Summary: The present study evaluated the effect of potassium diformate (KDF) on the growth performance, digestion and absorption capacity, and intestinal microbes of juvenile grass carp. The results showed that the addition of KDF improved growth performance, intestinal growth and development, and enzyme activity. Furthermore, the addition of KDF up-regulated the expression of AATs, PepT1, and TOR signaling pathway related genes, while altering the abundance of intestinal bacteria. In conclusion, this study provides novel evidence on the positive role and possible mechanisms of KDF in promoting fish growth.

Summary: This study focused on the protective effects of dietary mannoligosaccharides (MOS) supplementation on the intestinal structural integrity of grass carp. The results showed that dietary MOS supplementation protected the microvillus of the intestine, reduced mucosal permeability, and maintained intestinal structural integrity through the inhibition of MLCK and RhoA/ROCK signaling pathways. These findings highlight the positive impact of dietary MOS supplementation on intestinal health.

Summary: This study focused on the involvement of Igf3 in fish reproduction, particularly in grass carp, by isolating the gene and assessing its functions through various experiments. Igf3 was found to regulate gene expression in multiple tissues, affecting growth-related genes and glucose metabolism. This research is the first to reveal the mechanism by which Igf3 regulates the expression of growth-related genes in teleosts.

Summary: Respiratory burst is a process of producing reactive oxygen species in response to pathogens, but excessive production can be harmful. The Keap1-Nrf2-ARE pathway plays a role in alleviating oxidative stress and maintaining cellular homeostasis. The role of Keap1 during bacterial infection in fish is not well understood.

Summary: This study evaluated the effect of dietary rapeseed meal (RM) and hydrolyzable tannin on grass carp and determined the possible role of tannin on health when RM was added to the diet. The findings showed that a certain proportion of RM and tannin induced oxidative stress and intestinal inflammation in grass carp.

Summary: The study found that the supplementation of 600.0 mg/kg nucleotides significantly reduced gill rot morbidity in grass carp induced by F. columnare and enhanced antioxidant enzyme activities and gene expressions, partly through the modulation of Nrf2 signaling. Additionally, it increased antimicrobial substances production and altered inflammatory gene expression profiles, possibly related to NF-kappa B and TOR signaling.

Summary: This study found that the disruption of structural integrity in postmortem fish muscle can affect flesh quality changes. The changes observed in dissolved nucleus, irregular shape of myofibrils, and loose attachment indicate the profound disruption of muscle integrity. The up-regulated gene expressions and decreased antioxidant capacity contribute to the disrupted intercellular integrity and increased oxidative damage.

Summary: The study found that optimal levels of mannan-oligosaccharides (MOS) significantly improved the flesh quality of grass carp, enhancing tenderness, flavor, and reducing cooking loss, while also boosting antioxidant capacity. The mechanisms underlying the improvement in flesh quality by MOS involved reductions in lactate, cathepsin, and oxidative reactions, as well as regulation through NF-E2-related factor 2 (Nrf2) and target of rapamycin (TOR) signaling pathways.
