Historical study of sturgeon fishes before and after the Islamic Revolution of Iran

Caspian Sea, the largest lake in the world, has been geographically and historically position in a privileged position for a long time. Sturgeons are considered to be the most valuable creatures of the Caspian Sea, and the Caspian Sea caviar has long been of worldwide interest. In this study, sturgeon management strategies were considered before and after the Islamic Revolution of Iran. The results showed that before the glorious victory of the Islamic Revolution, there was no management and control over the Caspian Sea, and decisions were made by the Soviet Union, and after the collapse of the Soviet Union and its division into various republics, there were many administrative misunderstandings in this area. This development has led to the emergence of new issues, such as the dramatic decrease in sturgeon species. In the meantime, only the Islamic Republic of Iran has implemented its ethical-environmental mission and improved the rehabilitation of these valuable fish stocks. Investigation of sturgeon catch statistics shows that in recent years, only Persian sturgeon condition has been better than other species, and four other species have experienced a significant reduction. After the glorious victory of the Islamic Revolution, significant activities have been undertaken in this area, including: the restoration of reserves and the release of fish larvae to the sea, the sturgeon culture in unconventional inland waters and in cages, increase of research centers and universities with the management approach of sturgeons stocks and introduce of valuable species of Persian sturgeon.
