we had stocked steelhead(the rainbow/steelhead cross). they fight harder and seem to grow faster and the flavor is very close to salmon and they are all pink inside. I like them smoked but my favorite way to cook them and rainbow is to fillet and put on pan with skin sides down and sprinkle the meat side of fillets with POLISH SAUSAGE SEASONING. Yeah you heard right. them slow bake at 200 degrees in oven and I think it is the closest thing I can make to kippered salmon. I like them but then what do I know I like smoked carp as well. Good Eats if you are a foodie.
