Clinostomum complanatum (Trematoda) infection in freshwater fish from fish dealers in Tottori, Japan.

Abstract

During the period January 1989 through February 1991, 327 freshwater fish of 3 different species (Carassius cuvieri, Cobitis anguillicaudatus and Hypomesus transpacificus) purchased from 7 fish dealers in Tottori City were investigated for the metacercarial infection of Clinostomum complanatum. Among them, 20.5% (16/78) of C. cuvieri were infected with this fluke. Each infected fish harbored 1 to 30 metacercariae. The sites and rates of parasitization of metacercariae in the infected fish were 42.4% in the body muscles, 30.3% in the muscles at the pectoral fin, 21.2% in the tissues around the gills and 6.1% in the cheek muscles.
