Sturgeon are farmed primarily for caviar, one of the world's most expensive luxury foods. The welfare implications of keeping these long-lived, slow-maturing fish for years before harvest raise significant ethical questions.
Sturgeon farming welfare is complicated by the extreme time scales involved. An animal held for 10-15 years before caviar extraction has undergone a fundamentally different welfare experience than a salmon held for 18-24 months. Chronic stress indicators including reduced growth, abnormal behavior, and disease susceptibility reflect long-term environmental inadequacy. The development of non-lethal caviar extraction (stripping ripe eggs from anesthetized females) improves outcomes for females that can be returned to continue producing, reducing the number of animals needed for production. Welfare standards for sturgeon remain poorly developed compared to salmonids.
