Morphological identification of parasitic nematodes in the pickhandle barracuda (Sphyraena jello) and indian halibut ( Psettodes erumei), from the Persian Gulf, Iran

Due to importance of the Persian Gulf fishes as main protein sources, study of fish helminthic infestation is the most important measure. The present study was conducted to morphological identification of parasitic nematodes and carried out on 300 specimens belonging to two species of the Persian Gulf fishes including: Sphyraena jello and Psettodes erumei which were collected from Bandar Abbasfish market from October to December 2017. The worms were fixed in 70% ethanol, stained and identified. In the present study, S. jello had no helminthic infestation. The species which have been identified in P. erumei were as follows: Anisakis larval type I, Hysterothylacium larval type XV and Hysterothylacium sp.. According to the results, the overall frequency of helminthic infestation was 9.34%, the highest frequency was due to Hysterothylacium larval type XV. Based on the results, there was no helminthic infestation in the flesh of fish. Regarding the zoonotic potential of the identified helminthes, more studies should be done to determinate the helminthic infestation and hazards of zoonotic diseases.
