“…Thus, our data suggest that dietary SNSP is more beneficial than INSP in enhancing the fermentation effect of intestinal flora. Similarly, Sinha et al [ 4 ] and our previous studies on largemouth bass [ 8 , 76 ] also found that SNSP had a stronger fermentation-promoting effect compared to INSP. However, unlike in this trial, the enhanced fermentation of dietary SNSP adversely affected the intestinal flora and gut health of largemouth bass [ 8 , 76 ].…”

However, unlike in this trial, the enhanced fermentation of dietary SNSP adversely affected the intestinal flora and gut health of largemouth bass [ 8 , 76 ]. Differences in these results suggest that the effects of fermentation of dietary SNSP on fish gut flora and gut health vary with fish species, which probably correlates with differences in gut physiology.…”

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.

“…The intestinal antioxidant system plays a crucial role in maintaining intestinal health, and it primarily consists of antioxidant enzymes such as SOD, POD, CAT, and GPx. 37 In healthy animals, there is a balance between the production of superoxide radicals and the activity of antioxidants. However, in animals with compromised intestinal health this balance is disrupted, leading to an excess of superoxide radicals and the generation of peroxides such as MDA.…”

“…13,14 Research shows that pectin can enhance the intestinal antioxidant function and intestinal mucosal barrier function in fish. 8,15 Studies conducted on pigs, 10,16 sheep, 17 mice, 18,19 and chickens 20 have also shown that pectin has a positive impact on intestinal health. Therefore, due to its high pectin content, CP may improve the intestinal health of fish.…”

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.

“…A healthy digestive tract is important for maintaining proper immunity and growth in fish, and the health of the digestive tract is regulated by dietary ingredients [ 42 , 43 ]. Oxidative damage is an unavoidable part of the physiological activity of aerobic organisms, due to the continuous production of oxygen radicals during their physiological metabolism [ 44 ]. The scavenging of oxygen radicals is accomplished by the antioxidant system, including antioxidant enzymes and antioxidant active substances [ 45 ].…”

A 56-day feeding trial investigated the effects of dietary histamine on the antioxidant capacity, gastric and intestinal barrier functions, and growth performance of striped catfish (Pangasianodon hypophthalmus). Seven isonitrogenous (34.0% crude protein) and isolipidic (10.5% crude lipid) diets were formulated with supplemental 0, 15, 30, 60, 120, 240, and 480 mg/kg of histamine, named H0, H15, H30, H60, H120, H240, and H480 group, respectively. Results showed that the weight gain rate, specific growth rate, relative intestinal length in the H240 and H480 groups, and the condition factors in the H480 group were significantly lower than those in the H0 group. Intestinal total antioxidant capacity, peroxidase, catalase, superoxide dismutase, glutathione peroxidase, and glutathione reductase activities in the H480 group were significantly lower than those in the H0 group, whereas intestinal malondialdehyde content exhibited the opposite trend. Intestinal complement 3, complement 4, immunoglobulin M, and Recombinant Mucin 2 in the H480 group were significantly lower than those in the H0 group, in contrast to intestinal lipopolysaccharide content. Intestinal IL-10 gene expression in the H480 group was significantly lower than that in the H0 group, whereas the TNF-α, IL-1, IL-6, and IL-8 gene expression exhibited opposite results. Scanning and transmission electron microscopic observation of the gastrointestinal tract revealed severe damage to the gastric mucosa and intestinal epithelium in the H480 group. The abundance of Treponema in the histamine groups was significantly higher than that in the H0 group. These results indicated that high dietary histamine decreases intestinal immunity and antioxidant capacity, inducing digestive tract oxidative damage and ultimately decreasing the growth of striped catfish.
