1fillet(about 3 ounces cooked) of your favorite fish (I used salmon - haddock, founder, sea bass, cod, snapper, tilapia, etc. will also work well)
Seasoning, as desired
Place each serving of salmon (or your fish of choice) on a sheet of aluminum foil. Season it as you like. Wrap the salmon in the foil, creating a packet.
Layer the packets of fish in your slow cooker.
Cover and cook on HIGH for 1.75 to 2.0 hours, or LOW for 3 to 4 hours. Check it at the earlier time to avoid overcooking. Your fish is done when it flakes easily with a fork. The packets on the bottom with cook at the same rate as the packets on top.
