ABSTRACT. The aim of the study was to determine the basic quality parameters and selected biochemical markers of asp, Aspius aspius (L.), semen after spermiation was stimulated with Ovaprim and Ovopel. Sperm motility and concentration, osmotic pressure, total protein content, and activities of acid phosphatase (AcP), lactate dehydrogenase (LDH), and b-N-acetylglucosaminidase (b-NAG) were determined. It was revealed that higher sperm motility and concentration and higher seminal plasma protein content were obtained after stimulation with Ovaprim. The osmotic pressure of the seminal plasma estimated for males following the administration of Ovopel was higher than after they had been treated with Ovaprim. It was determined that enzyme activity in the seminal plasma of the fish stimulated with Ovaprim was higher in comparison with results obtained after they had been treated with Ovopel. Significant, positive dependencies were confirmed between the concentration of sperm and the total protein content in the seminal plasma (r2 = 0.492) and the activity of b-NAG (r2 = 0.779); among the total protein content in the seminal plasma and the activities of AcP (r2 = 0.476), LDH (r2 = 0.564), and b-NAG (r2 = 0.738); and between the activities of AcP and LDH (r2 = 0.483) and between the activities of LDH and b-NAG (r2 = 0.844).
