The causative agent of white tail disease (WTD) in the giant freshwater prawn is Macrobrachium rosenbergii nodavirus (MrNV). recombinant capsid protein (CP) MrNV was previously expressed Escherichia coli, and it self-assembled into icosahedral virus-like particles (VLPs) with a diameter approximately 30 nm. Extensive studies on CP VLPs have attracted widespread attention their potential applica...

Larvae of Macrobrachium rosenbergii (De Man) are photopositive (Ling 1969a.b) and negatively rheotactic. While investigating larval diseases of M, rosenbergii it was observed that weak larvae failed to show both these responses. It was felt that this lack of response could be used to develop a device for separating the weak larvae from the apparently healthy ones. Such a device would be a valua...
