The Atlantic sturgeon lifestyle

They feed on mollusks, worms, shrimps and other crustaceans, as well as fish such as sand lance. The Atlantic sturgeon finds its food by searching the loose bottom with his toothless belly mouth, helped by his barbells with taste buds and his snub nose.
The Atlantic sturgeon spawn at the foot of rapids and waterfalls in fresh water. It is an anadromous species, which then returns to salt water. The female produces an abundant egg laying, with between 800,000 and 2,400,000 eggs and can reach a maximum of 3,75 millions. The weight of her ovaries can reach one third of her total weight. After the spawning, the female travel back downstream.

The Atlantic Sturgeon habitat

The Atlantic Sturgeon lives on the funds where it feeds itself. The Atlantic sturgeon spend their adult lives in salt water, along the Atlantic coast, and in the estuary and Gulf of St. Lawrence.
