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.
Keywords: acoustic-mechanical impact; cryopreservation; reproductive cells of fish; sturgeon.
