Description:
A survey on parasitic infections on Barboid fishes of South- west of Iran (Khouzestan province) were done during Spring 2002 to Autumn 2004. Altogether 296 specimens from 5 different fish species were examined. The fishes were collected from five stations of Karoun River (Ahwaz-Goulestan, Molasani, Dez Dam), Karkheh River (Hamidia Dam) and Shadgan Lagoon. The fishes transported alive to the laboratory where they measured and weighted. Then they were killed by cutting the spinal cord. According to the results of this study 22 different parasites were revealed, 15 of then detected to the species level and 7 of them to the genus level. The metazoans are as follows: The monogenea, are Dactylogyrus onchoratus, D.persicus. Two digeneans: Diplostomum spathaceum, Asymphilodora sp. Five nematods: Rhabdochona denudata, Philometra karuensis, Philometra sp., Psudocapilaria tomentosa Contracecum larvae sp. and only one acanthocephalus, Neoechinorhynchus. Three protozoans are: Ichtyophthirius multifiliis, Trichodina sp., Goussia sp., Balantidium sp. And Myxozoans: Myxobolus persicus M. karuni M. nodulointestinalis, M iranicus, M.mesopotamia, M. pfief eri, Myxobolus sp., Myxidium rhodei, Myxidium pfiefferi. Histopathological investigation of some parasites was done as well. Pathologacal potential of M. nodulointestinalis and M. pfiefferi were revealed. According the results of this study three new parasites and eleven new hosts for Iranian freshwater fishes and three new host for three Myzoxoans were introduced.
