Beginning in 2007, when our stock reached maturity, we began carrying out the sturgeon breeding process ourselves in the farm’s hatchery, with meticulous attention to preserving the genetic purity of the Osetra strain.
In 2021, we began using genetic markers to distinguish male from female sturgeon through a technology developed in our own laboratory. The method uses DNA samples taken from the fish’s fin and replaces previous techniques based on ultrasound and endoscopy. Our research team continues to develop new capabilities based on genetics and DNA analysis.
The farm’s diverse range of growing ponds allows us to provide the fish with optimal living conditions at every stage of development. We maintain ideal water quality and temperature through three different water systems, supplied by clear, fresh water directly from the Dan Spring together with water from reservoirs adjacent to the farm. Close monitoring and precise control over the source and rate of water exchange enable us to maintain optimal growing conditions and ideal water temperatures throughout the year.
We continuously monitor oxygen levels, water temperature and the rate of water exchange in the ponds. The data is transmitted to our control center for analysis, where alerts are issued and oxygen generators are activated automatically whenever necessary.
Sustainable aquaculture begins with the spawning process carried out on the farm and with the creation of optimal habitats for the sturgeon. Maintaining water quality, raising the fish in spacious ponds, and ensuring optimal environmental conditions, nutrition and health monitoring allow the sturgeon to grow and develop in a stress-free environment.
During caviar season, we perform ultrasound examinations on thousands of female sturgeon. These examinations allow our team of biologists to determine the caviar’s stage of readiness and identify mature fish. The caviar is harvested at precisely the right time, and only when its quality meets KARAT Caviar’s exacting standards.
