Fifty specimens of tilapias fishes were examined for helminthes parasites. Fishes were collected from the local markets. Of the collected samples ten (20 %) had metacercarial infection in the branchial cavity. The recorded metacercariae were identified as metacercaria belonging genus Clinostomum. The measurements and the morphological features of the recorded parasite are very close to those of the previous studies. However, the full identification of the recorded parasites required further studies to complete the life cycle or using the molecular technique. In conclusion, the preset study documented the existence of Clinostomum sp. infection in tilapias and more studies are need to be undertaken on other fishes and other existing parasites to provide for more information about the current status of parasitic infection among fishes of the local markets
