Like other sturgeons, they eat polychaete worms and crustaceans which they find with their barbels. For example, 87 sturgeons were experimentally released in the Rhine near Nijmegen in 20. Conservation projects involving this species include reintroductions based on specimens from aquaculture with the first releases in 1995. Despite their estimated range of distribution, they have become so rare that they only breed in the Garonne river basin in France. They have been a protected species in Europe since 1982. Until the first decades of the twentieth century, these fish were locally abundant in Europe and were caught extensively for their caviar, but a sharp decline due to overfishing (which greatly accelerated from the second half of the nineteenth century onwards) led to their disappearance from the vast majority of their former ranger. The species can tolerate wide spread salinities and spend most of their lives in saltwater but migrate to spawn in freshwater. Like many other sturgeons, they spawn in the rivers inland from the coast. They are found on the coasts of Europe, except in the northernmost regions and the Baltic region, and have rarely even been known to cross the Atlantic Ocean to the coasts of North America. This sturgeon can reach 6 m (20 ft) and 400 kg (880 lb) in weight, but a more common length is 1.25 m (4 ft 1 in).They can reach an age of 100 years, and have a late sexual maturity (12 to 14 years for the males and 16 to 18 years for the females). The stomach is yellow and the back is a brownish grey. Five longitudinal lines of large osseous plates are found on the body of the fish. The dorsal fins are located very far back on the body. There are many sensitive barbels on the facial area. The wedge-shaped head of the European sea sturgeon ends in a long point. oxyrinchus, a species otherwise restricted to the Atlantic coast of North America. Although the name Baltic sturgeon sometimes has been used, it has now been established that sturgeon of the Baltic region are A. It is currently a critically endangered species. It was formerly abundant, being found in coastal habitats all over Europe. The European sea sturgeon ( Acipenser sturio), also known as the Atlantic sturgeon or common sturgeon, is a species of sturgeon native to Europe.
