In this study, the effects of hormonal Ovaprim, HCG and pituitary extract injection on biochemical parameters of seminal plasma (Na+, K+, Ca+, Mg2+, cholesterol and glucose) in snow trout (Schizothorax zarudnyi) males were compared. Twenty males at Zahak hatchery with a body weight of 784±77 g were randomly assigned to four treatment groups. The spermiation of males was stimulated with ovaprim, HCG, cPG and saline physiological (control) at the following doses: 0.3 ml/kg, 400IU/kg, 0.2 mg/kg and 0.3 ml/kg, respectively. The results showed that there were a significant difference of seminal plasma Na+, K+, glucose and cholesterol among treatments (P<0.05). As the highest value of Na+, K+, glucose and cholesterol observed in ovaprim treatment (91.10±3.14 mmol/lit, 78.00±3.43mmol/lit, 0.043±0.03 mg/dl and 0.073±0.03 mg/dl respectively). Likewise there was a highly significant difference of seminal plasma Ca+ among treatments (P<0.05), as the highest value of Ca+ observed in ovaprim and pituitary extract treatments (7.46±0.99 and 7.17±0.51 mmol/lit). The results showed that there were no significant difference in Mg2+ among treatments (P>0.05). The present study demonstrated that ovaprim, HCG and pituitary extract have different effects on biochemical parameters of seminal plasma in snow trout, and ovaprim has more effects on biochemical parameters of sperm than HCG and pituitary extract.
