Capoeta damascina C. damascina 3. Results (Valenciennes, 1842) ( ) is widely distributed in Iran, Turkey, Syria, Lebanon and i.e. C. damascina Israel. This fish was reported from different areas of Iran Out of 12 (7 females and 5 males) ranging Tigris, Karkheh, Karun, Namak, Isfahan, Kavir, Maharlu, from 103 to 160 mm TL and 85-139 SL, one female (106 mm TL, Gulf, Hormuz, Jaz Murian, Persian Gulf and Kor River. This 85.2 mm SL) was infected by 3 nematode parasites of which fish is considered as one of the commonest fishes found in two creamy white larvae were observed in the abdominal most of basins from Iran. Many local people devour cyprinid cavity and firmly attached to the outer part of intestine, while fish as a food source in their diet[3]. one long filiform adult helminth was extracted from intestine According to literature review the following parasites content while no lesion was observed in the intestinal C. damascina Coelobothrium were observed from : tissues. The recovered parasites were identified as larva of monody Dactylogyrus rohdeianus Dactylogyrus capoetae Contracaecum Capillaria , , , sp. (Anisakidae) and adult of sp.
