Semen characteristics of the endangered cyprinid lake minnow, Eupallasella percnurus (Pall.), from different Polish populations

The aim of the study was to compare the quality and quantity parameters of semen in male lake minnow, (Pallas, 1814), from six Polish populations. Substantial differences among the populations were found in milt volume (36–112 µl) and sperm concentration (4.7–8.0 × 10 ml ). Mean values for sperm mot...

Zusammenfassung:	The aim of the study was to compare the quality and quantity parameters of semen in male lake minnow, (Pallas, 1814), from six Polish populations. Substantial differences among the populations were found in milt volume (36–112 µl) and sperm concentration (4.7–8.0 × 10 ml ). Mean values for sperm motility were similar; however, there were population-related differences in sperm velocity measured with VSL (96.3–127 µm s ). Despite this, the quality of semen in all cases was high and appropriate for both artificial reproduction and cryopreservation.
