Özet
The mineral and organic composition of seminal plasma, physical spermatological parameters and their physiological relationships were investigated in Salmo trutta macrostigma. The seminal plasma contained 121.0 ± 0.37mM/l (Na +), 8.18 ± 0.03mM/l (K +), 7.23 ± 0.03 mg/dl (Ca 2+), 3.19 ± 0.02 mEq/l (Mg ++), 0.48 ± 0.02 g/dl total protein, 6.07 ± 0.06 mg/dl cholesterol, 6.24 ± 0.08 mg/dl triglyceride and 9.97 ± 0.39 mg/ dl urea. The following physical spermatological parameters were found out: sperm volume 13.93 ± 0.84 ml, sperm motility 80.37 ± 2.36%, movement duration 81.47 ± 4.21 s, density 6.02 ± 0.46 × 109/ml, total density 8.85 ± 6.12 × 10 9 and pH 7.53 ± 0.20. Significant positive relationships were determined between motility duration and motility (r = 0.83, P < 0.01) and also between spermatocrit and motility (r = 0.536, P < 0.05). Sperm volume and total density negatively correlated with motility (r = -0.191, P > 0.05 and r = -0.087, P > 0.05, respectively). The Na +, K + and Cl - ions correlated negatively with motility (r = -0.267, P > 0.05, r = -0.152, P > 0.05 and r = -0.461, P > 0.05, respectively). On the other hand, the Ca 2+ and Mg 2+ ions correlated positively with motility (r = 0.114, P > 0.05 and r = 0.040, P > 0.05, respectively). A significant negative relationship was found between motility and urea (r = -0.515, P < 0.05). These parameters should be considered when developing procedures for short-term storage or cryopreservation of the Salmo trutta macrostigma sperm.
