Abstract:
Objective: The present study was aimed to evaluate the impact of Phytocee™ (PHY) on survivability of Litopenaeus vannamei shrimp challenged with white spot syndrome virus (WSSV) and salinity shock stress (SSS).
Methods: In experiment 1, shrimps were distributed into two groups viz AAM500 (AAM, ascorbic acid monophosphate) and AAM500+PHY500, and its impact on survival rate in normal shrimps without any challenge was recorded. In experiment 2, four groups viz AAM500, AAM500+PHY1000, AAM250 and AAM250+PHY1000 were subjected to WSSV challenge after 28 days of feeding. In experiment 3, two groups viz AAM500 and AAM500+PHY1000 were exposed to SSS after 42 days. The mortality (%) and median lethal time (MLT) were recorded in experiment 2 and 3.
Results: PHY500 produced a better survivability in normal shrimps, and PHY1000 displayed a lesser mortality (%) and higher MLT in shrimps challenged with WSSV and SSS.
Conclusions: This study demonstrated the adaptogenic potential and anti-stress activity of Phytocee ™, hence it could be recommended to use safely in shrimps for better disease resistance and survivability.
