The outbreak of saprolegniasis in the experimental clariid catfish (Clarias batrachus) was observed in the fish diseases laboratory. The spread of this fungal disease was very rapid. The mortality and morbidity were 45% and 90% respectively. The sand goby (Oxyeleotris marmoratus) was considered as the source of disease. The infection disappeared in 9 days after the initial detection of the moribund catfish. The clinical signs, pathological appearance and the characteristics of the causative fungi were described.
