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

Abstract

Introduction: This study was conducted with the aim of investigating some biochemical
characteristics of semen and sperm indices.
Material & Methods: 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.
Results: 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.
Conclusion: 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.
