Sturgeon farming for caviar raises significant welfare questions given the long production cycles, egg extraction methods, and the documented sentience of these ancient fish.
Sturgeon welfare in aquaculture involves the paradox of very long production periods requiring sustained welfare management for individual animals held for years or decades. The traditional kill-based extraction of roe causes significant welfare harm to individuals that may have been under human care for 10-15 years. Humane alternatives using ultrasound-guided biopsy or C-section approaches that allow animals to survive and produce multiple times represent welfare improvements that also benefit producers through repeat production. Long production periods mean cumulative welfare across a sturgeon lifetime, making housing conditions, water quality, and management stress major considerations.
