Stellate Sturgeon (Acipenser stellatus) was always rare in the Middle and Upper Danube, but also ascended several tributaries as Prut, Tisza, Drava, Sava and Morava. They migrate in spring and autumn. Males remain at spawning sites for up to six weeks, females for only 10-12 days. Stellate Sturgeons are listed as Critically Endangered.
Facts and Figures
- Stellate Sturgeons stop eating once they start their migration. After spawning, they return to the sea quickly where they begin feeding again.
- 87% decline in global commercial catch reflects the decline in species population.
- 55,000 sturgeons found dead in the Sea of Azov in 1990 as the result of pollution.
