Abstract: An investigation was made on the parasitic infestation of Nile Tilapia Oreochromis niloticus collected from four different sources, i) Taranga Tonu pond of Patuakhali Science and Technology University (PSTU), ii) Nilkomol pond of PSTU, iii) Pirtala fish market of Dumki upazilla and iv) Chanchal hatchery in Bauphal upazilla during August 2016 to February 2017. A total of 80 host fishes were examined of which 52 fishes were found infected by protozoan and metazoan parasites. A total of 3093 parasites belonging to nine genera (three ectoparasites and six endoparasites) were recorded from the investigated samples. Among the parasites, two were protozoan parasites, one was monogenic parasites and six were digenetic parasites. Endoparasites were higher than the ectoparasites. In terms of endoparasite and ectoparasites, Capillaria and chilodonella respectively were found in highest numbers. The maximum prevalence were recorded in Taranga tonu pond (100%) and Nilkomol pond (75%) and lowest was recorded in hatchery source (20%). The highest number of parasites, mean intensity and abundance was observed in the Taranga tonu pond probably due to the poor water quality and associated with the sewage lines and the lowest in numbers of parasites, mean intensity and abundance was observed in the Hatchery.
