Abstract

The grass carp, Ctenopharyngodon idella Val., Collected from Delta Breeding Station Cairo, Egypt was found to be infected with the ciliate parasite Trichophrya piscium. In Fish s 4 grams the parasite caused proliferation of the epithelial lining of the secondary gill lamellae resulting infusion of the lamellae. Blood vessels feeding lamellae became congested resulting in a degeneration of the lamellae epithelium. There was a high incident of mortality among small fish harboring the parasite. Large fish (= 10 grams) were also adversely affected by T. Piscium  although mortality was reduced. Branchial epithelial cells increased in size, blood vessels in the  primary and secondary gill lamellae' became dilated, and there was extensive hyperplasia in the epithelial lining of the primary gill filaments. Short term (30 minutes) treatments with formalin at three concentrations (300,400 and 500 ppm) and copper sulfate at one concentration (20 ppm were unsuccessful in eradicating the parasites from the gills. However, treatment with 5 ppm of formalin over a 4 day period and 1,2 and 5 ppm copper sulfate cleared the parasites form the fish completely within 24 hours period
