The European Atlantic sturgeon (scientific name: Acipenser sturio) is a fish of the sturgeon family and genus. In the sturgeon order, the search characteristics of European Atlantic sturgeons are the same as those of Atlantic sturgeons, and species identification between the two can only rely on genetic identification. The largest European Atlantic sturgeon can grow up to 600 centimeters in length and weigh 1000 kilograms. The body height is 10.0-13.5% of the total length. The kiss is long and wide, with a kiss length of 52.6-65.8% of the head length. There are 9-16 dorsal bone plates, 24-40 lateral bone plates, 8-14 ventral bone plates, 30-50 dorsal fins, and 22-23 anal fins.

It is a large river sea migratory fish that can weigh up to 300 kilograms, age up to 60 years old, and typically measure between 4.3 and 5.3 meters in length. The kiss is long and wide, accounting for about 8% of its total length. The body is covered with 5 rows of bone plates, and the back color ranges from black to brownish gray, while the abdomen is white to gray. Young sturgeons usually inhabit freshwater bodies and gradually migrate towards the ocean as they grow. Food includes aquatic animals and plants, while adult sturgeons are omnivorous and feed on benthic organisms and small fish. The spawning behavior of Atlantic sturgeons is mainly influenced by water temperature, and they choose to lay eggs in flowing water bodies with hard objects such as rocks and pebbles.

The Atlantic sturgeon (scientific name: Acipenser oxyrinchus) is a fish species of the sturgeon family and genus. The Atlantic sturgeon can weigh up to 300 kilograms and is 60 years old. It is also common to find individuals 4.3-5.3 meters long. Young Atlantic sturgeons generally inhabit their "mother river" and then migrate to the ocean over time.. Young sturgeons mainly inhabit freshwater rivers and feed on aquatic animals and plants. Adult sturgeons are also omnivorous, but parent sturgeons stop feeding during their spawning migration. Postpartum adult sturgeons mainly feed on gastropods and other benthic organisms in freshwater. The Atlantic sturgeon is distributed along the east coast of the Atlantic Ocean in North America.
