Abstract
The energetic status of fresh sperm of wild Atlantic salmon (Salmo salar L.) was presented in selected males (n=10) with motility rate ≥80%. Purine and pyridine nucleotides: adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), guanosine triphosphate, guanosine diphosphate, guanosine monophosphate, inosine monophosphate, nicotinamide adenine dinucleotide and nicotinamide adenine dinucleotide phosphate; nucleosides: adenosine, guanosine and inosine; bases: hypoxanthine, xanthine and uric acid were determined using the high‐performance liquid chromatography method. The average value of adenylate energy charge in the group was 0.77 ± 0.10, and the mean total adenine nucleotide content (TAN) was 65.1 ± 18.3 pmol × 10−6 spermatozoa. The mean concentrations of ATP, ADP and AMP were 43.5, 11.8 and 9.9 pmol × 10−6 spermatozoa respectively. The concentrations of the other energetic nucleotides studied were lower. In all males studied (n=23) with a motility rate from 0% to 95%, no statistically significant correlation between the per cent of motile sperm and ATP concentration was found (Rs=0.35), whereas the correlation between the per cent of motile sperm and ADP was statistically significant (Rs=0.60). A negative correlation was found between hypoxanthine and the per cent of motile spermatozoa (Rs=−0.44). Our results suggest that hypoxanthine is the final product of salmon spermatozoa of adenine nucleotide catabolism.
