Abstract: Dropsy was observed in hybrid catfish (a cross between Clarias gariepnus and (Heteobranchus longifilis) fingerlings from African Regional Aquaculture Centre (ARAC), Aluu, Nigeria. It is characterized by swelling of the body of the fish in the ventral region with yellowish watery fluid. Aeromonas hydrophila was recovered from the diseased and dead fish. Pathogenicity of Aeromonas hydrophila isolate was also determined. Clinical manifestation of the disease was observed in the hybrid catfish fingerlings 48 h post inoculation followed by death after 6 days. A. hydrophila was also re-isolated from the experimental fish. Prevention of further spread of the disease was achieved by sanitary measures, disinfection of facilities and environmental control.
