Winnicki A., Formicki K., 1993. Activation and motility of spermatozoa of vendace (Coregonus albula L.). Acta Ichthyol. Piscat. 23 (2): 147-152.
The number of activated spermatozoa of vendace (Coregonus albula L.) and their motility under natural conditions at the fishing ground were determined. The percentage of spermatozoa activated upon contact with water was found to be relatively high, and motility period (turbulent and smooth phase of progressive movement, and oscillatory movement) - fairy long, i.e. exceeding 2 min.
