Relationship between white spot syndrome virus (WSSV) loads and characterizations of water quality inLitopenaeus vannameiculture ponds during the tropical storm.
Anin-situexperiment was conducted to investigate the effect of tropical storm on the white spot syndrome virus (WSSV) loads inLitopenaeus vannameirearing ponds. White spot syndrome virus loads, heterotrophic bacteria,Vibrioand water quality (including temperature, dissolved oxygen (DO), salinity, pH, NH4-N, and NO2-N) were continually monitored through one tropical storm. The WSSV loads decreased when tropical storm made landfall, and substantially increased when typhoon passed. The variation of WSSV loads was correlated with DO, temperature, heterotrophic bacteria count, and ammonia-N concentrations. These results suggested that maintaining high level DO and promoting heterotrophic bacteria growth in the shrimp ponds might prevent the diseases' outbreak after the landfall of tropical storm.
