•      Grading and selection of caviar females;
•      Installation work and preparation of the wintering complex;
•      Adaptation of fish and their stocking for wintering;
•      Systematic monitoring of the hydrochemical regime of the water, including measurement of temperature and dissolved oxygen concentration, as well as assessment of other key water quality indicators necessary to maintain optimal fish rearing conditions;
• Carrying out the important and key work — organizing and ensuring optimal wintering conditions for caviar females to facilitate the production of high-quality food caviar.
