Refrigerate cooked fish for 3 to 4 days at 40 °F (4 °C) or below. In the freezer it stays safe indefinitely, with best quality for about 4–6 months.
The 3–4 days is safety guidance; the 4–6 months is a quality target. Texture softens noticeably after freezing — plan frozen cooked fish for fish cakes, pasta, or chowder.

Can I freeze it?
Safe, with quality loss
Safe to freeze, but expect softer, drier texture. Best quality about 4–6 months.
Flaked fish holds up better than whole fillets. Sauced dishes (chowder base, fish pie filling) freeze better than plain cooked fish.
Prepare & portion. Cool promptly, flake or portion, and freeze in meal-sized amounts.
Package. Airtight containers or freezer bags with air pressed out.
Thaw & use. Thaw in the refrigerator and reheat gently to 165 °F (74 °C), or add frozen to soups and sauces.
Thawing and post-thaw handling
Thaw in the refrigerator (allow about 24 hours for small portions), in cold water in a leak-proof bag with water changes every 30 minutes, or in the microwave followed by immediate cooking. Never thaw on the counter. Reheat to 165 °F (74 °C).
Refreezing
Refrigerator-thawed cooked fish may be refrozen, with substantial further texture loss. The general rules are in the refreezing guide and the Refreezing Decision tool.
Common mistakes
Expecting a reheated fillet to match fresh texture — plan frozen cooked fish for mixed dishes.
Leaving cooked fish out through a long dinner, then refrigerating it anyway.
