• A medium to large anadromous fish found in the rivers that flow into the Caspian Sea, Black Sea, the western Pacific and the eastern Atlantic oceans. It has a firm white to pink flesh which may be baked, fried, grilled or smoked. They have armour-plated bodies and an elongated snout with a dark grey-green back. The females, which are caught in the estuaries of the rivers to which they return to spawn, are the source of caviar which may amount to 22 kg from a single fish. There are about 24 species but the important ones in order of size are the sterlet and the sevruga, osciotre, common and beluga sturgeon.
