Summary: This study investigated the physiological, transcriptomic, and metabolomic responses after MCRV infection. The results showed that MCRV infection caused changes in enzyme activities, oxidative stress, and tissue damage. Transcriptome analysis identified genes related to detoxification, immune response, and metabolic processes. Two key pathways, phagocytosis and apoptosis, played important roles in response to MCRV infection.

Summary: In this study, a PFK gene from the mud crab Scylla paramamosain, named SpPFK, was cloned and characterized. Knocking down SpPFK using RNA interference significantly reduced lactate dehydrogenase expression after MCDV-1 infection and increased the survival rate of mud crabs. These results suggest that SpPFK plays an important role in the proliferation of MCDV-1 in mud crabs.

Summary: This study examines the diversity and composition of microbial communities in terrestrial mud volcanoes (MVs) and finds that the variation in microbial communities is influenced by distance and physiochemical factors. The results show that microbial communities differ significantly between MVs, but the differences within MVs are relatively small. Physiochemical parameters explain only a small portion of the community variance, with chloride concentration being the most influential factor. Overall, the distribution of microbial communities in terrestrial MVs is affected by multiple factors.

Summary: Environmental gradients may alter the ecological impacts of invasive alien species. In the western Baltic Sea, the functional response of Harris mud crab towards prey was influenced by salinity variation, but there were no significant differences observed across different salinity regimes.

Summary: This study found that water temperature is a key factor affecting the composition of the mud crab gut microbiome, with microbial biodiversity decreasing with higher water temperatures. Salinity, crab mass and carapace width, geographical location, and farming status did not have a significant impact on gut microbiome composition.

Summary: This study comprehensively characterized the hemolymph, hepatopancreas, and intestinal microbiota of Chinese mitten crab using high-throughput sequencing of the 16S rRNA gene. The results showed distinct differences in the structure, composition, and predicted function of the symbiotic microbiota at these sites. The study provides new insights into the taxonomic and functional characteristics of the symbiotic microbiota in crustaceans.

Summary: This study investigated the embryonic development of the mud crab Scylla paramamosain by analyzing three critical parameters: egg color, embryo morphology, and cell division distribution. The findings provide important insights into the embryonic development of the crab and have potential applications in S. paramamosain culture for determining the developmental status and obtaining high-quality seeds.

Summary: During a survey of farmed and wild crustaceans from India, a new spherical baculovirus (MBV) was discovered, known as Penaeus monodon-type baculovirus, which was found for the first time in a crab host. Additionally, some samples showed intranuclear inclusion-like bodies associated with hepatopancreatic viruses.

Summary: This study reports the occurrence of microplastics (MPs) pollution in the mud crab aquaculture system for the first time. The average MPs concentration was found to be 47.5 +/- 11.875 particles/g in sediment and 127.92 +/- 14.99 particles/100 L in water. Fibrous-shaped MPs dominated in all collected samples. The presence of harmful MPs particles in the mud crab aquaculture system highlights the need for further investigation and consideration of farmed mud crabs as an environmentally vulnerable food security concern.

Summary: The study revealed that crab production can be profitable, with crablets, feed, and bamboo fencing being key factors influencing productivity. However, crab fattening faces constraints such as disease infestation, shortage of capital, and insufficient technical knowledge. Providing training and establishing sufficient crablet hatcheries could enhance profitability and resource use efficiency in this farming practice.

Summary: The study investigated the role of sNPF in the immune response of the mud crab Scylla paramamosain. It found that sNPF mediates hemocyte phagocytosis through the sNPF-R receptor-coupled AC-cAMP-PKA pathway, influencing innate immune processes in the crab.
