Abstract :
An in-situ experiment was conducted to investigate the effect of tropical storm on the white spot syndrome virus (WSSV) loads
in Litopenaeus vannamei rearing ponds. White spot syndrome virus loads, heterotrophic bacteria, Vibrio and 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.

يك آزمايش مشاهده مستقيم به منظور بررسي اثر طوفان گرمسيري بر بارهاي ويروس سندرم لكه سفيد (WSSV) در استخرهاي پرورش ميگوي پا سفيد غربي ليتوپنائوس وانامي انجام شد. بارهاي WSSV، باكتري هاي هتروفيليك، ويبريو و كيفيت آب (شامل دما، DO، شوري، pH، NH4-N و NO2-N) به صورت مداوم طي يك طوفان گرمسيري مشاهده شدند. بارهاي WSSV موقع ورود طوفان گرمسيري به خشكي كاهش يافتند، و موقع گذر طوفان به طور قابل توجهي افزايش يافتند. تغيير بارهاي WSSV با DO، دما، تعداد باكتري هاي هتروفيليك، و غلظت هاي آمونياك-N مرتبط بود. اين نتايج نشان دادند كه حفظ سطح بالاي DO و افزايش رشد باكتري هاي هتروفيليك در استخرهاي پرورش ميگو ممكن است از وقوع بيماري ها پس از ورود طوفان گرمسيري به خشكي جلوگيري كنند.
