Abstract
Levels of biochemical parameters in seminal plasma and physical parameters of rainbow trout (Oncorhynchus mykiss) semen were determined and compared. Seminal plasma contained 80.51±31.48 mmol/l Na+, 46.21±12.58 mmol/l K+, 4.65±1.57 mg/dl Ca2+, 3.48±1.18 mEq/l Mg2+, 112.5±25.93 mmol/l Cl-, 1.33±0.76 mg/dl glucose, 0.15±0.09 g/dl protein, 2.55±2.47 mg/dl cho- lesterol, 8.0±2.84 mg/dl triglyceride, and 31.65±40.78 mg/dl urea. Semen volume was 19.9±21.43 ml, spermatozoa motility 60.0±30.09%, duration of spermatozoa movement 174.0±1.82 s, spermatozoa concentration 1.52±0.70 x 109/ml, total spermatozoa number 44.25±64.59 x 109, and pH 6.7±0.25.
There were significant positive correlations between semen volume and Na+ (r = 0.667, p<0.05), total spermatozoa number and semen volume (r = 0.977, p<0.01), total spermatozoa number and spermatozoa concentration (r = 0.652, p<0.05), Na+ and Cl- (r = 0.733, p<0.05), Na+ and triglyceride (r = 0.632, p<0.05), K+ and protein (r = 0.728, p<0.05), and Ca2+ and protein (r = 0.685, p<0.05). Significant negative correlations were found between Cl- and glucose (r = - 1.00, p<0.05), and triglyceride and urea (r = -0.716, p<0.05). Consequently, although there were no definite correlations between biochemical and spermatological parameters, it was observed that a higher Na+ content has a positive effect on semen volume.
