Overview
Family : Sturgeons ; Feeds on chironomid larvae, oligochaetes and larvae of caddis flies[1]. Baikal sturgeon largely inhabit the areas of Lake Baikal's major tributaries: the delta zone of the Selenga River , Proval Bay , Chivyrkuy and Barguzin Buys. The sturgeons migrate widely throughout the whole lake alongside the coastal line , swimming into bays and coves . In former times, the sturgeons caught used to weigh about 125 kg , yet, they grow slowly and mature late. Length above is assumed, needs to be replaced (RF).

Description
Family Acipenseridae
Cold to temperate waters of the Northern Hemisphere. Anadromous or restricted to freshwater . Body with 5 rows of scutes . Mouth inferior and protractile. Four barbels anterior to mouth. Less than 50 gill rakers. Adults toothless. Large swim bladder. Attain 4.2 m or longer . Important for their meat and roe . Nearly all species are endangered or threatened.The family Acipenseridae belongs to the Class Actinopterygii (ray-finned fishes ) and the Order Acipenseriformes. It contains 4 genera and 23 species. It may be found in Marine , Brackish , and Freshwater environments and is primarily Peripheral/diadromous. Some members of this family are used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is subcarangiform. Compared with other fish, the activity level of this family tends to be sluggish. Members of this family have been dated back to the Cretaceous period. This family may be found from 78° n to 24° s and 180° w to 180° e. Etymology of this family name : Latin, acipenser = sturgeon . 1853
