Abstract
    Despite the importantance of fish helminthic infestation due to economic losses and public health threats, our knowledge is limited in its extent. The present study was conducted to identify helminth parasites and carried out on 100 specimens belonging to four species of the Persian Gulf fishes including Scomberomorus commerson, Nemipterus japonicus, Trichiurus lepturus and Pomadasys kaakan, which were sampled from Bandar Abbas port in summer 2012. The worms were fixed in 70% ethanol, stained and identified. The species which have been identified were as follows: 1 digenetic Trematode (Dinosoma rubrum) with the frequency of  3% from  the stomach of T. lepturus, 2 species of nematoda (Anisakis sp. and Spirocamallanus sp.)., Anisakis sp. with the frequency of 4 % from the intestine and  stomach of  S. commerson and the body cavity of N. japonicus  and Spirocamallanus sp with the frequency of 2% from the intestine of T. lepturus, 1 species of cestoda (Grillotia sp.) with the frequency of 5% and several larval trypanorhynch cestodes with frequency of the 3 % from the stomach wall of  S. commerson. According to the results, the overall frequency of helminthic infestation was 17%, the highest frequency was due to cestodaand the most identified species was Grillotia sp. In this study, Pomadasys kaakan had no helminthic infestation. Based on the results, there was no helminthic infestation in the flesh of fish. More studies should be done to determinate the helminthic infestation and hazards of zoonotic diseases.
