adaptability of the rainbow trout to hatchery rearing and new habitats resulted in it being introduced to many countries around the world by or at the behest of sport fishermen. Many of these introductions have resulted in environmental and ecological problems, as the introduced rainbow trout disrupt local ecosystems and outcompete or prey upon indigenous fishes. Other introductions to support sport angling in waters either devoid of fish or with seriously depleted native stocks have created world-class fisheries such as in the Firehole River in Yellowstone National Park and in the Great Lakes. As food 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 typically farmed. Farmed rainbow trout are considered one of the safest fish to eat and are noted for high levels of vitamin B and
