title: DEVELOPMENT OF CRYOPROTECTIVE MEDIA FOR LOW-TEMPERATURE FREEZING OF STERLET (ACIPENSER RUTHENUS) SPERM
abstract: Purpose. To develop the optimum composition of a cryoprotective solution for freezing sterlet sperm with the use of new and standard constituents and compare the results of the fertilization of eggs with sperm frozen by different ways and in different media.
