Summary: This study identified 74 volatile compounds in yellow teas, with geraniol being the most abundant aroma compound. Alcohols and esters were the dominant volatiles, accounting for over 50% of total content. 25 key odorants were identified as responsible for the unique aroma quality of yellow tea, with significant differences in content levels observed among different types of yellow teas.

Summary: The study investigated the effects of high-pressure processing on shucked Chinese mitten crab meat and found that the quality of the meat was maintained during superchilled storage for up to 3 weeks, with slight declines in color but stable texture. The combination of HPP shucking and superchilling was effective for preserving the crab meat with slight negative impact on drip loss. These results provide valuable insights for the storage and distribution of HPP-shucked crab meat.

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: 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: Fermentation of aquafeed improves feed quality and enhances the rearing of Eriocheir sinensis. The fermented feed has higher levels of protein, amino acids, and lactic acid, and lower levels of fiber and antinutritional factors compared to non-fermented feed. It is more attractive and stimulating to the crabs, promoting growth, digestive efficiency, and meat flavor. Fermented feed also has a positive impact on antioxidant capacity and the microecological environment in the crab's intestines.

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 preference for shelters varies among different developmental stages of Chinese Mitten Crabs (Eriocheir sinensis). Juvenile crabs prefer grass, button-sized crabs prefer mud, and parent crabs prefer rocks. Light, size, feeding habit, predation, and molting are critical factors that affect shelter preference. These findings contribute to a better understanding of the habits of E. sinensis and provide a reference for resource restoration, habitat construction, and restoration of E. sinensis.

Summary: The study found that thiamethoxam, a neonicotinoid insecticide, can be toxic to crustaceans, leading to hepatotoxicity and neurotoxic effects. The toxicity is related to the activation of antioxidant and detoxification systems, regulation of immune-related gene expression, and potential inflammatory response. High concentrations of thiamethoxam also cause decreased acetylcholinesterase activity and downregulation of synaptic transmission-related genes, affecting neurotoxicity in crustaceans.
