ABSTRACT Gut microbiota influence the development and physiology of their animal hosts, and these effects are determined in part by the composition of these microbial communities. Gut microbiota composition can be affected by introduction of microbes from the environment, changes in the gut habitat during development, and acute dietary alterations. However, little is known about the relationship between gut and environmental microbiotas or about how host development and dietary differences… 
The Function and the Affecting Factors of the Zebrafish Gut Microbiota
TLDR
In this review, a large amount of data focusing on the close relationship between gut microbiota and host health is reviewed and the functions of gut microbiota in regulating intestinal epithelial cell differentiation, intestinal epithelium cell proliferation, metabolic function, and immune response are outlined.
Host Age Affects the Development of Southern Catfish Gut Bacterial Community Divergent From That in the Food and Rearing Water
TLDR
Results showed that gut microbial diversity in southern catfish tended to increase linearly as host aged, indicating that host development fundamentally shapes a key transition in microbial community structure, which is independent of dietary effects.
High-Fat Diet Consumption Induces Microbiota Dysbiosis and Intestinal Inflammation in Zebrafish
TLDR
This is the first study performed in zebrafish which suggests that the consumption of a diet enriched with 10% fat changes the intestinal microbial community composition, which was correlated with low-grade inflammation.
The role of adaptive immunity as an ecological filter on the gut microbiota in zebrafish
TLDR
The results suggest that adaptive immunity has a role as an ecological filter of the zebrafish gut microbiota, but it can be overwhelmed by other factors, including transmission of microbes among hosts.
Host development overwhelms environmental dispersal in governing the ecological succession of zebrafish gut microbiota
TLDR
It is found that zebrafish developmental stage substantially explains the gut microbial community succession, whereas the environmental effects do not significantly affect the gut microbiota succession from larvae to adult fish.
Research Progress of the Gut Microbiome in Hybrid Fish
TLDR
The role of the gut microbiome in the speciation and ecological invasion of hybrid fish is summarized and the potential interaction with environmental microbiomes is discussed, including the implications for population expansion, fish conservation and management.
Commensal Microbiota Regulate Vertebrate Innate Immunity-Insights From the Zebrafish
TLDR
Key insights afforded by the zebrafish into the impact of microbiota on innate immunity are reviewed, including evidence that the perception of and response to the microbiota is evolutionarily conserved.
Simple animal models for microbiome research
TLDR
The opportunity for microbiome research on the traditional biomedical models zebrafish, Drosophila melanogaster and Caenorhabditis elegans, which command superb research resources and tools, is discussed and simple animal models are emerging as valuable tools for microbiomeResearch.
Fish intestinal microbiome: diversity and symbiosis unravelled by metagenomics
TLDR
This review aims to summarize the available knowledge on fish gastrointestinal communities obtained from metagenomics, including biases from sample processing, factors influencing assemblage structure, intestinal microbiology of important aquaculture species and description of the teleostean core microbiome.
Effects of aging on the skin and gill microbiota of farmed seabass and seabream
TLDR
Important microbial differences in composition and potential functionality across different ages of farmed seabass and seabream may be related to somatic growth and the onset of sexual maturation, which could enhance the fish coping mechanisms during stressful conditions.

The composition of the zebrafish intestinal microbial community varies across development
TLDR
The results indicate that zebrafish intestinal microbiota assemble into distinct communities throughout development, and that these communities are increasingly different from the surrounding environment and from one another.
Evidence for a core gut microbiota in the zebrafish
TLDR
Gut microbiota membership in domesticated and recently caught zebrafish was strikingly similar, with a shared core gut microbiota, and the zebra fish intestinal habitat selects for specific bacterial taxa despite radical differences in host provenance and domestication status.
Microbiota regulate intestinal absorption and metabolism of fatty acids in the zebrafish.
Gnotobiotic zebrafish reveal evolutionarily conserved responses to the gut microbiota.
TLDR
Methods for producing and rearing germ-free zebrafish through late juvenile stages are developed and established as a useful model for dissecting the molecular foundations of host-microbial interactions in the vertebrate digestive tract.
Structural resilience of the gut microbiota in adult mice under high-fat dietary perturbations
TLDR
It is suggested that HFD-induced structural changes of the Gut microbiota can be attributed to reversible elevation or diminution of specific phylotypes, indicating the significant structural resilience of the gut microbiota of adult mice to dietary perturbations.
Complex interactions among diet, gastrointestinal transit, and gut microbiota in humanized mice.
TLDR
Diet can affect GI transit through microbiota-dependent or microbiota-independent pathways, depending on the type of dietary change, and the effect of the microbiota on transit largely depends on the amount and type of polysaccharides present in the diet.
Antibiotics in early life alter the murine colonic microbiome and adiposity
TLDR
A model of adiposity is generated by giving subtherapeutic antibiotic therapy to young mice and changes in the composition and capabilities of the gut microbiome are evaluated, demonstrating the alteration of early-life murine metabolic homeostasis through antibiotic manipulation.
Succession of microbial consortia in the developing infant gut microbiome
TLDR
This study revealed that seemingly chaotic shifts in the microbiome are associated with life events; however, additional experiments ought to be conducted to assess how different infants respond to similar life events.
