Frozen raw fish shelf life, answered
How long does frozen raw fish last in the fridge?
3–4 days at 4°C (40°F) or colder. Keep it sealed so it does not pick up moisture or odours.
How long does frozen raw fish last in the freezer?
6 months for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does frozen raw fish last at room temperature?
It is not meant to be kept at room temperature. Refrigerate it.
How long is frozen raw fish good for past the expiration date?
Frozen raw fish past its best-by date is usually safe if stored well; check smell, look and taste before using.
How can you tell if frozen raw fish is bad?
Dry, greyish-white patches. Safe, but trim them off. Heavy ice inside the pack means it has thawed and refrozen. Off smell after thawing — discard.

How to thaw frozen raw fish
In the fridge
Move it to the fridge the night before; texture holds best.
At room temperature
Only for shelf-stable foods; perishable food should not thaw on the counter.
From frozen
Many foods go straight into soups, sauces, smoothies or the oven.
Frozen raw fish left out overnight
Frozen raw fish is not a high-risk food, but a night out shortens its fridge life. Refrigerate it and use soon.
