Abstract

There occurred a large quantity of death of the cultured carp (Cyprinus carpio) in net pens in Lake Taechong and Lake Chungju(Chungcheongbuk-do) from July through Sep., 1987. The carp were two-year-old and 500g to 2,500g in body weight. As a result of biopsy of dying carp, 1 through 10 egg-shaped giant cysts with 12 through 60mm in diameter were observed in their intestine per one carp. The author suggested that the carp were died from blockade of intestinal tract and following enteritis by the giant cysts. The giant cysts were filled with numerous mature Thelohanellus genus spores confirmed to Thelohanellus kitauei after following examination. In this case the author could find out this disease was spread by transverse infection following infestation in net pens of fingerling fish farms.
