Influence of Acoustic-Mechanical Impact on the Reproductive Qualities of Sturgeon Sperm during Cryopreservation

The use of various types of stimulation of fish spermatozoa in order to increase the survival of defrosted cells is a promising direction in the field of low-temperature preservation. In this work, the use of acoustic-mechanical effects on the sperm of sturgeons (in particular, sterlet) was studied for the first time. The technical characteristics of the assembled experimental device for acoustic-mechanical effects on fish sperm are given. As a result of this work, the optimal parameters of exposure to increase the preservation of defrosted germ cells were selected.
