The European sea sturgeon (Acipenser sturio), also known as the Atlantic sturgeon or common sturgeon, is a species of sturgeon native to Europe. It was formerly abundant, being found in coastal habitats all over Europe. [5] Most specifically, they reach the Black and Baltic Sea. [6] It is anadromous and breeds in rivers.
The now nearly extinct sturgeon population in the Baltic Sea area belongs to the Atlantic sturgeon A. oxyrinchus rather than to the European species A. sturio as had been thought. A. oxyrinchus migrated to the Baltic about 1300 years ago and displaced the native A. sturio .
Sturgeon range from subtropical to subarctic waters in North America and Eurasia. In North America, they range along the Atlantic Coast from the Gulf of Mexico to Newfoundland, including the Great Lakes and the St. Lawrence, Missouri, and Mississippi Rivers, as well as along the West Coast in major rivers from California and Idaho to British ...
Atlantic sturgeon are born in freshwater and migrate to the sea. Sturgeon populations began to drop steeply more than 100 years ago amid pollution, dam construction and overfishing. The decline was driven in part by demand in the 1800s for caviar, a delicacy of salt-cured sturgeon eggs.
The European sea sturgeon (Acipenser sturio) The European sea sturgeon (Acipenser sturio), also known as the Atlantic sturgeon or common sturgeon, is now a Critically Endangered species (IUCN) status. [27] This species of sturgeon can reach a length of 6 m (20 ft), weigh up to 400 kg (880 lb) and reach an age of 100 years. [28]
Sturgeon are an anadromous species that live solitarily or in small groups. They migrate upriver in the spring to spawn. Sturgeons tend to inhabit the shallow waters of coastal shelves, coastal and estuarine areas on soft bottom in the sea, and can live down to a depth of 160 ft (49 m).
