The prevalence of infection appeared 88.9% (45 specimens). <em>Lernaeacruciata</em>parasites were isolated from origin of fins, gill opercels and body surface. Frequency of parasite on each fish appeared 1 or 2 which mostly attached to branch and under operculum (45%) and base of pectoral and anal fins (43%). The <em>L. cruciata</em> may have been translocated into the Maharloulake Basin by an exotic <em>Poecilid</em>; <em>Gambusiaholbrooki</em>. Sever infection of this endangered endemic fish species warns that urgent reactions should be taken for conservation of Farsi tooth carps in area.
