Russian sturgeon

Russian sturgeon (Acipenser gueldenstaedtii) is one of the classic caviar sturgeons of the Caspian Sea basin, but in modern trade its commercial role is driven far more by aquaculture than by wild fisheries. Historically, its greenish to grey eggs, larger than those of other sturgeons, have defined the taste of traditional malossol Ossetra caviar, and today it remains one of the benchmark premium sturgeon species in the global farmed caviar market.

From a product perspective, Russian sturgeon is valued above all for caviar, while sturgeon meat remains an important co-product supporting the long production cycle of the farms. The meat is widely used in fine dining, gourmet smoking, and fillet production and distribution. Acipenser gueldenstaedtii is a slow-growing species, and the economics of farming depend on selling both premium roe and edible fish products rather than treating meat as an afterthought. In market terms, it occupies the upper tier of the category, with a strong identity in fine food, gastronomy, and specialty retail.

Commercially, Russian sturgeon belongs to a broader sturgeon industry now dominated by farmed production. Global sturgeon aquaculture is led by China, followed by Russia, Iran, Vietnam, and Italy, while within the EU the main caviar-producing countries are Italy, France, Poland, and Germany. Russian sturgeon itself remains an established species in Russian and European aquaculture, where it continues to hold a strong position as a premium caviar fish rather than a mass-market meat species.
