Chilodonella

Chilodonella

 

(also Chilodon), a genus of protozoans of the subclass Holotricha of the class Infusoria. Several species are free-living inhabitants of freshwaters; Ch. cyprini, an ectoparasite of freshwater fishes that lives on the gills and skin, is widespread. In the USSR it is found in the central, western, and northwestern regions of the European part, as well as in Western Siberia and Altai Krai. The mass development of Chilodonella, which occurs when fish are underfed, produces chilodonelliasis, a severe disease that sometimes results in death. The optimal temperature range for the development of Chilodonella is 5°–10°C. The main preventive and control measures that can be undertaken at fish farms is the provision of sufficient food to fish fry and the administration of saline baths (5 percent NaCl) prior to placement of the fry in hibernating ponds.

Studying the Prevalence of Chilodonella in Fish Ponds of Sistan Region in Iran.
To implement this project, studying Chilodonella in Sistan ponds including warm and cold water was carried out in the early autumn of 2010 in collaboration with the Fishery office of Sistan region.
In this project, both comparing the percentage of fish infected with Chilodonella and obtaining more accurate results of fish in terms of other protozoan parasites such as Trichodina, Ichtyopoda negatrix and Lernae were studied.
3% (n = 19) were parasitised by at least one parasite species as follows: Ichthyophthirius multifiliis Fouquet, 1876 (Protozoa: Ciliophora), Chilodonella Strand, 1926 (Protozoa: Ciliophora); Cosmetocleithrum gussevi Kritsky, Thatcher and Boeger, 1986, Cosmetocleithrum confusus Kritsky, Thatcher and Boeger, 1986, Cosmetocleithrum parvum Kritsky, Thatcher and Boeger, 1986 and Cosmetocleithrum sp.

In the present study, 400 Nile tilapia (Oreochromis niloticus) were collected from farms in Riyadh, in the central region of Saudi Arabia, and examined for the incidence of Chilodonella infestation.
The protozoans observed in the samples were Paramecium, Stylonychia, Euplotes, Chilodonella, Colpoda, Cyclidium, Metopus, Plagiopyla, Tachysoma, Tetrahymena, Vorticella, Oxytricha, Spirostomum, Amoeba and Spathidium.
