Frozen salmon can be cooked. Any icy glaze should be removed first by running tap water over the fish, and the fish should then be patted dry. It can be rubbed with olive or vegetable oil.
Whole salmon can be cooked many different ways from frozen; it just takes a little longer than fresh according to CookitFrozen.com. If the salmon was frozen soon after being caught, it may be even better than the fresh salmon found at most supermarkets.
To make canned salmon, soak the fillets in brine, smoke the fish, place the fish in clean, lidded canning jars, and simmer the filled jars for 100 minutes in a pressure cooker at 11 PSI. Use the pressure cooker according to the instructions in the owner's manual.
Even if salmon is frozen or smoked, it eventually goes bad. Various preservation methods give it a variety of shelf lives, but the printed date on the package gives an idea as to when salmon needs to go into the trash.
Cooked salmon can be frozen for 2 to 3 months at 0 degrees Fahrenheit for best quality. Allow cooked salmon to cool completely before placing it in an airtight, freezer-safe bag or container. It can also be wrapped tightly in freezer wrap or aluminum foil.
Dogs can eat salmon as long as it is cooked properly. Consumption of raw salmon can result in salmon poisoning if the salmon is infected with certain parasites.
Although frozen fish can stay safe indefinitely, it begins to degrade in quality after three to six months. This storage time depends on the quality of the fish and how well it was packaged.
