Steelhead trout, aka rainbow trout, is very similar in color, taste, and texture to salmon. However, most of the trout available in U.S. markets is farm raised, which makes it a more sustainable and cheaper option. Though wild steelhead trout populations have declined due to human and natural causes, management of the U.S. trout aquaculture industry is deemed effective and well regulated. Trout has a robust flavor and can be used in any recipe that calls for salmon.
