Scientific name: Acipenser nudiventris
The species was never abundant in the Danube River basin. In 2009, the last Ship Sturgeon was caught in Hungary, in the Middle Danube. Ship Sturgeons are listed as extinct in Romania and Bulgaria.
The Ship Sturgeon likes to live at sea, close to shores, in freshwater, deep stretches of large rivers.
They spend at least part of its life in salt water, returning to rivers to breed.
They inhabited the Black, Azov, Caspian and Aral Seas, from where the spawners migrated upstream the rivers for spawning.
The Ship Sturgeon is a rather large species and can reach lengths of more than 2 meters. A maximum age of 36 years was recorded in the Kura River (Caspian Sea Basin). It takes males and females up to 9 and 14 years, respectively, to mature. The females carry 200,000 to 1,300,000 eggs, depending on their size.
