Research of ectoparasitic infestation on certain ornamental fish

In this study we aimed, certain ornamental fish which the members of Cichlidae including the electric yellow (Labidochromis caeruleus), powder blue cichlid (Pseudotropheus socolofi), electric blue hap (Sciaenochromis fryeri) and the members of Poecilidae including yucaten molly (Poecilia velifera), white molly (Poecilia sphenops) were examined for ectoparasitological. The research period is 12 months. Sampling was done from the company in the first and second week of each month. Sampling continued from December 2013 until November 2014. 600 fish samples were used. At each sampling period, the water temperature, dissolved oxygen and pH were measured. In laboratory conditions, fish were examined from the outside aspect. After examination, smears prepared from body surface, fins and gills of fish and it was examinated under the light microscope. During study period, it was detected 6 different parasite species include that Ciliophora (Vorticella sp., Tetrahymena sp., Trichodina pediculus ve Trichodina heterodentata), Rotifera (Euchlanis sp.) and Gastotricha (Chaetonotus sp.). Trichodina pediculus, Trichodina heterodentata, Euchlanis sp. and Chaetonotus sp. are new records for Turkey.
