Sturgeon East Siberian The appearance of the sturgeon has a specific look. Its spindle-shaped body, elongated in front into a relatively small, conical snout, is so peculiar and remarkable that it is impossible to confuse the sturgeon with any other fish. He has a lower, transverse mouth. In the caudal fin, the upper lobe is much larger than the lower one. On the body, five rows of bone plates - bugs are clearly visible. The color of the sturgeon is not bright: the back and fins are dark brown, the belly is yellow-white. Occasionally there are gray sturgeons with a bluish tint. Favorite places of semi-anadromous sturgeon are deep sections of channels, with a fast current, pebble and silted soil. Sturgeon spawning migration begins in the second half of June and continues until September. In the river, producers spend the winter in wintering pits, often with sterlet, creating significant accumulations there. The sturgeon becomes sexually mature rather late: females mature at the age of 21-25 years with a length of 85-100 cm and a weight of 4.5-8 kg, males - 2-3 years earlier with smaller sizes. Sturgeon spawns several times throughout its life. The intervals between eggs are at least 5-6 years. Sturgeon spawns in June - early July at a water temperature of 8.5-17 ° C. The caviar is sticky, swept out onto pebble soils. There are usually more males in the spawning grounds. The absolute fertility of the Siberian sturgeon ranges from 50 to 700 thousand eggs and depends on the age and size of the fish. The development of eggs continues for 7-12 days. Spawning fish begin to immediately slide downstream, to their places of permanent residence (delta, lip). males - 2-3 years earlier with smaller sizes.

Over the past 40 years, there have been isolated cases of detection of a sturgeon with a body length of more than 2 m and a mass of slightly more than 100 kg. In modern catches, the average size of sturgeon does not exceed 100-120 cm in length and 8-12 kg in weight. Due to the small number and the danger of complete extinction, the sturgeon is prohibited for commercial use. Its catch is allowed only on a licensed basis, that is, under one-time nominal licenses at a specified time and in certain places. The restoration of the sturgeon population is possible by means of its artificial breeding with a prerequisite for the preservation of natural reproduction. Preservation of natural spawning will allow to have in the spawning stock of fish that have spawned several times, which produce the greatest amount of high quality eggs, providing large and viable offspring.
