Determination of sperm properties and parameters between Acipenser ruthenus and Acipenser gueldenstaedti

This present resent study investigated sperm motility parameters (sperm motility duration and sperm motility percentage), spermatocrit, density of sperm and some biological factors such as sperm seminal plasma indices (ionic and organic composition) in 8 Acipenser ruthenus and Acipenser gueldenstaedti broodstocks. Sperm mobility duration length, percentage of sperm mobility, spermatocrit, density of sperm were measured 185±10.23 s, 90.00±2.25 %, 2.60±0.19 %, 2.42 × 0.30, respectively in A. ruthenus and 210±11.12 s, 90.33±2.16 %, 2.77±0.24 %, 2.63±0.18, respectively in A. gueldenstaedti. The concentrations of Sodium (Na+), Potassium (K+), Calcium (Ca2+) and Magnesium (Mg2+) ions were determined 88.56±7.24, 4.24±0.32, 7.52±0.29 and 2.38±0.26 Mm L-1, respectively in A. ruthenus and 90.84±6.12, 4.65±0.21, 7.31±0.34 and 2.44±0.31 Mm L-1, respectively in A. gueldenstaedti. The concentrations of serum cholesterol and glucose were calculated 48.74±5.46 and 27.90±2.57 mg ml-1, respectively in A. ruthenus and 47.53±4.22, 28.63±2.31 mg ml-1 respectively in A. gueldenstaedti. In addition, seminal plasma of A. ruthenus and A. gueldenstaedti were estimated 1.53±0.30 and 1.58±0.34 mg/dl protein, respectively. The results of this study showed that there is a significant difference between sperm motility duration in A. ruthenus and A. gueldenstaedti. No significant differences were observed between other biochemical and spermatological parameters in A. ruthenus and A. gueldenstaedti.
