  A look at various intensive shrimp farming systems in Asia

  The impact of diseases led some Asian shrimp farming countries to develop biofloc and recirculation aquaculture system (RAS) production technologies. Treating incoming water for culture operations and wastewater treatment are biosecurity measures for disease prevention and control.

  Double-stranded RNA against WSSV genes provides antiviral protection in shrimp

  Silencing genes in white spot syndrome virus (WSSV) with critical roles in replication could provide a strong antiviral effect and thus reduce shrimp mortality. The authors therefore established a study to evaluate the antiviral efficacy of double-stranded (ds)RNA against non-structural
