A survey of digestive system'sparasites of the Klunzinger's Mullet (Liza klunzingri) in coastal waters of BandarAbbass

The present study was to investigate the ecology of fish parasites Liza klunzingeri (Day, 1888) for a period of 9 months from may to jaunary 2013 in the coastal of bandarabbass was performed.

From the total samples, 46 samples were infected by one or more species of parasites (prevalence of 90%) and the mean frequency of moderate parasite for Liza klunzingeri equal to 22.72 and 25.19 against the parasite. Analysis of the data showed that the prevalence of parasites in different months is significant. The most common parasites parasite abundance n.zabensis in January and Haploporinae in October, respectively.
