Recorded distribution in Britain and Ireland
Little is known about the current distribution of the Atlantic sturgeon, following over-fishing, although it may still be found in rivers and inshore waters from Scotland down to the eastern and south-western British Isles and the Irish Sea.
Global distributionOnce widely distributed in the North East Atlantic, Baltic Sea, and the Mediterranean coast of Europe and the Black Sea.
Acipenser sturio is a demersal species. It can tolerate a wide range of salinities. Most of its life is spent at sea, relatively close to the coast, but it enters rivers to spawn.
- Bottom-dwelling fish with an olive-brown upper body and a white belly.
- Maximum length of up to 3.5 m and a maximum weight of over 300 kg.
- Five lateral rows of bony platelets.
- Conspicuous barbels are visible under the lower jaw, halfway between snout and mouth
Additional informationAcipenser sturio is a long-lived (up to 100 years) and slow-growing species. This has left it vulnerable to fishing pressure and is now severely threatened by commercial fishermen targeting, in particular, the caviar contained within the females (Elvira, 2000). It was once widely distributed in the North East Atlantic, Baltic Sea, and the Mediterranean coast of Europe and the Black Sea. The last remaining breeding population (in the Garonne in France) is in decline. Hence, it is listed as Critically Endangered by the IUCN (Rosenthal et al., 2007; Gesner et al., 2010).
