What is the scientific name for the sturgeon yielding Kaluga caviar?

Answer

Huso dauricus

The source of pure Kaluga caviar is the Huso dauricus sturgeon. While this species itself is critically endangered and highly regulated, the Kaluga product widely accessible in the modern market is frequently a hybrid. This farming strategy often involves crossing *Huso dauricus* with other species, such as *Acipenser Schrenckii* or even *Huso huso*, to create the Kaluga Hybrid. The focus on controlled, sustainable aquaculture, particularly originating from regions like China, has allowed farm-raised Kaluga to become a staple in high-end dining services.
