We farm Osetra - Siberian Sturgeon, Acipenser Baerii (well-known gourmet caviar) and Sterlet, Acipenser Ruthenus (delicious and unduly forgotten tsars' and shahs' caviar).
THE SIBERIAN STURGEON (ACIPENSER BAERII) - OSETRA (from Russian)
is the mostly common farmed for caviar species of Sturgeon. It populates the major Siberian rivers where it got its name. It has its life cycle in freshwater and breeds and reproduces well in aqua systems unlike osetra from the Caspian Sea which is almost impossible to reproduce. Sturgeon eggs are robust and have appealing "caviar" colour and nice and fresh taste.
THE STERLET STURGEON (ACIPENSER RUTHENUS)
is one of the smaller species of sturgeon and is now very rare. Sterlet caviar has disappeared from the market for almost 50 years but is now coming back.The fish is very sensitive to farming but Mottra technology has made it possible. With small grey-golden eggs, the Sterlet caviar was once ranked alongside Beluga by the Russian Tsars, Iranian Shahs and Austrian Emperors in the quality ranking, followed by medium-sized eggs of the Osetra Sturgeon.
