Production cycle

Production systems
Seed supply
Males and females are kept separately, because of the different products that are sold from sturgeon rearing. The absence of sexual dimorphism led to the development of several methods of sexing immature fish: biopsy and observations, dosage using plasmatic 11-ketotesterone, and ultrasound scans. This is normally carried out at about 3 years. The males are then sold. The females are kept and grown on for several years until they are mature enough to produce caviar. They are then harvested for meat. Some may be kept for broodstock, for future reproduction.
