abstract
Tilapia is considered as a significant group of fish as it serves as a cheap protein source and livelihood for people. Recently, the significant mortality of wild and cultured tilapia has been observed in two continents. The etiological agent behind these outbreaks, a novel RNA virus (Tilapia lake virus) was described here and its pathogenesis and diagnosis have been revealed. This article creates awareness among the tilapia farmers to perform good aquaculture practices to prevent the catastrophic losses and also to control the spread of this deadly virus worldwide.
