About 80% of the world population of sturgeons inhabit in the Caspian Sea. Beluga, Russian sturgeon, sterlet and starred sturgeon are endemic to the Caspian basin. Sturgeons have been living on the planet for over five million years. This fish has outlived mammoths and dinosaurs and now humans threaten to exterminate it. Sturgeons are long-livers; beluga can live up to 150 years but now it is under the threat of extinction. Although it has no dangerous enemies in nature, poaching causes its uncontrolled extermination. There are several fish farms in the Astrakhan Region which breed
surgeons. 'BIOS' KaspNIRKh is one of the largest farms which combines research and industrial activities. It is a big maternity hospital for fish. They breed the sturgeons from spawn and treat each of them with love and care. 'BIOS' had received and executed the following government order: to breed 560 thousand pieces of sturgeons and release them into the Volga River and the Caspian Sea. So, there is hope that 10-20 year later when the fish which has been released, will come back to the Volga for spawning, thus saving the population.
