【 摘 要 】

Catfish (Clarias gariepinus) is one of the familiar freshwater fish cultured in Indonesia farmer. One of the reason is the high mortality of the catfish infected by Aeromonas hydrophila and Saprolegnia sp. Motile Aeromonas septicemia (MAS) is a common bacterial disease, caused by Aeromonas hydrophila, which affects freshwater fish. In Southeast Asia, the outbreak of this disease was firstly reported from West Java in 1980, when a total of 82.5 tons a month of catfish were lost, while in Central Java in 1984, the total loss was 1.6 tons. Saprolegniosis can cause economic loss due to high mortality from its case reaching 10% to 50%. This research aimed to identify and determine the percentage of A. hydrophila and Saprolegnia sp. The catfish farmed in bozem Moro Krembangan, Surabaya, East Java. Meanwhile, a supporting parameter in this research is the value of water quality parameter including pH, temperature, ammonia and dissolved oxygen that were measured during sampling. The results showed that of the 20 samples taken from the two cages, 19 fish were positively infected by A. drophila. percentage of infections of A. hydrophila that infect umbo catfish in Moro Krembangan, was 95%, while the percentage Saprolegnia sp. was 90%.
