%X The purpose of the present study was to analyze changes of ovarian fluid, seminal plasmacompositions, also sperm production characteristics (spermatocrit, sperm density and sperm volume)and sperm motility traits (sperm movement duration and percentage of motile spermatozoa) duringspawning season (February to May) in koi, Cyprinus carpio (Linnaeus, 1758). Ovarian fluid and semensamples were collected from 10 female and 15 male fish in each month respectively. The resultssuggested that percentage of motile spermatozoa, sperm movement duration and sperm volume had notsignificantly changes (P>0.05), but spermatocrit and sperm density shown significant changes (P>0.05)among February, March, April and may. On the other hand, no significant differences were recorded inovarian fluid compositions. Analysis seminal plasma compositions shown that Sodium, glucose and totalprotein significantly changed (P<0.05) between four term, and other seminal plasma compositions hadnot changes (P>0.05) during spawning season. The present study described that evaluation of theseparameters will help in development of the basic knowledge about reproduction biology in koi.
