Ichthyophonus disease had broken out among rock bream in Dec. 1989. Diseased-fish showed markedly stunted growth and darkish coloration, and anatomically the liver with small white nodules, tumefied spleen with its granulous surface, and the markedly tumefied kidney. Microscopic examination of liver, kidney, spleen and gill from 10 rock bream revealed cyst of the fungus Ichthyophonus sp. Rock bream were heavily infected with the highest concentrations of spherical multinucleate bodies in the liver, the spleen, the kidney and the gills. In heavily infected sectors of tissue a common necrotic zone was formed around spore aggregates. Spherical multinucleate hyphal terminal bodies developed thin hyphae longer than 1mm which divided into many branches.
