Sevruga caviar length. It is native to the Black, Azov, Caspian and Aegean Sea basins although it has been extirpated throughout most of its range. Because the Stellate sturgeon was once the most common and fastest to reproduce, this made Sevruga caviar the most commonly found of the sturgeon caviars, and the most inexpensive of the three main types of sturgeon caviar - Beluga, Osetra and Sevruga. It’s calculated that about half the caviar production comes from Sevruga. Sevruga caviar eggs are a pearlescent grey, and smaller in size than other sturgeon.

Sterlet become self-sustaining. Today, the majority of the international trade involves sterlets from aquaculture. The sterlet's main source of food is benthic organisms; they commonly feed on crustaceans, worms, and insect larvae. The sterlet commonly reaches the age of 22 to 25 years. Males reach sexual maturity at 3–7 years old and females at 4–12 years old. Spawning occurs from the middle of April to the beginning of June. Females may lay from 15,000–44,000 eggs, at water temperatures preferably 12–17 °C (54–63 °F). Sterlets require relatively large ponds with good water conditions, and may get entangled in plants such as blanketweed.
