Comparison of some spermatological and biochemical parameters between Huso huso and Acipenser stellatus

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 7 beluga (Huso huso) and Starry sturgeon (Acipenser stellatus) broodstocks. Sperm mobility duration length, percentage of sperm mobility, spermatocrit, density of sperm was measured 310±30.65 s, 93.11±4.31 %, 2.78±0.31 %, 2.76 × 109±0.36, respectively in beluga and 81±23.61 s, 80.63±3.27 %, 2.63±0.23 %, 2.40×109±0.28, respectively in A. stellatus. The concentrations of Sodium (Na+), Potassium (K+), Calcium (Ca2+) and Magnesium (Mg2+) ions were determined 96.24±8.47, 3.34±0.40, 8.66±0.44 and 1.15±0.15 Mm L-1, respectively in beluga and 95.33±8.40, 4.23±0.28, 8.43±0.47 and 2.39±0.24 Mm L-1, respectively in. The concentrations of serum cholesterol and glucose were calculated 12.98±6.77 and 32.67±2.47 mg ml-1, respectively in beluga and 45.68±5.78, 30.43±0.29 mg ml-1 respectively in A. stellatus. In addition, seminal plasma of beluga and starry sturgeon were estimated 1.45±0.27 and 1.49±0.29 mg/dl protein, respectively. The results of study indicated that mobility during length, percentage of sperm mobility and magnesium values had significant difference between beluga and A.stellatus sturgeon. The quality and quantity of sperm in Huso huso are higher than that in Acipenser stellatus. In addition, the magnesium in Acipenser stellatus level was significantly increased compared to Huso huso, but no significant differences were observed between both species.
