Article Abstract
Eating disorders are directly or indirectly influenced by gut microbiota and innate immunity. Probiotics have been shown to regulate gut microbiota and stimulate immunity in a variety of species. In this study, three kinds of probiotics, namely, , and , were selected for the experiment. The results showed that the addition of three probiotics at a concentration of 10 colony forming unit/mL to the culture water significantly increased the ratio of the pellet feed recipients and survival rate of mandarin fish () under pellet-feed feeding. In addition, the three kinds of probiotics reversed the decrease in serum lysozyme and immunoglobulin M content, the decrease in the activity of antioxidant enzymes glutathione and catalase and the decrease in the expression of the appetite-stimulating regulator agouti gene-related protein of mandarin fish caused by pellet-feed feeding. In terms of intestinal health, the three probiotics reduced the abundance of pathogenic bacteria in the gut microbiota and increased the height of intestinal villi and the thickness of foregut basement membrane of mandarin fish under pellet-feed feeding. In general, the addition of the three probiotics can significantly improve eating disorders of mandarin fish caused by pellet feeding.

A complex microbial community gives the possibility to produce biogenic amines in traditional fermented foods. In this study, the metabolism mechanisms of biogenic amines during fermentation of fermented mandarin fish were revealed based on the metabolic pathways and correlation analysis. Functional genes based on KEGG orthology related to biogenic amine metabolism were selected from the metagenome and were used to construct the biogenic amine metabolic pathways in .

The skin mucosa of fish serves as a vital immune barrier, offering both anatomical and physiological protection against external pathogens. This study explored gene expression profiles and potential immune signaling pathways in the skin of mandarin fish (Siniperca chuatsi) following stimulation with LPS or poly (I:C) at 0 h, 3 h, 6 h, and 12 h. Results revealed 648 shared differentially expressed genes (DEGs) across LPS treatment groups and 484 shared DEGs under poly (I:C) treatment.

Infectious spleen and kidney necrosis virus (ISKNV), the type species of genus Megalocytivirus within Iridoviridae family, stands as a leading causative agent of viral diseases in diverse teleost fish globally. Previous study has demonstrated that lymphatic endothelial cells exhibit specific adhesion to virus-mock basement membranes (VMBMs) formed outside ISKNV-infected cells, underscoring the critical role of this interaction in the ISKNV infection process. However, the lack of a dedicated endothelial cell line has significantly hindered in vitro investigations into ISKNV pathogenesis.

A 56-day trial was conducted to assess the effects of rice straw (RS) and bamboo flour (BF) on growth performance, water quality, gill histology, and the bacterial community of water and the intestine of mandarin fish () in biofloc technology systems. The results showed that mandarin fish in the RS and BF groups had comparable survival rates of 100.00 ± 0.

Mandarin fish ranavirus (MRV) has caused substantial economic losses in the culture of mandarin fish (Siniperca chuatsi) in China. The pathogenesis of MRV infection is largely attributed to the systemic hyperinflammation. However, the roles of specific signaling pathways and their activation in driving the excessive triggering of pro-inflammatory mediators during MRV infection remain inadequately understood.
