Sturgeon Species on the Volga: Beluga, Sevruga, Sterlet
The Volga was home to several sturgeon species — from giant beluga to shoaling sterlet. Each had its route, season, and market price; together they made the river's "sturgeon wealth."
Beluga is the largest Volga sturgeon. Centuries-old fish reached enormous size; beluga caviar was especially prized. Fishing beluga was strictly seasonal and required the whole artel's strength.
Sevruga is smaller than beluga but still valuable. Its shoals ran closer to shore; sevruga was taken with nets and seines, told apart by body shape and behavior in the water.
Sterlet is the smallest of the "tsar's" trio but no less famous. It was often cooked whole; at markets sterlet ranked with sturgeon as a delicacy.
Differences and Habits
Beluga matures longer and spawns less often; sevruga and sterlet are faster but also sensitive to barriers on migration routes.
Feed base is similar for all — bottom life, small fish — but beluga stays deeper, sterlet shallower and closer to shore.
Fishermen learned to tell species by scale sheen, head shape, and fight in the net — mistake meant loss of price at market.
Fishery and Prices
At auctions and markets beluga cost most; sterlet was more accessible but still above ordinary river fish. Sevruga stood in the middle.
Roe was sorted by species and quality; fake or mixing was cheating the buyer and ruining reputation.
Quotas and bans in the twentieth century touched all species — each declined in its own way, but the trend was common.
State Today
Wild populations of beluga, sevruga, and sterlet are protected. Catch in the wild is banned or extremely limited.
Hatcheries breed sturgeon for river release and legal caviar production — thus genetic diversity is preserved.
Biologists track which species return after fry release; results are mixed, but without hatcheries the situation would be worse.
How to Tell at the Counter
Legal caviar and fish are labeled; documents show hatchery origin. The buyer may ask for a certificate.
The Museum of Sturgeon on the Volga explains species differences — so visitors do not confuse names and understand why each species is protected separately.
Knowing species is part of ecological literacy: the better people distinguish sturgeon, the less demand for doubtful goods.
Why Remember the Trio
Beluga, sevruga, and sterlet are not abstract lines in a handbook. They are three fates of one river, three economies, three ecological histories.
The Volga without sturgeon species would lose part of its name — "sturgeon river."
Preserving each species is a task not only for biologists but for a city that grew on their fishery. The museum reminds us of this on every tour.
