Can You Vacuum Seal Fish? The Best Way to Preserve Fish for Longer Storage.
Yes, fish can be vacuum-sealed to prolong its shelf life and retain freshness. Vacuum sealing removes all the air inside the packaging, preventing the growth of bacteria, fungi and other harmful microorganisms that can spoil the fish. It also prevents the fish from freezer burn, dehydration and oxidation. Vacuum-sealed fish can last for several months when stored in a freezer or refrigerator.
