Many researchers put forward different academic points about this disease，including Vibrio infection，harmful cyanobacteria influence，poisoned by environmental toxin，shrimp stocking biomass overload，viruses and parasitic infections，seed quality deterioration. Based on the disease status，this paper reviewed the latest research progress，and systematically summarized the epidemic situation，pathogen and etiology，detection technique and control measures of the disease， to provide references for further investigating the pathogen and pathogenesis of the disease，and establishing technical solutions of prevention and control.
