In this study, we examined the age-dependent changes of sperm quality parameters and female properties in common carp. As well as, reproductive performance brooders was tested using two age groups male (i.e. 2 3 years old brooders). For aim, were crossed randomly from classes. There significant differences density percentage motile spermatozoa between ages, but duration motility spermatocrit did not differ groups. Some seminal plasma composition such as pH, chloride, acid phosphatase (ACP) alkaline (ALP) showed Female revealed change egg diameter No observed other According to our results, higher fertilization rate (%91) survival (%90) found when males with (P<0.05). Also, highest hatching (%96) larvae length during (P<0.05), while at initiation active feeding (after yolks soc absorption) combination females.
