The composition of the organic compounds of the seminal fluid, pH values and osmolalities were investigated in three cyprinid species, the bleak ( Alburnus alburnus ), the chub ( Leuciscus cephalus ) and the zaehrte ( Vimba vimba ). The seminal fluid contains monosaccharides (glucose, fructose, galactose, xylose), lipids (cholesterol, fatty acids, phosphatidylcholine, glycolipids) and proteins, and exhibits activities of acid phosphatase, β‐glucuronidase, proteases and to some extent of alkaline phosphatase. The composition of free amino acids reveals species specific differences.
