Název v původním jazyce

Changes of sperm morphology, volume, density and motility and seminal plasma composition in Barbus barbus (Teleostei: Cyprinidae) during the reproductive season

Popis výsledku v původním jazyce

Eighteen spermiating males were randomly selected from a hatchery-reared stock and electronically tagged to record changes in their sperm quality parameters (spermatozoa morphology, ultrastructure and motility, ionic composition and osmolality of the seminal plasma, and sperm volume and density) during the spawning season. Stripping was performed at the beginning of March, April and May. The Barbus barbus spermatozoon has a head without acrosome, a midpiece with 4?6 mitochondria and proximal and distalcentrioles, and a flagellum with the typical 9+2 pairs of microtubules. Apart from posterior width of the midpiece, morphological and ultrastructural parameters changed significantly during the reproductive season; generally by decreasing toward the endof reproductive season. Sperm volume also decreased from 0.42 in March to 0.15 ml in May, and density from 18.81 in March to 12.45 x 109 spz ml-1 in May. Osmolality (mOsmol kg-1) was 268 ? 4, 276 ? 2 and 268 ? 2 in March, April and May re
