Raw salmon stays fresh in the refrigerator for one to two days. The fish can stay fresh in the freezer for two to three months.
Keep fresh salmon in its original packaging and unopened until it is ready to use. If the salmon is stored in the freezer, place it in the freezer before the refrigeration expiration date. When freezing salmon, wrap the fish in plastic wrap, freezer paper or aluminum foil in addition to the original packaging. Salmon is a significant source of protein, as one serving contains 39 grams. The fish is also high in vitamins B12 and C.
