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.
An Atlantic sturgeon at the Aquarium du Québec. Rather than having true scales, the Atlantic sturgeon has five rows of bony plates known as scutes.Specimens weighing over 800 lb and nearly 15 ft in length have been recorded, but they typically grow to be 6–8 ft (1.8–2.4 m) and no more than 300 lb (140 kg).
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.
If baby Atlantic Sturgeon are actually discovered in the river, that would be the sign marine scientists need to prove that that type of fish is making a comeback.
Acipenser is a genus of sturgeons.With 17 living species (others are only known from fossil remains), it is the largest genus in the order Acipenseriformes.The genus is paraphyletic, containing all sturgeons that do not belong to Huso, Scaphirhynchus, or Pseudoscaphirhynchus, with many species more closely related to the other three genera than they are to other species of Acipenser.
White sturgeon are the largest freshwater fish in North America. They look prehistoric, with bony, dinosaur-esque scales called scutes, and they get huge — some grow longer than 10 feet, and ...
Since 1996 Baltic sturgeon recovery has been attempted, with American donor populations used due to genetic similarities. Re-introduction with focus on returning these sturgeon to their native spawning grounds. [17] NatureServe considers the species Vulnerable. [18] In 2012, the Atlantic sturgeon received protection under the Endangered Species ...
