The story
A female beluga may carry caviar worth more than her weight in silver, a price that fuelled rampant poaching after the Soviet collapse. Wild breeding females in the Caspian are now vanishingly rare; Danube protection, caviar trade bans and restocking are the species' remaining lifelines.
What's killing them
- Caviar poaching
- Dams blocking 90% of spawning habitat
- Decades to reach breeding age
- Pollution
