Abstract :In this study, some serum factors in male and female Caspian kutum insert ignore into journalissuearticles values(Rutilus frisii kutum); broodstocks were investigated. The estimated values were compared between male and female fish of various age groups. A total of 80 mature fish insert ignore into journalissuearticles values(40 males and 40 females); were randomly caught from the Shirood and Tajen rivers insert ignore into journalissuearticles values(southern Caspian Sea); during spawning season. Blood samples were then taken from the caudal peduncles and the serum biochemical parameters were measured according to common laboratory methods. Cholesterol levels showed significant differences insert ignore into journalissuearticles values(P < 0.05); between male and female broodstocks from the Tajen River, as well as between male and female kutum of the Tajen and Shirood rivers. Comparison of the estimated serum factors with the fish ages revealed no significant changes insert ignore into journalissuearticles values(P > 0.05);. A high correlation was found between total protein and weight in fish from both rivers based on Pearson`s correlation. This study suggests that male and female variations in blood factors should be taken into account when these parameters are used to assess sex, age, and spawning sites.
