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

On-site diagnostic kit identifies WSSV in shrimp

Loop mediated isothermal amplification (LAMP) is a highly specific technique that can amplify DNA in isothermal conditions. The kit can amplify the target gene of the pathogen using a single temperature and give results in one hour.
