“…PCoA and NMDS results showed that dietary ASTX notably affected the overall structure of intestinal bacterial community in tiger puffer. Different from previous studies addressing the intestinal bacteria of tiger puffer (Chen, Tanaka, Komiya, Itoi, & Sugita, ; Li et al, ; Su et al, ; Sugita, Sugiyama, & Itoi, ; Tanasomwang & Muroga, ), the present study found that Proteobacteria and Tenericutes were the predominant bacterial phyla, and the principal bacterial genera were Arcobacter and Mycoplasma . This difference might be related to fish source, rearing environment and methods for characterizing the intestinal microbiota.…”

A 74‐day feeding trial was conducted to evaluate the effects of dietary astaxanthin (ASTX) on antioxidative status, inflammatory response and microbiota in the intestine of tiger puffer. Four diets differed only in ASTX content, that is, 0 (Control), 50 (ASTX50), 100 (ASTX100) and 500 (ASTX500) mg/kg. Compared with Control, ASTX50 and ASTX100 significantly reduced the malondialdehyde content and spared the activities of antioxidative enzymes in hindgut; however, ASTX500 had higher activity and gene expression of antioxidative enzymes. Nuclear factor‐erythroid 2 p45‐related factor 2 (Nrf2) and Kelch‐like ECH‐associated protein 1 (Keap1) signalling were probably involved in the transcriptional regulation of antioxidative enzymes by dietary ASTX. Compared with Control and ASTX500, ASTX50 and ASTX100 decreased the leucocyte infiltration in the lamina propria of hindgut and down‐regulated the gene expression of tumour necrosis factor‐α (TNF‐α) and interleukin‐8 (IL‐8). ASTX markedly affected the overall structure of intestinal microbiota. The relative abundance of Arcobacter, which has harmful properties, was the lowest in ASTX100 but the highest in ASTX500. In conclusion, dietary ASTX at 50 or 100 mg/kg improved the antioxidative status, alleviated the inflammation and favourably modulated the microbiota in tiger puffer intestine, but excess ASTX exerted contrary effects.

“…This result was consistent with findings reported by Li et al. () using DGGE (2014). Many researchers have found that the dietary feed is one of the important factors influencing digestive tract flora (Einar, Sigmund, Reidar, Stale, & Ashild, ; Haruo et al., ; Moran, Turner, & Clements, ).…”

Summary The present study was conducted to evaluate the effects of different dietary chitosan oligosaccharide (COS) levels on digestive enzyme activity, intestinal bacteria flora, and growth performance of the tiger puffer (Takifugu rubripes). Some 600 fish (initial body weight 129.2 ± 3.1 g) were randomly allocated into twelve 2,000‐L blue cylinder aquaria with 1,500‐L of sea water and divided into four groups (n = 3 aquaria/diet). The fish were fed experimental diets supplemented with different levels of COS (0% [control, L1], 0.05% [LC1], 0.1% [LC2], and 0.2% [LC3]) for 8 weeks. During the experiment, the water temperature was 18 ± 1°C, salinity 28 ± 0.1, pH 8.0 ± 0.1 (mean ± SD, n = 672); airstones were positioned at the bottom of the tank, dissolved oxygen content was above 7.0 mg/L, with a photoperiod of 12 hr light: 12 hr dark. The results showed that dietary COS significantly increased growth performance, intestinal‐somatic index (ISI), and intestinal protease as well as lipase activity (p < .05). However, dietary COS did not have a significant effect on the condition factor (CF), hepatosomatic index (HSI), viscerosomatic index (VSI), survival, or muscle proximate composition of tiger puffers (p > .05). High‐throughput sequencing analysis showed that COS affected the richness and diversity of intestinal microbial species. The Shannon index of intestinal bacterial flora was significantly higher in the control group than in other groups (p < .05). However, dietary COS supplementation did not alter the phyla species of intestinal bacterial flora. There were significantly more Aliivibrio and Bacillus in LC3 than in other groups, and there were significantly fewer Faecalibacterium, Escherichia, and Bacteroides than in other groups at the genus level (p < .05). It can be concluded that dietary COS can improve the growth performance and intestinal digestive enzyme activity and alter the intestinal bacterial flora in the tiger puffer, Takifugu rubripes.

“…It is estimated that trillions of microbes inhabit the gut and perform a variety of functions in animals (Dawood, 2020). In the present study, Proteobacteria was the dominant phylum in the control group, which is consistent with the research results in tiger puffer (Li et al, 2015;Ou et al, 2019;Yu et al, 2019). At the genus level, Vibrio was the dominant genus of juvenile puffer, which was similar to that of Yu et al (2019).…”
