The first report of Nematode (Contracaecum) and two Acanthocephala (Serrasentis sagittifer, Tenuiosentis niloticus) in Persian Gulf’s Japanese threadfin bream (Nemipterus japonicus).

In this study, 649 Japanese threadfin bream (Nemipterus japonicus) were captured from the Persian Gulf and necropsied. The helminths of each organ were cleared by clearing solutions and stained by proper staining methods. Identification of the parasites was conducted according to identification keys. Totally, 109 (17%) of fishes were infected with parasites, and infection in intestine was higher than in other organs. In the present study, one Nematode (Contracaecum), two Acanthocephala (Serrasentis sagittifer, Tenuiosentis niloticus), and three larvae were isolated. Although Serrasentis sagittifes was reported in previous studies in Iran, Tenuiosentis niloticus and Contracaecum are reported for first time in Iranian fishes. [ABSTRACT FROM AUTHOR]
