Caspian Sea Wildlife Welfare 2025

The Caspian Sea — the world's largest landlocked body of water — is a unique ecosystem supporting endemic seals, critically endangered sturgeon, and significant waterbird populations. Oil development, overfishing, and rapid water level changes create profound welfare challenges.

Caspian Seal Welfare Crisis

Dramatic Decline: The Caspian seal — found only in the Caspian Sea — has declined from over 1 million individuals to approximately 100,000 today. Annual breeding colony monitoring shows continuing decline. Key welfare threats: industrial pollution (organochlorine and heavy metal bioaccumulation causing reproductive failure and immune suppression); mass mortality events from distemper-like virus; hunting for pups and oil (several thousand killed annually in Kazakhstan); and oil spills contaminating fur and causing hypothermia. The 2000 mass mortality event killed an estimated 10,000-12,000 seals — a welfare catastrophe whose causes remain partially unclear.

Sturgeon Poaching Welfare

Caspian beluga caviar was the world's most valuable food product — driving beluga sturgeon to Critical Endangerment. Despite international trade bans (CITES Appendix I), poaching continues through black markets. Gill net poaching kills adult sturgeon that may be 80+ years old and irreplaceable. Electrofishing (used by poachers) causes acoustic trauma before killing. Conservation aquaculture at Russian and Azerbaijani hatcheries releases millions of juvenile sturgeon annually — providing welfare-positive life restoration to a critically depleted population.

Sea Level Changes

The Caspian Sea level is falling dramatically — losing approximately 1m/year currently — due to climate change reducing inflows and increasing evaporation. This desiccates shallow coastal areas that are critical for seal pupping and waterbird breeding. Seal pups born on drying beaches face stranding risk; nesting waterbirds lose colonies when islands merge with mainland and become accessible to predators.
