“…NF-E2-related factor 2 (Nrf2) is a key factor in the regulation of gene expression of intestinal antioxidant enzymes in grass carp [ 52 ]. In our previous study, dietary NSPs have been shown to intervene in the intestinal antioxidant system by modulating the Nrf2 signaling pathway [ 7 ]. Also, dietary NSPs exhibited the ability to improve the gut microbiota, SCFAs and antioxidant capacity in an in vitro study [ 53 ].…”

“…Intestinal flora α-diversity is commonly used to assess intestinal flora homeostasis. Our previous studies demonstrated that dietary NSPs have considerable influence on the intestinal flora α-diversity of largemouth bass [ 7 , 8 ] and limited influence on tilapia [ 6 ]. In the present study, changes in the Shannon, Chao1, ACE, and Simpson indices exhibited that dietary NSPs supplementation has no significant effects on the intestinal α-diversity of grass carp.…”

“…NSPs were earlier classified as fiber, a dietary component that is not digested by fish and has limited nutritional value [ 3 , 4 ]. However, recent reports have shown that dietary NSPs have considerable effects on fish, including decreased dietary nutrient utilization and growth, increased intestinal damage and hepatic lesions [ 1 , 2 , 5 , 6 , 7 , 8 ]. Our previous studies have indicated that the physiological impacts of dietary NSPs not only depend on the NSPs contents, but also on the NSPs types (insoluble or soluble) and fish species [ 1 , 6 ].…”

“…Our previous studies have shown that dietary NSPs have a considerable influence on gut microbiota and that it is closely related to fish feeding habits. For example, dietary NSPs inclusion showed no significant impact on the gut microbiota diversity in omnivorous (tilapia) [ 6 ], but significantly altered the gut microbiota diversity of carnivorous fish (largemouth bass) [ 7 ]. The serum metabolome is generally used to evaluate the physiological impact of dietary components on aquatic animals [ 29 , 30 ].…”

Dietary non-starch polysaccharides (NSPs) broadly influence fish intestinal flora and physiological metabolism, but limited information is available on grass carp (Ctenopharyngodon idella). This study investigated the effects of different types of NSPs on the growth, nutrient metabolism status, gut microbiota, and serum metabolome of grass carp. Fish were fed with diets containing 4.4% insoluble NSPs (INSP), 9.24% soluble NSPs (SNSP), 13.64% NSPs (4.4% INSP + 9.24% SNSP, NSP) and non NSPs (FM), respectively, for 9 weeks. Results showed that dietary SNSP decreased protein efficiency ratio and serum protein content, but increased feed coefficient ratio, feed intake, plasma blood urea nitrogen content, and plasma aspartate aminotransferase activity (AST); conversely, dietary INSP decreased plasma AST activity. Dietary INSP and SNSP increased serum free cholesterol content. Dietary NSPs altered the abundance of dominant bacteria and serum metabolite profiles. The differential metabolites between groups were significantly enriched in amino acid synthesis and metabolic pathways. In conclusion, dietary INSP exhibited a growth-promoting effect compared to SNSP. Dietary INSP is beneficial for improving nutrient metabolism and intestinal health. Moreover, dietary NSPs may regulate the physiological metabolism and feeding behavior of grass carp by altering amino acid synthesis and metabolism.

“…Largemouth bass Micropterus salmoides, a typical freshwater carnivorous fish that is widely cultured due to its strong adaptability and fast growth rate (Li et al, 2007;Li et al, 2010;Hu et al, 2019;Liu et al, 2022). In 2019, the cultural production of this species in China reached 477,808 tons (Xu et al, 2022), which generate considerable economic benefits.…”

