Scientific name
Acipenser baerii
In the water
Native to the great rivers of Siberia, it is now farmed in tanks and ponds, notably in Aquitaine and the Sologne; it cruises the bottom, rooting through silt with its snout.
Season & buying
Farmed year-round; the flesh is mostly sold smoked, while caviar is harvested in late autumn and winter.
Common length
~100 cm
How to identify it
Five rows of bony plates along the body
Pointed snout with four barbels ahead of the mouth
Asymmetric tail, shark-like

On the plate

White, firm, meaty flesh close to veal and a little fatty; its roe makes a caviar with nutty notes.

Avoid: Treating it like a delicate fish: the dense flesh needs slow cooking and a rest, or it stays rubbery.

On farms, young sturgeon are sexed by ultrasound, because it takes years before the females carry their eggs.
