How Long Does Sturgeon Last in the Fridge?
Safety tips and freshness cues for storing raw sturgeon.
Raw sturgeon lasts 1–2 days in the refrigerator.
Sturgeon is a prized fish known for its firm texture and rich flavor. Because it is a raw seafood item, maintaining a strict cold chain is essential to prevent bacterial growth. When stored correctly in a refrigerator set to 40°F (4°C) or below, sturgeon maintains its quality for a very short window. To ensure the best culinary experience and safety, it should be used within a day or two of purchase. If you aren't ready to cook it immediately, freezing is the preferred method to preserve the delicate fats and proteins.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long can I keep raw sturgeon in the refrigerator?
Raw sturgeon lasts 1–2 days in the refrigerator. Because it is a safety-critical food, it should be used as soon as possible after purchase.
How should I store sturgeon before cooking?
To maximize freshness, wrap the sturgeon tightly in plastic wrap or place it in an airtight container to keep it moist and protected from air contact.
Can I cook sturgeon if it smells slightly fishy?
Sage's Verdict: If the smell is 'oceanic,' it may be okay. However, if it has a strong odor of ammonia or sour milk, it has spoiled and you should toss it immediately.
Can I freeze sturgeon to extend its shelf life?
Yes, sturgeon can be frozen. While freezing preserves the meat, keep in mind that some texture changes may occur compared to fresh fish; however, it is an effective way to store it if you cannot use it within the 1-2 day window.
When it comes to large fish like sturgeon, when in doubt, throw it out! Safety is the best seasoning.