An 8-week feeding trial was conducted to investigate the effects of different viscous guar gums on the growth performance, apparent nutrient digestibility, intestinal development and morphology of juvenile largemouth bass. Four isoproteic and isolipidic diets (crude protein 42.5%, crude lipid 13.7%) were formulated to contain 8% cellulose (Control group), 8% low viscous guar gum with 2,500 mPa s (Lvs-GG group), 8% medium viscous guar gum with 5,200 mPa s (Mvs-GG group) and 8% high viscous guar gum with 6,000 mPa s (Hvs-GG group), respectively. Each diet was fed to quadruplicate groups of 40 fish (6.00 ± 0.01 g) per repetition. Dietary guar gum inclusion significantly decreased the weight gain rate, specific growth rate, protein efficiency ratio, protein productive value and lipid deposition rate, and these parameters decreased considerably with increasing guar gum viscous and were lowest in the Hvs-GG group. Dietary guar gum inclusion significantly decreased the apparent digestibility of dry matter, crude protein and crude lipid, and these parameters decreased considerably with increasing guar gum viscous and were lowest in the Hvs-GG group. Intestinal protease, lipase and creatine kinase activities in the guar gum groups were significantly lower than those in the control group, and intestinal protease and lipase activities decreased considerably with increased guar gum viscous. Intestinal alkaline phosphatase activity in the Hvs-GG group and intestinal Na+/K+-ATPase activity in the Mvs-GG and Hvs-GG groups were significantly lower than those in the Lvs-GG and control groups. Serum high-density lipoprotein, total cholesterol and triglyceride concentrations and superoxide dismutase activity in the guar gum groups were significantly lower than those in the control group. Intestinal villus height and muscular thickness in the guar gum groups were considerably higher than those in the control group, whereas the goblet cell relative number in the Mvs-GG and Hvs-GG groups and the microvillus height in the Lvs-GG and Hvs-GG groups were significantly lower than those in the control group. The expression level of IGF-1 in the guar gum groups and the expression level of GLP-2 in the Mvs-GG and Hvs-GG groups were significantly higher than those in the control group. These results indicated that guar gum diets adversely affected intestinal morphology, decreased intestinal digestive and absorptive enzyme activities, and caused poor nutrient digestibility and growth performance in juvenile largemouth bass. Moreover, the adverse effects of guar gum are closely related to its viscous, and high viscous guar gum produces more extreme negative impacts on juvenile largemouth bass.

BACKGROUNDCitrus pulp (CP) is rich in pectin, and studies have shown that pectin possesses antioxidant, anti‐inflammatory, and gut microbiota‐regulating properties. However, the application of CP in aquafeed is limited. In this study, the effect of dietary inclusion of CP on the intestinal health of largemouth bass (Micropterus salmoides) was investigated. Juveniles of similar size (6.95 ± 0.07 g) were fed isonitrogenous and isoenergetic diets containing different levels of CP (0%, 3%, 6%, 9%, 12%, or 15%) for 58 days.RESULTSAs the level of CP in the feed for largemouth bass increased, the fish's growth performance and intestinal health initially improved and then declined. Adding low doses of CP (≤9%) to the feed had no significant impact on the growth performance of large‐mouth black bass, whereas high doses of CP (>9%) significantly reduced their growth performance. Adding 6%, 9%, or 12% of CP to that feed enhanced the expression of genes related to tight junctions, anti‐inflammatory activity, anti‐apoptotic activity, and antioxidant activity in the intestines of largemouth bass. It reduced intestinal inflammation and improved intestinal nutrient absorption, intestinal mucosal barrier function, and intestinal antioxidant capacity. Moreover, it improved the α‐diversity, structure, and function of the intestinal flora. The addition of 6% CP had the most beneficial effect on the intestinal health of largemouth bass. On the other hand, the addition of 15% CP had adverse effects on the intestinal antioxidant capacity and intestinal mucosal barrier function of largemouth bass.CONCLUSIONAdding 6–9% CP to the feed for largemouth bass can improve their intestinal health without having a significant impact on their growth performance. CP could serve as a novel prebiotic and immunostimulant ingredient in aquafeed. © 2023 Society of Chemical Industry.
