“…Long-term exposure to Lactobacillus plantarum and its metabolic products can significantly improve the immune function and antioxidant ability of T. fulvidraco. Non-specific immune enzyme activity, such as AKP, ACP, and LZM, has been widely used as indices of the immunity of fish in numerous studies [46]. The present results about AKP, ACP, and LZM activities in multiple tissues and organs, including serum, liver, and intestine, confirm that the benefit role of LAB elevated the immunity of T. fulvidraco in the MFLD and SSFD treatments.…”

“…Oxidative stress is harmful to fish; previous studies have shown that the antioxidant defense mechanisms of fish in aquaculture are insufficient, highlighting the need to strengthen the antioxidant system of fish in commercial aquaculture [49]. CAT, SOD, and GSH-Px are important antioxidant enzymes, and these can reduce oxidative stress [24,46]. MDA, a lipid oxidation stress product, is often negatively correlated with antioxidant levels [49].…”

This study aimed to evaluate the effects of solid-state fermented commercial pelleted feed with Lactobacillus plantarum on growth performance, digestive physiology, antioxidant, and immune capacity, as well as morphology and microbiota in intestinal of Tachysurus fulvidraco. A total of 420 fish (49.96 ± 7.10 g) were randomly allocated to twelve 300 L buckets for a 60 d farming trial. The diets of three treatments were established: the untreated commercial diet (UCD), the commercial diet mixed with fermented liquid (MFLD), and the solid-state fermented commercial diet (SSFD). The results indicated that SSFD treatment had a significant positive effect on the growth performance of T. fulvidraco, with an increase of 15.69% to 16.57% (p < 0.05) compared with UCD and MFLD treatments. MFLD and SSFD treatments also showed higher total anti-oxygen capacity, catalase, and glutathione peroxidase activities in the intestine significantly compared with UCD treatment (p < 0.05). Furthermore, the activities of alkaline phosphatase and lysozyme activities both in the liver and intestine were significantly higher in MFLD and SSFD treatments than in UCD treatment (p < 0.05). The villus height in the midintestine was also greater in MFLD and SSFD treatments compared with UCD treatment (p < 0.05). Regarding the intestinal microbiota, the dominant bacteria in UCD treatment was Cetobacterium, with the highest abundance in whole intestinal segments. However, in MFLD and SSFD treatments, the abundance of Cetobacterium in the foreintestine significantly decreased (p < 0.05). In conclusion, this study elucidates that solid-state fermentation feed may not only improve the digestive capacity, antioxidant ability, immune function, and intestinal morphology of T. fulvidraco to enhance growth performance but also influence intestinal microbial composition. These findings provide beneficial proof for developing fermented feed of T. fulvidraco.
