How Long Does Sturgeon Last in the Fridge?
Safety and Freshness Guide for Raw Sturgeon
Raw sturgeon lasts 1–2 days in the refrigerator.
Sturgeon is a premium seafood prized for its firm texture and rich, buttery flavor. Because it is a highly perishable raw fish, maintaining a strict cold chain is essential to prevent rapid bacterial growth. To ensure food safety and optimal culinary quality, sturgeon should be kept in a refrigerator set to 40°F (4°C) or below and consumed within a very short window. For the best eating experience, plan to cook your sturgeon within one to two days of purchase. If you do not intend to prepare it immediately, freezing is the most effective way to preserve its delicate fats and proteins for future use.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
