The infestation of pond fish ciliated infusoria

Recently in fish farms of Ukraine, the cases of emergence and spread of protozooses. caused by the ciliated infusoria. The spread of disease contributes to the pollution of waters with organic substances, violation of fish and animal health requirements.

For modern aquaculture is characterized by a sharp deterioration of water quality in ponds. This considerably weakens the body of fish, lowers its resistance to diseases, promotes the accumulation of pathogenic microorganisms, which when tight crop of fish raises the risk of a protozoal disease.

We investigated parasitological situation in feeding and nursery ponds of fisheries Krinichansky. This is a full-cycle farm with a cascading arrangement of ponds. The total area of the ponds is 465 ha. Water is pumped from a selection of water from Dneprodzerzhinsk reservoir and Wet of the river Sura. The objects of fish farming are carp and silver carp, which are grown in polyculture. We used the classical method of complete parasitological dissection of fish ( Bykhovskaya-Pavlovskaya. 1969). When conducting parasitological studies in carp yearlings during the summer period were found several species of ciliated infusoria: Trichodinella epizootica. Trichodi na acuta and Ichthyophthirius multifiliis. Extensionactivity (EI) tradename reached 100 %, the intensity of invasion (AI) – 4,5±1,20 instances on the fish. Continue reading
