Keywords: carp; trypanosome; cryptobia; infection intensity

Abstract

Experimental studies have shown that in the body of carp yearlings infested with trypanosomes and Cryptobia in the water with a low temperature (4–12°C), intensive aeration and abundant feeding intensity of infection of blood parasites was low. Intensity of infection of the same fish that were kept in water with temperature 20–24°C, poor aeration of water and shortage of food increased. The sharp increase of the intensity of infection with Cryptobia in one of the individuals led to the fish death.
