摘要

Whether clinical white spots in shrimp appear only because of white spot disease (WSD) is a question needed to be asked in the light of new causes for development of white spots. The answer is 'no'. In fact, white spots could be due to WSD caused by white spot syndrome virus (WSSV) or bacterial disease or high water pH. Most shrimp farmers rely on white spots in the exoskeleton of shrimp as the specific diagnosis for the most dreaded WSD and resort to emergency harvest without knowing the actual cause. Against this background, the mechanism and possibilities of formation of white spots in shrimp is discussed, which would help farmers and the shrimp farming industry in understanding the white spots better and in proper decision making for emergency harvest. Differential diagnosis of the disease by histopathology, polymerase chain reaction (PCR) and immunodot test is therefore essential..
