After finishing of motility, common carp (Cyprinus carpio) sperm is able to re-initiate a second motility period and to fertilize eggs

Original language description

The objective of the study was to compare carp sperm motility performances (sperm velocity and motility rates) from 10 males including fertilizing ability (hatching rates from 10 males and eight females) as a function of time elapsed after sperm exposureto activation medium in two situations: firstly activated sperm and sperm which had terminated swimming and was 're-activated' after incubation in a K+ rich (200 mm KCl) non-swimming solution. In case of both initial (first) and secondly activated spermatozoa, the motility was triggered in hatchery solution (HAS, 11.2 mOsmol) and in carp activation solution (CAS, 128.9 mOsmol) containing 45 mm NaCl, 5 mm KCl, 30 mm Tris?HCl while also adjusted to a pH of 8.0. First time activated sperm showed significantly higher relative motility, sperm velocity and fertilizing ability compared to re-activated sperm. The carp spermatozoa (in either first or second activation) rapidly lost their fertilizing ability as a function of exposure time of spe
