Changes of sperm morphology, volume, density, and motility parameters in northern pike during the spawning period

Popis výsledku v původním jazyce

Sexually mature males (BW=1600 +/- 150g and TL=235 +/- 30mm) of northern pike (Esox lucius L.) were randomly selected from a pond to record changes in their sperm quality parameters (spermatozoa morphology, sperm volume, density, and motility parameters) during the spawning season. The morphological and motility parameters changed significantly during the reproductive season with following trends. Only, head width was not changed during the spawning season. The longest spermatozoa and its flagellar length were found at the middle of spawning period (TL=38.24 +/- 0.37m and 35.14 +/- 0.26m) and shortest at the beginning of spawning period (TL=34.81 +/- 0.29m and 32.53 +/- 0.18m). Other morphological characters were always the lowest at the beginning of spawning period. Sperm volume was changed from 0.33 +/- 0.3ml in February, 0.43 +/- 0.2ml in March to 0.24 +/- 0.1ml in April, and density from 16.2 +/- 0.2x109 spermatozoa ml(-1) in February, 19.4 +/- 0.2x109 spermatozoa ml(-1) in March to 4.8 +/- 0.2x109 spermatozoa ml(-1) in April. Same sperm velocity was observed in all spawning terms at 10 and 20s after activation. Higher velocity was found at 30 and 40s after activation in sperm collected at the middle and the end of spawning period. Significantly, higher percentage of motile sperm was observed at 20, 30, and 40s after activation in sperm sampled at the end of spawning period. This study supports the hypothesis that longer spermatozoa swim faster.
