Due to the worldwide decline of the sturgeon population, stocking programmes were developed for many of these species. The critically endangered anadromous sturgeon populations inhabiting the NW Black Sea and spawning in the Lower Danube River are no

During the last decades, the over-exploitation of sturgeon stocks for caviar production simultaneously with severe habitat deteriorations has led to drastic declines in the natural populations of the Danube River. As a result of (i) decrease of stur
