How to Store Raw Fish in Refrigerator

Fresh fish is one of the most perishable proteins you can buy — it deteriorates faster than meat or poultry. Proper refrigerator storage is essential to keep it safe and at peak quality. Here's how to store raw fish in the refrigerator correctly.

How Long Does Raw Fish Last in the Refrigerator?

This is the most important thing to know: raw fish should be cooked within 1–2 days of purchase. Unlike beef or pork, fish has very little margin for error. If you can't cook it within that window, freeze it immediately.

The Best Method: Store on Ice

The ideal way to store raw fish in the refrigerator is on ice — similar to how fish is displayed at a fish counter:

1. Fill a shallow container with ice — Use a rimmed baking dish or a ComSaf Airtight Container filled with crushed ice.
2. Place fish on top of the ice — Set the fish (still in its packaging or wrapped in plastic wrap) on the ice.
3. Cover loosely — Cover the container to prevent odor transfer.
4. Store on the bottom shelf — Always store raw fish on the lowest shelf to prevent drips from contaminating other foods.
5. Replace ice as it melts — Check daily and replenish ice as needed.

Standard Refrigerator Storage (Without Ice)

1. Keep fish in its original packaging or transfer to a SPLF Reusable Bag with air squeezed out.
2. Place on a plate to catch any drips.
3. Store on the bottom shelf.
4. Cook within 1–2 days.

How Long Does Raw Fish Last?

• Fresh fish fillets (refrigerator): 1–2 days
• Whole fresh fish (refrigerator): 1–2 days
• Smoked fish (refrigerator): 5–7 days (unopened package)
• Frozen fish fillets: 3–8 months
• Frozen whole fish: 6–12 months

How to Freeze Raw Fish

Freeze fish as soon as possible if not cooking within 2 days. Pat dry, wrap tightly in plastic wrap, then place in a FoodSaver Vacuum Sealer Bag for best results — vacuum sealing prevents freezer burn and preserves texture far better than regular bags. Alternatively, use a SPLF Reusable Freezer Bag. Label with the type of fish and date. Thaw in the refrigerator overnight.

Signs Raw Fish Has Gone Bad

• Strong, fishy, or ammonia-like smell (fresh fish smells mild and oceanic)
• Slimy or sticky texture
• Dull, opaque, or discolored flesh
• Flesh that doesn't spring back when pressed
• Past the use-by date

• ✅ Freeze immediately if not cooking within 2 days
• ✅ Use vacuum seal bags for best freezer quality
