The effects of semen ion ratios on spermatological parameters in carp (Cyprinus carpio)

In this study, the effects of semen ion ratios on spermatological parameters and pH in carp were evaluated. The Spermatological and biochemical parameters from 14 males fish in the laboratory by microcentrifuge, stereomicroscope, spectrophotometer, flame photometer and ph meter were measured. Na+/K+, Na+/Ca2+, Na+/Mg2+, K+/Ca2+, K+/Mg2+ and Ca2+/Mg2+ ion ratios of each treatment were divided into three groups. The results of this study showed that sperm quality increased with increasing of Na+/K+ but decreased with increasing of Na+/ Ca2+, K+/ Mg2+ and K+/Ca2+. Also, change of ion ratios Ca2+/Mg2+ and Na+/Mg2+ has no influence on sperm quality. The refore, it can be concluded that ion ratios are effective in increase or decrease of sperm quality
