A friend gave me a raw rainbow trout that she used for a photoshoot (you know, typical day in an art major's life) but I haven't fed it due to Nanophyetus salminicola/salmon poisoning concerns. I've read some people say that it's fine to feed rainbow trout and others that don't feed raw fish.
"Dogs and other canids — such as wolves, fox and coyotes — that eat RAW anadromous fish (fish that are born in fresh water and spend most of their life in the ocean, then return to fresh water swimming upstream to breed) are susceptible. Examples of anadromous fish are salmon, some species of trout, smelt, shad, striped bass and sturgeon."

If you feed raw fish, what type do you feed? I feed canned mackerel at times, but have yet to feed raw fish.
