Optimized technology of large-scale cryopreservation of sturgeon sperm

To preserve the genetic diversity of sturgeon during artificial reproduction, the use of cryopreserved sperm samples stored in cryobanks is becoming increasingly important. The observed trend towards a decrease in the quality of seed material from fish farms determines the need to improve cryopreservation technologies. Based on the results of experiments conducted over six years on ejaculates of varying quality, the basic technology for cryopreservation of sturgeon sperm that we had previously developed was optimized. The use of optimized technology will allow for the highly efficient freezing of large volumes of sperm for reproductive and biodiversity conservation purposes.
