Sturgeon farming for caviar production involves the keeping of large, long-lived fish in captive conditions that present specific welfare challenges.
Sturgeon aquaculture welfare encompasses multiple unusual welfare considerations: these are extremely long-lived fish whose production cycles span years to decades, meaning cumulative welfare impacts of poor conditions are very significant. The development of non-lethal caviar extraction — surgically removing eggs without killing the female — represents a welfare improvement over traditional methods but the surgery itself is a welfare event requiring appropriate analgesia. The conservation case for sturgeon farming is strong — reducing wild harvest pressure on critically endangered species — but must be matched by welfare investment commensurate with the cognitive and physiological complexity of these large, long-lived fish. Developing sturgeon-specific welfare standards requires dedicated research investment.
