Description
  • Seminální plazma (osmolalita a iontové složení), koncentrace spermií a jejich motilita byly studovány u jesetera perského. Důvodem sledování těchto znaků bylo posouzení kvality seprmatu při několikerém odběru. Vzorky spermatu byly odebírány při umělém výtěru z 9 samců injikovaných jeseteří hypofýzou v dávce 50-70 mg/kg, a to 24 hodin po injikaci (první odběr), 12 hod po prvním odběru (druhý odběr) a 12 po druhém odběru (třetí odběr). Koncentrace spermií a osmolalita seminální plasmy se významně snižovaly při jednotlivých odběrech. Koncentrace iontů Na, K a Cl převládaly v seminální plasmě při různých odběrech a žádné rozdíly v jejich koncentraci nebyly zaznamenány. Procento pohyblivých spermií (15-30 s po aktivaci) a celková doba pohyblivostui spermií se významně snižovaly při následujících odběrech. Zajímavé bylo, že vliv následného odběru na pohyblivost spermatu byl vyšší než použití různých aktivačních médií. Výsledky dále ukázaly výzmanmé zvýšení procenta pohyblivosti spermií i dobu jejich pohybu (cs)
  • Seminal plasma indices (osmolality and ionic composition), spermatozoa concentrations and sperm motility were studied in the Persian sturgeon, Acipenser persicus in order to use these semen biomarkers to measure performance in terms of sequential stripping effects. Semen samples were collected by hand stripping from nine induced males injected intramuscularly with sturgeon pituitary homogenized extract at dosages of 50-70 mg Kg-1 body weight, 24h after spawning induction (first stripping), 12h after first stripping (second stripping) and 12h after second stripping (third stripping). The spermatozoa concentration and osmolality of the seminal plasma decreased significantly with subsequent stripping. The Na+, K+ and Cl- ions concentrations were predominate in the seminal plasma at different stripping times. But, there were no significant differences between ions concentrations at different stripping frequencies (P>0.05). The percentage of motile spermatozoa (after 15-30 sec post-activation) and total
