Key identification features
- Robust, thick-bodied build compared to more slender sturgeon relatives
- Short, blunt, conical snout

- Five rows of moderately sized bony scutes
- Can reach up to 8 feet and well over 200 pounds
Common look-alikes
- Sterlet: much smaller and slimmer, with distinctly fringed, feathery barbels versus the Russian Sturgeon's smooth ones.
- Stellate sturgeon: has a dramatically elongated, sword-like snout that is far longer and thinner than the Russian Sturgeon's short blunt snout.
- Beluga sturgeon: grows substantially larger with a broader, more shark-like head and a bigger, more gaping mouth than the Russian Sturgeon.
Where you'll see one
Russian Sturgeon are anadromous, living mainly in the Caspian, Black, and Azov seas and ascending large rivers such as the Volga, Don, and Danube to spawn on gravel or rocky substrate. Populations have declined sharply due to overfishing and dam construction blocking spawning migrations.
Frequently asked questions
How do I tell a Russian Sturgeon from a Sterlet?
Check the barbels and body size: Russian Sturgeon have smooth-edged barbels and a much bulkier body, while Sterlet barbels are fringed and the fish stays under about 3 feet.
What distinguishes a Russian Sturgeon from a Beluga Sturgeon?
Head and mouth shape are key — Beluga Sturgeon have a much wider, more shark-like head and gaping mouth, while the Russian Sturgeon's snout and mouth stay proportionally smaller and blunter.
