Diagnosis. Distinguished from other species of Acipenser and Sterletus in West Asia by: ● 20–49 fan-shaped gill rakers terminated by several tubercles / ○ lower lip interrupted in middle / ○ 10–20 dorsal scutes / ○ 32–62 lateral scutes / ○ 7–16 ventral scutes / ○ barbels not fimbriate / ○ tetraploid. Size usually up to 2000 mm TL and 210 kg.
Distribution. Siberia (from Ob to Kolyma drainages, Lake Baikal). Aquaculture has resulted in deliberate and accidental releases, especially in Caucasus. No known established populations in West Asia.
Habitat. Deep parts of large rivers with moderate to rapid currents. Spawns in main channel over stone-gravel or gravel-sand bottom in strong current.
