At present study, effects of secondary sexual characteristics on biological characters of seminal fluid were investigated. In this study fishes on head tubercles divided to 3 treatments(1: less than 110, 2 : 110 -135 and 3 : more than 135). Sperm duration, spermatozoa motility(%) and K+ of seminal plasma in 3 treatments were significant(p>0.01) but other spermatological and biochemical parameters between treatments were not significant(p; 0.05). The correlation between head tubercles K+ of seminal plasma and sperm movement parameters were positive and significant (p>0.01) and with spermatocrit and sperm volume positive correlation and with pH of seminal plasma were negative correlation significant(p>0.05). Also between body tubercles with pH of seminal plasma was positive correlation significant(p>0.05). But between body tubercles with other spermatological and biochemical parameters of seminal fluid and between head tubercles with Na+, Ca2+, Mg2+, glucose, total protein and cholesterol of seminal plasma were not significant(p; 0.05). Keywords: Sexual tubercles, Biological characters of seminal fluid, Mahisefid(Rutilus frisii kutum)
