چکیده
In the present investigation, infection of Lernaeacruciata parasite is reported in Farsi toothcarp (Aphaniusfarsicus) collected from Maharlu Lake basin in 2014. The prevalence of infection appeared 88.9% (45 specimens). Lernaeacruciataparasites 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 L. cruciata may have been translocated into the Maharloulake Basin by an exotic Poecilid; Gambusiaholbrooki. Sever infection of this endangered endemic fish species warns that urgent reactions should be taken for conservation of Farsi tooth carps in area.
