CURRENT FISH DISEASE EPIDEMIC IN THAILAND
PIAMSAK MENASVETA*ABSTRACT: Studies on the pathology, etiology, prophylaxis, and therapy of the current fish disease epidemic in Thailand are reviewed. The origins of the disease are still not entirely clear. However, the abnormally low temperature during the cool months of the year may be an important predisposing cause. Fish under stress by environmental changes usually eat less, become weak and more susceptible to pathogens. Important pathogens identified include virus and the bacteria, Aeromonas hydrophila. Other organisms, such as fungi, protozoa, and ectoparasites are also found to be associated, but are less prominent. The present levels of insecticides and herbicides in natural waters are, however, unlikely to be a predisposing cause of this disease.
