Sturgeon: Conservation Welfare in Aquaculture 2025
Overview: Updated 2025 welfare assessment for sturgeon in conservation aquaculture and caviar production.
Key Welfare Facts
All 27 sturgeon species are threatened with extinction, making aquaculture's conservation role critically important.
Non-lethal caviar stripping allows females to survive and produce multiple caviar harvests over many years.
Adoption of non-lethal methods has increased significantly among premium producers in Italy, Germany, and France.
Long-term welfare of sturgeons kept for repeat harvesting requires large tank volumes and excellent water quality.
Wild sturgeon caught for aquaculture seeding experience capture, transport, and adaptation welfare challenges.
Captive breeding programmes contribute directly to conservation of critically endangered species alongside production.
Welfare Assessment
Sturgeon welfare and conservation are deeply linked; supporting non-lethal caviar production and conservation breeding programmes simultaneously improves animal welfare and helps save species from extinction.
What You Can Do
Choose caviar from certified non-lethal production operations where available
Support aquaculture operations participating in sturgeon conservation breeding programmes
Advocate for international agreements protecting wild sturgeon and their river habitats
