  1. aWSSV concentration in suspension is 104 copies/ml
  2. bAverage Rct value of WSSV detection (n = 3)
  3. cWSSV concentration was calculated using the calibration curve (Fig. 3b)
  4. dRecovery was defined as \(\frac{\left\{\mathrm{Concentration by Rct}-{10}^{4}\right\}\mathrm{ copies}/\mathrm{mL}}{{10}^{4} \mathrm{copies}/\mathrm{mL}}\times 100\)
  5. eRecovery error was defined as \( \sqrt {\frac{1}{{n - 1}}\sum\limits_{{k = 1}}^{n} {\left( {x_{i} - \mathop x\limits^{ - } } \right)} ^{2} } \), where \({x}_{i}\) and \(\stackrel{-}{x}\) denote Rct and average Rct values (n = 3), respectively
