The giant river prawn, Macrobrachium rosenbergii, is a major focus of aquaculture in tropical and sub-tropical regions around the globe. Over the last 30 years, culture of M. rosenbergii has increased exponentially as demand has risen both for domestic consumption and for international export trade. As with many aquaculture species increases in production have been accompanied by the emergence of diseases affecting yield, profit and trading potential. Disease-causing agents include pathogens infecting other crustaceans, such as Decapod Iridescent Virus (DIV1), as well as pathogens only known from M. rosenbergii such as White Tail Disease caused by Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV). Here, we review the pathogenic agents associated with the culture of M. rosenbergii since commercial culture began in earnest during the 1970s. Particular emphasis is given to pathogens first identified in other aquaculture host species, but which have subsequently been shown to infect and cause disease in M. rosenbergii. As polyculture of M. rosenbergii with other aquaculture species is common practice, including culture with other decapods, crabs and fish, increased pathogen transfer among these farmed species may occur as M. rosenbergii aquaculture increases in the future.aquaculture, emerging disease, giant river prawn, polyculture | INTRODUCTIONAquaculture is the fastest-growing farmed food sector, with the proportion of cultured to caught seafood increasing year-on-year. 1,2 Global aquaculture production for fish, crustaceans and molluscs surpassed 87 million tonnes in 2020, just under half of all world production. 2 Crustacean production by aquaculture far surpasses that by capture, with more than 11,000,000 tonnes in 2020 from aquaculture compared to 6,000,000 tonnes by capture. 2 Despite these considerable production figures, it is estimated that up to 40% of tropical shrimp aquaculture production is lost annually, 3 equating to losses of over 3 billion USD, and this is primarily due to infection with viral agents. 4 Losses on this scale threaten global food security, with most of the consumption of cultured crustaceans being outside of producing countries, making management and mitigation of disease of key importance to the future success of crustacean aquaculture. 4 Stentiford et al. (2012) outlines a holistic strategy involving both producer and consumer nations to improve husbandry and farm management, better understand pathogens and their spread (either by movement of animals or alternative hosts) and learn lessons from previous disease outbreaks. This review focuses on these points to outline the pathogenic agents in Macrobrachium rosenbergii culture, identify other hosts

Crustaceans are important food sources worldwide and possess significant ecological status in the marine ecosystem. However, our understanding of the diversity and evolution of RNA viruses in crustaceans, especially in economic crustaceans, is still limited. Here, 106 batches of economic crustaceans including 13 species were collected from 24 locations in China during 2016–2021. We identified 90 RNA viruses, 69 of which were divergent from the known viruses. Viral transcripts were assigned to 18 different viral families/clades and three unclassified groups. Among the identified viruses, five were double-stranded RNA viruses, 74 were positive-sense single-stranded RNA (+ssRNA) viruses, nine were negative-sense single-stranded RNA (−ssRNA) viruses, and two belonged to an unclassified RNA virus group. Phylogenetic analyses showed that crustacean viruses were often clustered with viruses identified from invertebrates. Remarkably, most crustacean viruses were closely related to those from different host species along the same food chain or ecological aquatic niche. In addition, the genome structures of the newly discovered picornaviruses exhibited remarkable diversity. Our study significantly expands the diversity of viruses in important economic crustaceans and provides essential data for the risk assessment of the pathogens spreading in the global aquaculture industry. IMPORTANCE The study delves into the largely uncharted territory of RNA viruses in crustaceans, which are not only vital for global food supply but also play a pivotal role in marine ecosystems. Focusing on economic crustaceans, the research uncovers 90 RNA viruses, with 69 being potentially new to science, highlighting the vast unknown viral diversity within these marine organisms. The findings reveal that these viruses are often related to those found in other invertebrates and tend to share close relationships with viruses from species within the same food web or habitat. This suggests that viruses may move between different marine species more frequently than previously thought. The discovery of such a wide variety of viruses, particularly the diverse genome structures of newly identified picornaviruses, is a significant leap forward in understanding the crustacean virology. This knowledge is crucial for managing disease risks in aquaculture and maintaining the balance of marine ecosystems.
