This pro-tip is one I learned from the anglers in my life. 1.Skin and fillet the fish and place them in a single layer in a plastic zip-top freezer bag. 2. Fill the bag with fresh tap water so that the fish is covered. Squeeze out any air pockets and seal the bag. 3. Lay the bag flat on its side and freeze it in a single layer. Then you can stack or arrange the frozen fish like library books on a freezer shelf. The fish will keep with no freezer burn for up to 3 months. This WORKS!
