Summary: This study tracked the succession of gut microbiota in Chinese mitten crabs during their migration from seawater to freshwater. It found that salinity was a major factor affecting the microbiota diversity and community dissimilarity during this transition. The study also revealed that host selection played a dominant role in shaping the microbiota during the freshwater stage. Additionally, the study showed changes in microbial co-occurrence networks and metabolic pathways during the migration process.

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: The study found that thiamethoxam has acute toxic effects on Eriocheir sinensis, reducing their survival rate and impairing their immune and metabolic systems. Higher concentrations of thiamethoxam resulted in a decrease in immune cells and affected enzyme activity and antioxidant capacity in crabs.

Summary: The Chinese mitten crab, a commercially valuable crustacean in China, is facing various diseases affecting its production and trading potential. This study reviews the pathogens associated with the crab since the beginning of its commercial culture, with a focus on those initially discovered in other crustacean species. The findings not only provide recommendations for disease management in the Chinese mitten crab aquaculture sector but also have implications for crustacean cultivation in general.

Summary: The study revealed that 8‰ salinity is the most suitable for juvenile Chinese mitten crabs, while survival rate and immune-related indicators are lower in 0‰ and high salinity conditions. Changes in amino acid and enzyme activity at 8‰ salinity play a key role in the adaptability of E. sinensis to different salinity levels.

Summary: This study investigated the effects of dietary niacin on the growth performance, intestinal histomorphology, body composition, and antioxidant capacity of juvenile Eriocheir sinensis. The results showed that appropriate dietary niacin improved the growth performance and intestinal histomorphology of the crabs, and enhanced their antioxidant capacity.

Summary: Research reveals that starvation leads to a decrease in the hepatopancreas index of Chinese mitten crab, affecting tissue structure, metabolism, and angiogenesis. The AKT signaling pathway plays a crucial role in this process, regulating gene expression related to angiogenesis and apoptosis, ultimately causing hepatopancreas atrophy.

Summary: This study discovered that hemocyanin in crustaceans is allergenic to humans, but there is limited information about its molecular, structural, and allergenic properties. The purified natural protein was identified as Eriocheir sinensis HC by LC-MS/MS, and it showed allergenicity by reacting with serum IgE from crustacean patients. Molecular property analysis revealed that HC is resistant to trypsin digestion, but not heat-stable. Boiling (55.05 ± 3.50%) and steaming (66.84 ± 1.65%) increased β-sheet content and decreased the allergenicity of HC. By comparing the amino acid sequences of eight crustaceans, HC was found to be highly conserved. Five epitopes of HC were identified and validated using a murine sensitization model, with two of them (P3 and P10) matching the predictions from six types of bioinformatics analysis. Combining multiple bioinformatics analyses with a murine sensitization model appears to be an effective method for identifying allergenic epitopes.

Summary: This study investigated the effects of vitamin D-3 on larval Chinese mitten crab, finding that the optimal VD3 requirement for growth performance and molting is 4825-5918 IU/kg. Crabs fed with 6000 IU/kg VD3 showed the highest survival and molting frequency, as well as increased weight gain and antioxidant capacity. Furthermore, VDR was identified as an important regulatory element in molting and innate immunity.

Summary: The growth, development, and reproduction of Chinese mitten crabs are influenced by changes in salinity. Juvenile crabs can survive short-term exposure to saline water within a certain salinity range, but high concentrations of salt can cause tissue damage and reduce their long-term survival rate.

Summary: Photoperiod plays a vital role in the growth, development, and metabolism of crustaceans. The study revealed that the photoperiod affects the gene expression in the hepatopancreas of Chinese mitten crab, leading to changes in immune mechanisms. High-throughput Illumina sequencing was used to explore the genes associated with immune function, and the results demonstrated the impact of photoperiod on gene expression patterns.

Summary: Microbial communities play a critical role in aquaculture ecosystems. This study investigates the influence of sediment nutrient levels on microbial communities in Chinese mitten crab culture ponds. The results show that the diversity and composition of microbial communities vary significantly with different levels of sediment nutrient enrichment. Total nitrogen, organic matter, and pH are identified as important factors driving sediment bacterial community aggregation.

Summary: The study found that moderate acidification has a positive effect on the defense of Chinese mitten crabs against the harmful substance phenanthrene. Phenanthrene significantly inhibits the antioxidant capacity of crabs, but moderate acidification can alleviate this toxic effect.
