Composition of ovarian fluid in endangered Caspian brown trout, Salmo trutta caspius, and its effects on spermatozoa motility and fertilizing ability compared to freshwater and a saline medium

Original language description

In this study, ovarian fluid composition and its effects on the motility and fertilizing ability of sperm were studied in endangered Caspian brown trout, Salmo trutta caspius, and were compared with a saline activation medium (125 mM NaCl, 30 mM Glycine,20 mM Tris-HCl, pH = 9.0) and freshwater as the control. The ovarian fluid was composed of sodium 164.4 +/- A 4.4 mM l(-1), potassium 1.8 +/- A 0.1 mM l(-1), calcium 0.6 +/- A 0.1 mM l(-1), magnesium 0.4 +/- A 0.02 mM l(-1), chloride 127.4 +/- A 5.9 mMl(-1), total protein 389.5 +/- A 89.6 mg 100 ml(-1), cholesterol 9.3 +/- A 1.2 mg dl(-1), and glucose 3.3 +/- A 0.2 mM l(-1). The percentage of motile spermatozoa and the duration of sperm motility were significantly higher in ovarian fluid (62 +/- A 3%,74.6 +/- A 0.8 s) than freshwater (35 +/- A 4%, 44 +/- A 1 s), but they did not differ significantly from saline medium (56 +/- A 3%, 74.3 +/- A 0.7 s) (P > 0.05). Higher eyeing rates were observed after the activation of sperm in ovaria
