FIELD: fishing and fish farming.
SUBSTANCE: invention relates to fish industry and can be used in artificial reproduction of sturgeon fishes, as well as for creation of low-temperature genetic banks in order to preserve fish biodiversity. Protective medium for cryopreservation of sperm of sturgeon fishes contains sucrose, potassium chloride and cryoprotectors methanol and formamide. Components of the protective medium are taken in the following ratio, wt%: saccharose 0.1; potassium chloride 0.08; methanol 8; formamide 0.5–1; distilled water – balance.
EFFECT: invention provides higher safety of semen fertilizing capacity during cryopreservation due to more effective synergistic composition of protective medium.
