Endohelminth fauna linked to seasonal changes and host fish size of pike (Esox lucius L.) from Lake Eber,Turkey

In this study,endohelminth parasite fauna of 195 pike (esox lucius l.) specimens from lake eber were investigated. two parasite species were recorded: neascus bravicaudatus (nordmann,1832) in eyes (20%; 2.7±3.1) and acanthocephalus lucii (müller,1776) in intestine of the host fish specimens (9.7%; 1.8±1.2). both of the parasite species are new record for the host fish species in turkey. n. bravicaudatus infection prevalence was highest during winter and spring,and minimum during summer and autumn,with smaller host fish specimens having more parasites than bigger. the other parasite species,a. lucii went through distinct seasonal changes,peaking during the spring with bigger host fishes. copyright 2015 zoological society of pakistan.
