“…Aquatic environments are changeful habitats for many vertebrates, and extensive studies are now going into investigating and cataloging microbial ecology in fish, especially the model organism zebrafish (Bates et al, 2006; Kanther and Rawls, 2010; Stagaman et al, 2017) and some commercial species such as rainbow trout ( Oncorhynchus mykiss ; Lowrey et al, 2015), Atlantic salmon ( Salmo salar ; Green et al, 2013; Gajardo et al, 2016; Schmidt et al, 2016; Zarkasi et al, 2016; Reid et al, 2017), southern catfish ( Silurus meridionalis ; Zhang et al, 2017), and several carps (Hao et al, 2017; Tran et al, 2017). On one hand, different aquatic environments could be associated with radical shifts in feed sources and ecological spectrum for fish; on the other hand, poikilothermic fish respond quickly to external perturbations.…”

“…In addition, hydrological shifts in aquatic environments could result in host microbial divergence (Amato et al, 2013; Bolnick et al, 2014; Kohl and Yahn, 2016; Sylvain et al, 2016), indicating the possibility of restructuring microbial communities in external organs, such as skin and gill. Despite a plethora of studies on internal fish microbiome available (Bolnick et al, 2014; Llewellyn et al, 2014; Lowrey et al, 2015; Sylvain et al, 2016; Zarkasi et al, 2016; Tarnecki et al, 2017; Tran et al, 2017; Zhang et al, 2017), literature is primitive on the knowledge of the external microbiome.…”

Fish are the most widespread aquaculture species and maintain complex associations with microbial consortiums. However, the ecology of these associations present in multiple microhabitats in fish remains elusive, especially on the microbial assembly in fish external (skin and gill) and internal (stomach and intestine) niches, and the relationship with the rearing environment. To understand host dependence and niche differentiation of organ-specific microbiome signatures using a 16S rRNA gene-based sequencing technique, we systematically provided characterizations of a comparative framework relevant to the microbiome of stomach, regional intestine, skin, and gill in two important farmed fish species, herbivorous grass carp (Ctenopharyngodon idella) and carnivorous southern catfish (Silurus meridionalis), and of the rearing water. The different feeding habits of grass carp and southern catfish showed a significant separation of microbial community structure, with great compositional differences across body sites within each species. Site-driven divergences relied on host species: the same types of microhabitats between grass carp and southern catfish harbored differential microbiome. Additionally, body sites had remarkably distinct communities and displayed lower alpha diversity compared to rearing water. Unexpectedly, the stomach of southern catfish had the highest microbial diversity in the digestive tract of the two co-cultured fish species. For external sites within each species, a higher diversity occurred in gill of grass carp and in skin of southern catfish. Our results unveil different topographical microbiome signatures of the co-cultured species, indicating host selection in individual-level microbial assemblages and niche differentiation at the organ scale. This work represents a foundation for understanding the comprehensive microbial ecology of cohabiting farmed fish, suggesting potential applications associated with fish microbiome that urgently needs to be assessed in polycultured operations in aquaculture.

“…Another well‐represented bacteria associated with cestodes inhabiting the gastrointestinal tract of perch were Pseudomonas spp. These bacteria constitute a part of the normal fish microbiota (Sugita, Tsunohara, Ohkoshi, & Deguchi, ; Hansen & Olafsen, ; Al‐Harbi & Uddin, ; Wang et al, ; Wu et al, ; Gajardo et al, ), but there are opportunistic species that may become pathogenic in stressed fish (Ardura, Linde, & Garcia‐Vazquez, ) such as P. fluorescens that causes a red skin disease in grass carp Ctenopharyngodon idellus (Tran, Wang, & Wu, ).…”

Using the approach of sequencing the V3‐V4 region of the 16S rRNA gene, we have analysed the bacterial diversity associated with the distinct compartments of the gastrointestinal tract of perch (Perca fluviatilis) and cestodes (Proteocephalus sp.) parasitizing their digestive tract. The dominant microbiota associated with cestodes (Proteocephalus sp.) was represented by bacteria from the genera Serratia, Pseudomonas and Mycoplasma. By comparing the associated microbiota of perch and cestodes, a clear difference in bacterial composition and diversity was revealed between the community from the stomach content and other parts of the gastrointestinal tract of fish. Microbiota associated with cestodes was not significantly different in comparison with microbiota of different subcompartments of perch (mucosa and content of intestine and pyloric caeca) (ADONIS, p > .05) excluding microbiota of stomach content (ADONIS, p ≤ .05). PICRUSt‐based functional assessments of the microbial communities of perch and cestodes indicated that they mainly linked in terms of metabolism and environmental information processing and could play an important role in the nutrition and health of host.

“…A number of issues come up under culture conditions, including increasing growth performance, digestibility, survival rate, improving immune function as well as maintaining good health of the cultured animals (Hoseinifar et al 2015(Hoseinifar et al , 2016aNawaz et al 2018), all of which require studies to fully understand. Intriguingly, the intestine of aquatic animals is an ideal environment for colonization and proliferation of symbiotic microbes (Han et al 2010;Tran et al 2017;Wang et al 2018). Gut microbiota plays important roles in host health and nutritional metabolism through multiple mechanisms (R ıos-Covi an et al 2016;Li et al 2018a;Ringø et al 2018).…”

Gut microbiota is important and plays a crucial role in the host health and nutritional metabolism through multiple mechanisms. Short‐chain fatty acids (SCFAs), which are carboxylic acids with aliphatic tails < 6 carbons, are mainly produced by anaerobic microbiota through fermentation of carbohydrates in the intestine. Acetate, propionate and butyrate are the most abundant SCFAs metabolites, important in energy homoeostasis, metabolism and the maintenance of gut health. In this review, we describe and document what is known about the production, absorption, transport and receptors as well as the factors that affect SCFA production in aquatic animals. Some evidence on the roles that SCFAs as feed additives play in improving growth performance, digestibility, survival rate, immune responses, disease resistance and structure and function of the intestinal tract and abundance of commensal microbiota in aquatic animals is summarized. In addition, the immune regulatory mechanism of SCFAs is highlighted. Although the effects of SCFAs in aquatic animals have been explored, further research is needed to profoundly investigate the mechanisms that by which SCFAs induce their effects on host metabolism.
