The investigation of semen spermatological and biochemical parameters in wild and cultured common carp (Cyprinus carpio Linnaeus, 1758)

In this study، semen spermatological and biochemical parameters in wild and cultured common carp were investigated. Na+ (Mmol/l) and K+ (Mmol/l) ions were measured by flamephotometere and Ca2+ (mg/dl)، Mg2+ (mg/dl)، blood serum organic composition such as glucose (mg/dl)، cholesterol (mg/dl) and total protein (g/dl) were measured by spectrophotometere. Duration of sperm motility was measured by stereomicroscope and spermatocrite was measured by micro centrifuge. The results of this study suggested that there were a highly significant difference of Ca2+، Cl-، Na+، K+، total protein، cholesterol، glucose، and pH (P<0. 05) levels between wild and cultured carp but there was no significant difference in seminal plasma Mg2+ (P>0. 05). Also، there were significant differences of spermatological parameters (value of sperm، spermatocrite، sperm density، motility duration and percentage of motile spermatozoa) between wild and cultured common carp (P<0. 05) so that in cultured carp were more than wild carp. This study showed، that sperm quality of cultured carp is better than that of wild carp.
