The present study was conducted to evaluate seminal plasma composition, spermatological parameters and their relationships in scaly carp (Cyprinus carpio). Seminal plasma contained 71.18 +/- 3.40 mML(-1) (Na(+)), 87.48 +/- 4.42 mML(-1) (K(+)), 10.64 +/- 1.50 mg dL(-1) (Ca(2+)), 2.57 +/- 0.19 mEq L(-1) (Mg(2+)), 0.12 +/- 0.04 g dL(-1) total protein, 1.43 +/- 0.02 mg dL(-1) glucose, 7.82 +/- 2.60 mg dL(-1) triglyceride, 6.27 +/- 2.32 mg dL(-1) cholesterol, 24.45 +/- 7.98 mg dL(-1) urea. The following spermatological parameters were found: sperm volume 13.17 +/- 5.39 mL, sperm motility 63.18 +/- 7.16%, movement duration 56.81 +/- 20.32 s, sperm concentration 29.637 +/- 1.07 x 10(9) mL(-1), total sperm concentration 419.200 +/- 29.62 x 10(9) and pH 7.59 +/- 0.74. The K(+) and Ca(2+) ions correlated positively with motility (r = 0.215, p>0.05 and r = 0.048, p>0.05), respectively. On the other hand, Na(+) and Mg(2+) ions correlated negatively with motility (r = -0.067, p>0.05, r = -0.407, p>0.05), respectively. Significant correlations were observed between K(+) and Na(+) (r = -0.695, p<0.05), protein and triglyceride (r = 0.786, p<0.01), protein and cholesterol (r = 0.936, p<0.01), triglyceride and cholesterol (r = 0.802, p<0.01). These parameters can be used to prepare species-specific extenders for short-term storage and cryopreservation of scaly carp sperm.
