Association of Aeromonas hydrophila with mortality of catfish (Clarias gariepinus)

Aeromonas hydrophila was the predominant bacteria isolated from moribund fingerlings, post fingerlings, juveniles and table size of Catfish (Clarias gariepinus) cultured in concrete tanks. A. hydrophila was recovered from the internal organs of the fish showing varying degrees of clinical signs of dropsy, ulcers, fin rot and tail rot. The study considers the role of A.hydrophila, a pathogen of emerging importance and its presence in fish as a cause for concern for culturists, processors, consumers and exporters
