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 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]
Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.
Globally, sturgeon fisheries are of great value, primarily as a source for caviar, but also for flesh. [42] Several species of sturgeon are harvested for their roe which is processed into caviar—a delicacy, and the reason why caviar-producing sturgeons are among the most valuable and endangered of all wildlife resources.

The liver may be pale, mottled with red hyperemic areas, the kidney may be swollen and unusually red, the spleen may be swollen, and the digestive tract may be empty. [ 21 ] External signs are not always present, but if they are, hemorrhaging on the skin's surface can appear as anywhere from tiny red dots (petechiae) to large red patches.
The fish most often implicated include barracuda, grouper, moray eel, amberjack, sea bass, and sturgeon. [2] Diagnosis is based on a person's symptoms together with having recently eaten fish. [1] If a number of those who eat the same fish develop symptoms the diagnosis becomes more likely. [1]
The disease is listed as a nonexotic disease of the EU and is therefore watched closely by the European Community Reference Laboratory for Fish Diseases. To keep track of the distribution of different IHNV genotypes, a database called Fishpathogens.eu [6] has been created to store data on different fish pathogens (including IHNV) and their ...
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.
