Abstract

The helminthes parasites fauna of 313 specimens of Caspian herrings (Clupeonella cultriventris, Clupeonella engrauliformis, Clupeonella grimmi) caught from catching localities situated in southeast of Caspian Sea Were investigated during winter 2008 until autumn 2009. A total of 3 helminthes species were found. They were including Pseudopentagramma symmetrica from intestine (mid gut, hind gut and cecae) Bunocotyle cingulata in intestine, Mazocreas alosae the only monogenean with Marine origin in the gills of infected specimens. In addition to two zoonotic species including Contracecum sp. and Anisakis sp. in digestive system, muscle and ovary and an Acanthocephal, Corynosoma strumosum in intestine which were previously reported. We can conclude that the main characteristic of the helminthes parasites community of Clupeidae species studied is the dominance of the endoparasites species due mainly to the digenean Pseudopentagramma symmetrica and Bunocotyle cingulata and the relative scarcity of ectohelminthes fauna. In this paper the latest data of helminthes fauna and community ecology of digenean of Clupeidae species are presented and the community structure of Pseudopentagramma symmetrica is discussed.
