Infection Rate of the Shiroud River Fishes with Clinostomum complanatum

Abstract

Due to the variety of fishes and fisheries resources the Shiroud River is considered as one of the most valuable rivers in the west of Mazandaran Province. Therefore the infection rate of the fishes in the river with parasites was examined in Aquatic Disease laboratory of Mazandaran Fisheries Research Center. Among the observed parasitic infections, we will refer to Clinostomum complanatum, which may cause laryngo-pharyngitis in human. The examined fishes were Cobitis taenia, Capoeta capoeta,Neogobius fluviatilis, Carassius auratus, Albumoides bipunctatus, Chalcalburnus chalcoides, Barbus barbus plebejus, Leuciscus cephalus, Alburnus alburnus. Among the mentioned fishes Capoeta capoeta had the highest rate of infection with Clinostomum complanatum. In the research, Alburnoides bipunctatus and Cobitis taenia were introduced as the new hosts of this parasite.
