摘要: Summary In the present study, we investigate possibility of spermatozoa motility activation resulted from freeze-thawing, defined by us as spontaneous sperm (SSA) in common carp (Cyprinus carpio L.), Eurasian perch (Perca fluviatilis rainbow trout (Oncorhynchus mykiss), Northern pike (Esox lucius L.) and sterlet (Acipenser ruthenus using cryopreservation methods described previously. To evaluate that, percentage velocity frozen-thawed before after dilution with activating media were used. The SSA phenomenon was found perch, but not pike, sterlet. for characterized 16% (median value) 98 ± 2 μm s−1 (mean ± 0.95 CI), 5% 53 ± 5 μm s−1, correspondingly. Significant decrease observed, when applied thawed carp, while this parameter became significantly increased. We believe that phenomena freeze-thawing processes are species-specific ones.
