INFLUENCES OF A DIFFERENT QUALITY OF SPERM ON ESTIMATION OF KRYOPRESERVATION OF CARP SPERM

Meaningful influence of a different quality of nativ sperm of carp on the indexes of its safety at estimation of different stages of the chosen method of kryopreservation is set: temperature adaptation of 60?74%, selection of kryoprotector of 51?67%, freezing-thawing 54?65%. It is shown that by a basic limiting factor determining efficiency are 60±5% kryopreservation of carp sperm, there is the chosen mode of freezing, efficiency of realization of which makes 73±3%.
