Abstract

This research provides data concerning the biochemical (ionic and organic) composition of sperm of the mirror carp (Cyprinus carpio) and its relationship to spermatozoa motility. Seminal plasma contained 67.12 +/- 1.06 mM/l Na+, 105.1 +/- 2.24 mM/l K+, 7.85 +/- 0.67 mg/dl Ca(2+), 2.61 +/- 0.11 mEq/l Mg(2+), 0.14 +/- 0.002 g/dl total protein, 10.3 +/- 1.01 mg/dl triglyceride, 6.83 +/- 0.72 mg/dl cholesterol, and 54.72 +/- 3.49 mg/dl urea. A positive relationship (p<0.05) was determined between Na(+) and motility (r = 0.522). On the other hand, Ca(2+), K(+), and Mg(2+) ions negatively correlated (p>0.05) with motility (r = -0.565, r = -0.160, and r = -0.184, respectively). Spermatozoa motility correlated negatively (p>0.05) with protein (r = -0.233), triglyceride (r = -0.348), and urea (r = -0.331) but positively with cholesterol (r = 0.012). This information will help to develop cryopreservation procedures, to meet species-specific extender requirements, and to optimize artificial fertilization procedures in mirror carp.
