Caviar Caviar Caviar (less often, caviare) is a delicacy consisting of salt-cured roe of the Acipenseridae family.

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.
