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.

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.

The present study investigated sperm motility parameters (sperm motility duration, sperm motility percentage), spermatocrit and concentration and some biological aspects of sperm by determination of seminal plasma indices (ionic and organic composition in Beluga, Huso huso,</em>). Survey was done on 8 wild fish and 8 cultured fish during March and April in 2017 in Propagation and Culture of Sturgeons center, Shahid Marjani, in Gorgan Sperm motility duration, sperm motility percentage, spermatocrit and sperm concentration in wild Beluga were measured 310±61.65, 81.11±6.31, 2.33±0.31, 2.50±0.36 and in cultured Beluga were determined 170.43±34.61, 65.63±5.81, 1.26±0.23, 1.41±0.28 respectively. The concentrations of Sodium (Na+), Potassium (K+), Calcium (Ca2+) and Magnesium (Mg2+) ions were in wild Beluga were measured 99.36±9.47, 4.96±0.40, 7.75±0.44 and 1.15±0.15 MmL-1 and incultured Beluga were determined 98.29±10.40, 5.03±0.28, 7.76±0.47 and 2.12±0.24 MmL-1</sup> respectively. The concentrations of cholesterol and glucose in wild Beluga were measured 49.33±8.77, 32.65±2.12 and in cultured Beluga were determined 47.47±4.78, 32.21±1.66 respectively. Also Seminal plasma in wild Beluga and cultured Beluga was contained 1.10±0.27, 1.33±0.29 mg/dl protein respectively. Studies showed that between duration of motility, motility and concentration Magnesium (Mg2+) ions in wild Beluga and cultured there are significant difference.
