The concentration and motility of sperm and the osmotic pressure and total protein in the seminal plasma of pikeperch, Sander lucioperca (L.) was determined. The samples investigated were milt from males held under various rearing conditions (ponds, tanks of a closed recirculating systems, cages). The highest percentage of motile sperm was noted in the semen samples from males held in basins, while the lowest percentage of motile sperm and the highest protein content was confirmed in the samples from spawners held in ponds. Sperm motility and the osmolality of the seminal plasma were low in all the spawner groups, this may indicate contamination with urine. As the content of protein rose in the plasma and the sperm concentration increased, so did their motility
