Summary: This study found that the addition of 0.05% APS had the best growth-promoting effects on Furong crucian carp, and improved muscle elasticity and chewiness. The 0.15% APS group had the highest spleen-somatic index, and the 0.05% group had the longest intestinal villus length. The addition of 0.05% and 0.10% APS significantly increased antioxidant capacity and decreased MDA content in the fish.

Summary: The effects of beta-CG on mirror carp growth performance and intestinal health were investigated. The results showed that beta-CG did not affect growth performance but induced inflammation in the intestine and altered lipid and protein metabolism. Therefore, fish farmers should process soybean meal to reduce beta-CG concentration before use.

Summary: This study revealed the presence of abundant mucus cells in the intestinal lamina propria of allogeneic crucian carp, with distinct distribution and morphology in different intestinal segments, possibly reflecting the functional differences of these segments. These mucus cells were found to have rudimentary functions such as mucous secretion, phagocytosis, and degradation. Additionally, numerous cells positive for both CD68 and LAMP1 were identified in the intestine, which shared similar distribution and morphology with the mucus cells.

Summary: In this study, it was found that the expression levels of mTOR signaling pathway-related genes were higher in triploid crucian carp compared to diploid red crucian carp. Inhibition of mTOR activity resulted in slower embryonic development and eliminated the expression of mTOR. Conversely, overexpression of the upstream gene AKT2 promoted zebrafish embryonic development.

Summary: Aquatic food is an important source of micronutrients for human beings, and aquaculture plays an increasingly important role in providing this food source. However, bacterial infection poses a severe threat to aquaculture and strategies for managing these infections without antibiotics are lacking. This study investigates the metabolic changes of crucian carp infected with Aeromonas hydrophila and identifies fructose as a crucial biomarker. Supplementation of fructose increases fish survival rate by enhancing the expression of lysozyme and complement 3, leading to reduced bacterial load. These findings demonstrate a metabolism-based approach to manage bacterial infection by modulating the immune response.

Summary: In this study, it was found that feeding crucian carp with feed containing CGA can enhance their growth performance and immunity, regulate intestinal microbial activity, improve antioxidant capacity, and reduce triglyceride content. CGA also promotes the expression of lipid metabolism-related genes in the liver and enhances the relative abundance of beneficial intestinal bacteria. These findings highlight the significance of developing and using CGA as a natural and non-toxic feed additive.

Summary: High stocking density and Cu and trichlorfon exposure induce physiological stress in fish, causing detrimental effects such as inhibition of growth performance and reduced feed intake. This study investigates the protective effects of dietary supplementation with Scoparia dulcis extract on fish under these stressors. The results suggest that dietary supplementation with SDE may be a useful nutritional strategy for relieving the stresses induced by high stocking density and Cu and trichlorfon exposure in fish.

Summary: This study examined the damage to the intestine caused by glycinin and beta-conglycinin, as well as the alleviating effect of alpha-ketoglutarate. The results showed that intake of soybean protein had negative effects on the growth and immune system of fish, while alpha-ketoglutarate could mitigate the damage.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
