How Long Can You Keep Frozen Fish?

Freezer storage has two separate questions: how long the fish remains safe under continuous frozen storage, and how long it retains its best flavor and texture. Start with the instructions on the package and the condition of the fish when it was frozen.

Storage Times Are Quality Guidelines

FoodSafety.gov says food held continuously at 0°F (-18°C) or below can remain frozen indefinitely; its freezer time recommendations concern quality. Freezing does not make spoiled fish safe.

Fish group Suggested freezer time for quality
Fatty fish, including salmon and tuna 2–3 months
Cod, halibut, sole, and similar lean fish 6–8 months
Pollock, ocean perch, rockfish, and sea trout 4–8 months

These are household guidelines from the FoodSafety.gov Cold Food Storage Chart, not a replacement for a product-specific label or best-quality date. Commercial packaging and storage history vary; do not automatically add another year to the date you receive an order.

Protect Flavor and Texture

  • Keep the freezer at 0°F or below and check it with a thermometer.
  • Keep packaging intact and protect fish from exposure to air.
  • Label portions with the species and freezing date.
  • Use older packs first and thaw only the amount needed.

Freezer burn affects quality. It is different from spoilage caused by improper handling. Appearance or smell cannot establish that a mishandled product is safe.

Thawing Frozen Fish

Thaw in the refrigerator and follow package instructions, including directions to open or remove vacuum packaging. Do not thaw fish on the counter. If using a faster thawing method, follow the package and FDA instructions and cook promptly.

For cooked fish, check the thickest part with a thermometer; the FDA recommendation is 145°F. See FDA guidance for fresh and frozen seafood.

Frequently Asked Questions

Does vacuum packaging guarantee 12 months of quality?

No single time applies to every product. Follow the product label and account for its storage history.

Does freezing make fish suitable for sushi?

Ordinary home freezing is not proof that fish is suitable for raw consumption. Follow the supplier’s intended-use instructions.

Can frozen fish go in the refrigerator?

The refrigerator is for thawing and short-term storage, not long-term frozen storage. Follow the package directions and prepare thawed fish promptly.
