What is a Russian sturgeon?

Russian sturgeon is a fish of the family Acipeseridae under the genus Acipensser. It is the scientific name is Acipensser Gueldenstaedtii. In the past, it was a valuable fish for both its size and its caviar. Today the fish is critically endangered. The geographical range of fish included the Caspian, Black and Azov Sea. Today it is located only in the Caspian Sea and the surrounding areas. It is originally from the countries of Azerbaijan, Bulgaria, Georgia, Iran, Kazakhstan, Moldova, Romania, Russia, Serbia, Turkey, Turkmenin and Ukraine. Previously, the fish was found in Austria, Croatia and Hungary, but now it is extinct in these places. It is black white color, while the body is black, while the dorsal fin and abdomen are white. They usually feed on smaller fish, molluscs and crustaceans. The shallow -living fish, rarely drops below 98 feet (30 meters) to depth. This is usually seen separately, groups of fish are usually seen only during friction, which is in May and June. Fish are very slow adolescents and can live for almost 50 years. Thanks to this slow ZRALocals are particularly vulnerable over excessive fishing.

In the past, Russin Sturgeon was valuable fish, commercially and for sport. The massive size of the fish has made him a popular game goal, while his caviar made him a valuable commodity for commercial fishermen. Since 1996, fish have been categorized as an endangered International Union for Nature Conservation (IUCN). Currently, fish are categorized as "critically endangered", which is one step above the classification as extinct in the wild.

The effort to reduce the fishing of the Russian Jeleen was not quite successful. Although in many laws that restrict or completely limit fishing of the animal, local fishermen are commonly ignored by local fishermen. Fishing is not the only reason to decline in a massive decline in fish population. The main contributor to its declining level is the construction of the dam. The dams built around the Caspian Basin have eliminated more than 70 precaution since the 1950sFish friction fish, which made it difficult for fish to breed. Pollution of oil from oil and industrial waste also kills fish in bulk numbers. It is estimated that tens of thousands of Russian Sturegon, not more, were killed as a direct result of water pollution.

Efforts to reproduce the Russian sturgeon in captivity and relaxation of life fish into nature were made, but were not very successful. At the age of 90, millions of screeds were released into the Volga and Azov River in an effort to restore the population of the Russian sturgeon, nor were very successful. According to IUCN, only one Natpopulation of the fish Urals still exists in the wild and has overwhelmed them strongly.
