“…Likewise, the presence of Shewanella sp. in animals from farm 2 is very interesting result, since different Shewanella species have shown good probiotic properties in farmed fish such as Senegalese sole (Jurado et al, 2018), gilthead seabream (Cordero et al, 2016) and abalone (Jiang et al, 2013). Some preliminary studies have shown that the use of some probiotics can enhance the innate immunity and growth performance of sturgeons (Pourgholam et al, 2016;Fei et al, 2018), but the use of Shewanella species in this fish species has not been investigated to date.This study represents the first application of the Illumina next-generation sequencing (NGS) approach to studying the microbiome of the sturgeon's gut and expands previous knowledge acquired through classical cultivation techniques, PCR-DGGE and pyrosequencing (Akrami et al, 2013;Geraylou et al, 2012;Geraylou et al, 2013a;Geraylou et al, 2013b).…”

The gut microbiota plays a key role in animal health, including immune and metabolic homeostasis. Despite the economic relevance of the sturgeon, studies addressing the gut microbiome of this species are scarce and have focused only on the hindgut. The objective of this work was to use Illumina metabarcoding technology to compare the bacterial microbiomes of two different intestinal locations, the proximal intestine (small intestine) and the distal intestine (hindgut containing the spiral valve), of healthy Siberian sturgeons (Acipenser baerii) reared on two different farms in Spain. Although a high degree of interindividual variability was observed, certain differences between the anatomical parts and between the geographical locations were clear. The results show that the sequences corresponding to the most abundant taxa were the basis for clustering according to anatomical region (proximal and distal intestine), whereas the less abundant taxa were the basis for clustering according to the geographical location of the fish farms. Finally, the results also indicate the existence of certain bacteria that are present in the intestinal tracts of all the fish analyzed in this study; this information may be useful in future studies aiming to establish differences based upon fish health or disease.

“…It can be seen from the culture experiment that S. aquimarina MS4 can improve the growth performance and immune enzyme activity of sea cucumber at low temperature, similar to the activities of other commercial probiotics at room temperature (Gobi et al, 2018; Jurado et al, 2018; Wang et al, 2019). At low water temperatures, sea cucumbers are generally in a state of semihibernation, with reduced food intake and slow weight gain.…”

Probiotics are important biological control products in the aquaculture of sea cucumber, but probiotics used specifically in low‐temperature environments are rare. The present study used treatment with low‐temperature‐resistant Sporosarcina aquimarina MS4 and investigated changes in growth, immunity, intestinal flora and immune‐related gene expression in sea cucumber at low water temperature (8°C). After 60 days of feeding, S. aquimarina MS4 significantly improved growth performance and immune enzyme activity and reduced mortality in sea cucumbers infected with Vibrio splendidus compared with the commercial diet. The intestinal flora structure of the sea cucumbers fed S. aquimarina MS4 differed from that of the control group. Compared with that of the control group, the intestinal flora of sea cucumbers fed S. aquimarina MS4 was always dominated by Proteobacteria and had a higher abundance of Verrucobacteria, and the flora structure was more stable. The expression of the TLR, MyD88, IRAK4, p38 and NFκB genes was upregulated significantly after the addition of S. aquimarina MS4 to the diet. In summary, low‐temperature‐resistant S. aquimarina MS4 could regulate the intestinal flora and immune‐related gene expression of sea cucumber, thereby improving its immunity and resistance to pathogenic bacteria such as V. splendidus.

“…Moreover, IGF-I is an important factor in the somatotrophic axis, having a role as a mediator of the action of GH (growth hormone) on somatic growth regulation. And the IGF-I binds to a membrane receptor IGF-IR (insulin-like growth factor-I receptor) to play its role (Jurado et al 2018). Jurado et al (2018) found that dietary supplementation of probiotic Shewanella putrefaciens Pdp11 upregulated the transcriptions of GH and IGF-IR in Senegalese sole larvae, resulting in an increase in their growth.…”

Recent progress in the understanding of the gut microbiota of marine fishes

As the significance of the gut microbiota has become increasingly realized, a large number of related studies have emerged. With respect to the gut microbial composition of fish, the predominant gut microbes and core gut microbiota have been reported by many researchers. Our understanding of fish gut microbiota, especially its functional roles, has fallen far behind that of terrestrial vertebrates, although previous studies using gnotobiotic zebrafish models have revealed that the gut microbiota performs a significant role in gut development, nutrient metabolism and immune responses. Given that environmental factors of marine habitats are very different from those of freshwater habitats, a distinct difference may exist in the gut microbiota between freshwater and marine fish. Therefore, this review aims to address the advances in marine fish gut microbiota in terms of methodologies, the gut microbial composition, and gnotobiotic models of marine fish, the important factors (host genotype and three environmental factors: temperature, salinity and diet) that drive marine fish gut microbiota, and significant roles of the gut microbiota in marine fish.
