Proper storage keeps sea fish fresh, safe and full of flavor. Fish is more perishable than most foods, so the way you store it in the first few hours makes a big difference. Whether you plan to cook tonight or next month, these simple steps will protect your catch.
Get It Home Safely
Bring fish home as quickly as possible, ideally in a cool bag with ice packs. Fish left at room temperature for more than two hours, or one hour in hot weather, should be discarded. Make the fish shop your last stop when you go shopping.
Storing Fish in the Fridge
Set your fridge to 4 degrees Celsius or below, and keep fish on the lowest shelf, where it is coldest and cannot drip onto other foods. Fresh fish keeps for one to two days, so plan to cook it soon.
Step-by-Step Fridge Storage
- Rinse whole fish gently under cold water, then pat dry with paper towels.
- Remove the guts and gills from whole fish, since these spoil first.
- Wrap the fish tightly in cling film or place it in an airtight container.
- Set the container on a tray of crushed ice, then store it on the bottom shelf. Replace melted ice regularly.
Cooked fish should be cooled within two hours and eaten within two days.
Storing Fish in the Freezer
Freezing is the best way to keep sea fish for longer. At minus 18 degrees Celsius or below, fish stays safe indefinitely, but quality is best within a set time:
- Oily fish such as salmon, mackerel and sardines: two to three months
- Lean white fish such as cod, haddock and sea bass: up to six months
- Cooked fish dishes: about three months
How to Freeze Fish Properly
Freeze fish as fresh as possible, never when it is close to spoiling. Pat it dry, then wrap each portion tightly in cling film or foil to remove as much air as you can. Place the wrapped portions in a freezer bag, press out the air and seal. Label with the species and date. Freeze in single-meal portions so you only thaw what you need.
Prevent Freezer Burn
Freezer burn appears as dry, grayish patches and affects texture and taste. Avoid it by using airtight packaging, keeping the freezer full and steady in temperature and avoiding repeated opening. A thin glaze of ice around the fish, made by dipping it in cold water and freezing, also protects it.
Smart Storage Tips
- Keep raw fish away from cooked foods and ready-to-eat items.
- Use a separate container to prevent odors spreading to other foods.
- Never refreeze fish that has fully thawed unless you cook it first.
- Rotate stock, using older packages first.
Signs Fish Has Gone Bad
Throw fish away if it has a sour or ammonia smell, slimy surface, dull color or soft flesh that does not spring back. When in doubt, throw it out.
Final Thoughts
Good storage is simple: keep fish cold, wrapped tightly and away from other foods. Cook fresh fish within a day or two and freeze the rest properly, and you will enjoy safe, delicious sea fish whenever you want it.
