Relationships between reproductive characteristics in male Vimba vimba L. and the effects of osmolality on sperm motility

Original language description

In Vimba vimba, GSI, sperm volume, and spermatozoa concentration range from 3 4-7 4 %, 0 1-1 1 ml, and 13.3-34 8 x 10(9) spz ml(-1), respectively. Gonad mass (r = 0 90) and sperm volume (r = 0.35) significantly correlated with weight of males Significantcorrelation was also found between gonad mass and length of males (r = 0 85) Sperm motility (r = 0.99) and velocity (r = 098) significantly decreased after activation in Tris-HCl 20 mM, pH 8 5 Osmolality of the seminal plasma was 273 2 mOsmol kg(-1) Sperm motility and velocity were significantly affected by the osmolality of the activation medium (P < 0 01) Hyper-osmolality compared to seminal plasma osmolality totally suppressed the sperm activation. At 15 s post-activation, the sperm motility significantly decreased at 240 mOsmol kg(-1) in KCl or NaCl media The highest sperm motility and velocity (at 60 s post-activation) were observed at 200 mOsmol kg(-1) in NaCl, KCl, or sucrose media In all treatments, the tip of the flagellum of
