Sturgeon (White, Beluga, Atlantic, Siberian, Russian, Sevruga, Sterlet)

  • From:
    U.S.
    Method:
    Farmed- flowthrough, closed systems

Sturgeon aquaculture originated in Europe and North America more than a century ago in an attempt to supplement wild stocks. High demand for caviar, coupled with a long lifespan and late sexual maturation, has resulted in depletion or near-extinction for all 26 wild sturgeon species around the world. 

White sturgeon, a species native to the Western U.S., is the principal species used in aquaculture. These fish are raised in land-based tanks that operate either as flow-through or recirculating aquaculture systems. In flow-through systems, effluents are used for agriculture irrigation or are treated before entering natural water bodies. In recirculating systems, water is treated and reused as opposed to being discharged. As a high-value commodity, farmed sturgeon is tightly controlled therefore reducing the risk of escapes and disease outbreaks. There are moderate concerns associated with feed sources, however the overall impacts are shown to be low.
