Abstract Cirrhunus mrigala is economically important fish species in Myanmar. A total of 50 Cirrhinus mrigala fingerlings were sampled monthly from Yezin fishery Station from September 2018 to August 2019 and parasitic infestation in the gills of fish were examined. Ectoparasites such as Dactylogyrus sp., under the phylum Platyhelminthes and Trichodina sp., and Ichthyophthirius multifiliis under the phylum Ciliophora were recorded. Among all these parasites the most dominant were Dactylogyrus sp. followed by Trichodina sp. and Ichthyophthirius multifiliis. Dactylogyrus sp. infested in the gills with the highest prevalence (80%) in March with the mean intensity 4.3. The highest prevalence of Trichodina sp. (66%) was found in October 2018 and the highest mean intensity was 2.8 in February 2019. However, Ichthyophthirius multifiliis was found only in September with the prevalence (50%) and enormously decreased to 12% in October. Hyperplasia and hypertrophy with presence of numerous inflammatory cells and an accumulation of blood cells were observed at the base of secondary gill lamellae of the fish. The management practices and pond hygiene should be adopted in nursery operation systems of the study area for producing quality fish fry for successful harvesting. |
