Abstract:
In 2014, a new syndrome was recognized in redclaw crayfish (Cherax quadricarinatus) from farms in northern Queensland. Crayfish started to die with mortality reaching 40% in approximately three weeks after transportation and translocation stress. In trying to identify the cause of the disease, sequence dependent and independent PCRs failed to identify any aetiology. However, using next gen sequencing of RNA, two novel RNA viruses, namely chequa iflavirus and bunya‐like virus were found in the stressed, dying crayfish.

Early disease investigations in Cherax spp. were observational in nature. Investigators found a variety of pathogens including fungi, ciliates, platyhelminthes, nematodes and viruses. To date, the viral flora identified have been studied using histopathology and transmission electron microscopy. There have been two transmission trials carried out using Cherax spp. infecting viruses, a Reo-like virus and a parvovirus-like virus. Despite multiple detections of viruses in Cherax spp., there has been no molecular characterisation of any of these pathogens. Of the various viral flora identified in

WSSV has caused large economic losses and there is still no adequate treatment. Unlike vertebrate immunity which is composed of both innate and adaptive responses, invertebrates rely on multiple innate defense reactions to combat infections. However, probiotics have been used in aquaculture for the function of immune stimulation. In this study, three probi
