| Popis: |
Following a sharp reduction of sturgeon stocks up to 50-fold in the Caspian and Azov Seas, as well as in another parts of this area, caviar production and the volume of its delivery to the world market has also reduced several-fold and supplies approximately 10% of the demand. In recent years, one of the most intensively developing trends in sturgeon breeding is aquaculture, where the total volume of caviar produced on sturgeon farms in the world has reached a level of more than 13–15t. |
