“…As a cost-effective and sustainable alternative to fish meal, various plant proteins are used to partially or entirely replace fish meal. However, an inappropriate plant protein substitution ratio could adversely affect aquatic animals’ growth due to limiting amino acids and anti-nutritional factors ( 6 , 22 ). Using probiotic bacteria to alleviate the adverse effects of growth suppression in aquatic animals induced by plant protein substitution is becoming an effective auxiliary strategy ( 23 ).…”

The unsuitable substitution ratio of fish meal by plant protein will reshape the intestinal microbial composition and intestine immunity. However, previous studies were mostly limited to investigating how different feed or probiotics characterized the microbial composition but ignored the biological interactions between bacteria and host physiology through secondary metabolites. Therefore, this study integrates the apparent indicators monitoring, 16S rDNA sequencing, and metabonomics to systematically investigate the effects of cottonseed protein concentrate (CPC) substitution of fish meal and Bacillus coagulans intervention on gut microbes, secondary metabolites, and intestinal immunity of Macrobrachium rosenbergii. Prawns were fed with three diets for 70 days: HF diets contained 25% fish meal, CPC in LF diets were replaced with 10% fish meal, and LF diets supplemented with 2 × 108 CFU/g diet B. coagulans were designated as BC diets. Results showed that CPC substitution induced a significant decrease in digestive enzyme activities (trypsin and lipase) and gut barrier protein PT-1 expression and a significant increase in γ-GT enzyme activity and inflammatory-related factors (Relish and Toll) expression. B. coagulans treatment mitigated the negative changes of the above indicators. Meanwhile, it significantly improved the expression levels of the barrier factor PT-1, the reparative cytokine IL-22, and Cu/Zn-SOD. CPC substitution resulted in a remarkable downregulated abundance of Firmicutes phyla, Flavobacterium spp., and Bacillus spp. B. coagulans treatment induced the callback of Firmicutes abundance and improved the relative abundance of Sphingomonas, Bacillus, and Ralstonia. Functional prediction indicated that CPC substitution resulted in elevated potential pathogenicity of microbial flora, and B. coagulans reduces the pathogenesis risk. Pearson’s correlation analysis established a significant positive correlation between differential genera (Sphingomonas, Bacillus, and Ralstonia) and secondary metabolites (including sphingosine, dehydrophytosphingosine, amino acid metabolites, etc.). Meanwhile, the latter were significantly associated with intestinal immunoregulation-related genes (Cu/Zn-SOD, IL-22, PT-1, Toll, and Relish). This study indicated that B. coagulans could mediate specific gut microbes and the combined action of multiple functional secondary metabolites to affect intestinal barrier function, digestion, and inflammation. Our study revealed the decisive role of gut microbes and derived secondary metabolites in the model of dietary composition-induced intestinal injury and probiotic treatment from a new perspective.

“…The Nile tilapia is a widely cultivated species of freshwater fish in over 120 countries worldwide. The GIFT (Genetic Improvement of Farmed Tilapia) strain was a genetically modified tilapia strain, created by crossing Nile tilapia from eight different regions [30]. The popularity of tilapia can be attributed to its muscle quality and nutritional value, which are impacted by the fatty acid composition [31].…”

To reduce the negative impact of fish oil substitutes on the fatty acid composition of farmed fish, this experiment utilized different types of oils as dietary lipid sources for GIFT tilapia. Tilapia oil (FO) was used as the control, along with corn oil (CO), linseed oil (LO), algae oil (AO), and a mixture of linseed oil and algae oil in various ratios of 1 : 2, 1 : 1, and 2 : 1 (LA12, LA11, and LA21) to reshape the fatty acid profile of GIFT tilapia (0.205 ± 0.005 g) in the muscle. The weight gain and specific growth rate of tilapia in the LO and control groups were significantly higher than in other treatments (P<0.05). Meanwhile, despite the AO group exhibited the highest docosahexaenoic acid (DHA) content (P<0.05), it also exhibited the highest levels of malondialdehyde content and superoxide dismutase activity (P<0.05). The mRNA expression levels of Δ6/Δ5 fatty acyl desaturase 2 (Δ6/Δ5FADs2), Δ4 fatty acyl desaturase 2 (Δ4FADs2), acetyl-CoA carboxylase α (ACCα), and elongase of very long chain fatty acids 5 (ELOVL5) in the hepatopancreas of LO group were exhibited a significant upregulation compared to the control (P<0.05). The synthesis of DHA and eicosapentaenoic acid (EPA) in the muscles of LA12, LA11, and LA21 groups increased as the proportion of DHA decreased in the diets. In conclusion, the edible value of fatty acids of tilapia muscle, especially n-3 long-chain polyunsaturated fatty acids, can be significantly improved by adjusting the oil source in the diet through lipid metabolism.

“…Tilapia (Oreochromis niloticus) commodity is one of the global aquaculture commodities [1], and is also a potential commodity to be developed because it is easy to cultivate, selling power and market prices are stable [2]. The advantages of tilapia cultivation were also conveyed by [3] that this fish is easy to cultivate because it is resistant to climate change, then grows fast and is resistant to disease [4].…”

The combination of commercial feed and fermented bran is an alternative to reduce production costs from aquaculture activities. The purpose of this study was to analyze the growth and survival of tilapia by reducing the frequency of feeding commercially replaced with fermented bran. This research was conducted from January 2022 to February 2022 at the Ujung Batee Brackish Water Cultivation Center, Mesjid Raya, Aceh Besar. This research method used a completely randomized design (CRD) with five treatments and three repetitions, namely treatment A (5% commercial feed without fermented bran), treatment B (4% commercial feed and 1% fermented bran), treatment C (3% commercial feed and 2% fermented bran), treatment D (2% commercial feed and 3% fermented bran), treatment E (1% commercial feed and 4% fermented bran). Based on the results of research that has been analyzed by ANOVA test shows that the combination of commercial feed and fermented bran to fish has an effect on growth, but does not affect the survival rate of fish.
