Summary: A novel ssDNA virus, Macrobrachium hepatopancreatic bidnavirus (MHBV), was identified in giant freshwater prawn using metagenomic analysis and de novo assembly. This virus showed circular, eosinophilic inclusions in the nuclei of hepatopancreatic cells. The MHBV genome closely matched the polymerase B gene in the V1 fragment of Bombyx mori bidensovirus 2 (BmBDV2) and belongs to the family Bidnaviridae.

Summary: This study successfully established two CRISPR platforms for the giant freshwater prawn Macrobrachium rosenbergii and achieved high gene editing efficiency through optimization. Editing efficiency was examined and reached as high as 100% in embryos, while the maximum efficiency obtained in primary embryonic cell cultures was 64%. Additionally, a striking difference in deletion patterns around the Cas9 cut site was observed between the two systems, indicating distinct repair mechanisms that require further clarification. The investigation of the Pax6 transcription factor provided a phenotypic proof of concept by showing clear effects on eye development in edited embryos and larvae. This study lays down the foundations for precise functional genomic research and genome editing applications in crustacean species for both aquaculture and sustainable biocontrol, offering opportunities for the creation of selected crustacean lines with distinct attributes.

Summary: This study explored the effects of climate change on the reproductive activity of the monsoon river prawn in the Ganges River basin of Bangladesh. The study found a significant correlation between rainfall and the spawning season, with rainfall impacting the number of ovigerous females and fecundity. The findings suggest that the spawning season of the monsoon river prawn may shift due to climate change.

Summary: This study explored the relationship between gut bacterial community composition and phenotypic traits in different morphotypes of giant freshwater prawn. The results showed that Lactococcus garvieae was the dominant bacterial species and the relative abundance of gut microbiota differed significantly among different morphotypes. Furthermore, there were significant associations between gut microbiota and phenotypic traits.

Summary: This study found that maternal and environmental microbes have significant impacts on the embryonic and larval microbiota of Macrobrachium rosenbergii. The microbial colonization in the embryonic stage was directly related to the maternal prawn's microbiota, while the post-larval stage microbiota was more influenced by the environment.

Summary: This study used a cradle-to-farm Life Cycle Assessment to assess the potential environmental impacts of Macrobrachium rosenbergii farming in Malaysia. The study found that the farming phase had the largest impact on human carcinogenic toxicity and freshwater ecotoxicity. Overall, M. rosenbergii farming was found to have a low environmental impact, but further research on other aspects of sustainability is needed.

Summary: The giant freshwater prawn is a popular tropical species widely cultured across the world with high market demand and attractive prices. Several countries have started selective breeding programmes for this species focused on growth rate, which has resulted in increased edible meat without negative effects on flesh quality attributes. Despite challenges, ongoing research aims to improve productivity in this species.

Summary: This study detected the presence of Covert mortality nodavirus (CMNV) in farmed giant freshwater prawn (Macrobrachium rosenbergii) in Jiangsu, China using TaqMan RT-qPCR. The study identified the intestine, gill, hepatopancreas, and ovary as target organs of CMNV infection in giant freshwater prawn. In addition, the study observed CMNV-like particles in the hepatopancreas and gill tissues. These findings further expand our knowledge on CMNV and provide new insights for investigating the pathogenic factors of giant freshwater prawn disease.

Summary: The study evaluated the impact of gamma radiation on freshwater prawns through electron microscopic studies, revealing structural abnormalities in gills and hepatopancreas with potential effects on respiratory, osmo-ionic regulation, and storage functions. These abnormalities could adversely affect the growth and survivability of Macrobrachium rosenbergii.

Summary: The cytokine Astakine, identified in the freshwater prawn Macrobrachium rosenbergii, plays an important role in promoting the proliferation and differentiation of hematopoietic stem cells and regulating immune responses. Knockdown of MrAst, the homolog of Astakine, increases susceptibility to bacterial and viral infections and affects the functionality and apoptosis of hemocytes.
