Home canning or jarring is an excellent way to extend the shelf life of your fish. Your fish can be canned fresh, or it can be frozen and canned as it reaches its expiration date. You can also smoke the fish first and then preserve in jars. Canned salmon is great for making dips, salmon cakes, or adding to your favorite pasta or rice recipes.
