I've actually now tried the Ark. Game & Fish suggestion about soaking questionable fish in a solution of 1 gallon of water, 2 tablespoons of salt, and 1 teaspoon of baking soda. I did add 2 tablespoons of lemon juice one time and 2 tablespoons of vinegar another time as per suggestions on this thread. It really worked well, and I know this fish was fishy tasting because I didn't do anything to the first bag I cooked, and it was strong. The next 2 "treated" bags were really mild and good.
