When summarizing this report information it is necessary, unfortunately, to make a conclusion, that in reservoirs of Russia the majority of species, subspecies, populations and seasonal groups of sturgeon fish is in practice in a depressing condition, and many of them are under real threat of complete disappearance from local fish fauna. Especially tense situation has been notified in the Caspian and Azov Seas, where there were more than 90% of world stocks of these fishes. Some of the species, earlier most valuable for fisheries (e.g., the Azov great sturgeon, the Ob River sturgeon), has been already listed in the Red Data Book of Russia or require urgent listing.

The National Strategy on Conservation of Biodiversity and Sustainable Use of Sturgeons in Russia has been developed. The realization of this Strategy should be directed towards the following main tasks:

• Constant monitoring of Sturgeon populations status, numbers of their spawning part, and first of all of females, and development of biologically reasonable quotas for catching or its stoppage, depending on the data obtained;

• Rigid struggle with illegal catching of individuals of these species in places of feeding, hibernation and spawning;

• Complete stoppage of official catching in the seas or sites of feeding in the freshwater reservoirs to preserve stocks of immature individuals;

• Maintenance of natural reproduction, melioration of approach ways of adult fish and for sloping of young, protection of adult fish in spawning places and creation of strictly protected areas and reserves to reach these goals;

• Maintenance of appropriate level of sturgeon artificial breeding in compliance with scientific recommendations; simultaneous raise of its efficiency on the basis of increase of life hardiness of fingerlings and its release by a hatchery;

• Creation of live collections of female herds and development of cryo-conservation of sturgeon genes, their storage and use in the industrial scale.
