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.
The biggest mistake of the Germans was that they did not expect to meet with such a rebuff of the Russians: true heroism, self-sacrifice, and hard work. The USSR proved its ability to mobilize its human resources, industry, and agriculture even under the terrible conditions of the first months of the war, when almost half the industrial and agricultural capacities were lost. The main achievement of
the USSR was evacuation and implementation of industrial plants, construction of new factories and enterprises, and development of new lands. The conversion of the economy to the war regime played a great role as well. The industry of the country was aimed at defense technology production, such as weapons, artillery, ammunition, tanks, fighters, and attack planes.
