Most of the ۴ species of helminthes were found in the intestine and body cavity of the examined fishes. The helminthes found was composed of ۲ digenetic Trematodes (Lepocreadioides zebrine, Allocreadium brachirusii) all adults, in the intestine. The general prevalence of Lepocreadioides zebrini and Allocreadium sp. was in the intestine, ۵۸% and ۷۳% respectively, nematode Hysterothylacium aduncum with a prevalence of ۲۳% was the only cestod Protocephalus sp. with ۱۶%, except Pterobothrium sp., which was reported previously.
