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.Abstract:
The gut microbiome of vertebrates plays an integral role in host health by stimulating development of the immune system, aiding in nutrient acquisition and outcompeting opportunistic pathogens. Development of next-generation sequencing technologies allows researchers to survey complex communities of microorganisms within the microbiome at great depth with minimal costs, resulting in a surge of studies investigating bacterial diversity of fishes. Many of these studies have focused on the microbial structure of economically significant aquaculture species with the goal of manipulating the microbes to increase feed efficiency and decrease disease susceptibility. The unravelling of intricate host-microbe symbioses and identification of core microbiome functions is essential to our ability to use the benefits of a healthy microbiome to our advantage in fish culture, as well as gain deeper understanding of bacterial roles in vertebrate health. 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.read more

Lactic Acid Bacteria in Finfish—An Update
TL;DR: Results indicate that LAB may vary in their immunological effects depending on the species and hosts, which includes their impacts on finfish aquaculture, possible routes for treatment and their interaction with fish immune responses.

TL;DR: The gut microbiota of Atlantic salmon showed similarities with that of mammals and was found in 80% of the samples, and microbial richness and diversity differed significantly and were higher in the digesta than the mucosa.

Evaluation of primers and PCR conditions for the analysis of 16S rRNA genes from a natural environment
TL;DR: This work investigated biases occurring in the polymerase chain reaction (PCR) amplification of 16S rRNA genes from an environmental sample by comparing the clone libraries prepared from the gut homogenate of the termite Reticulitermes speratus, and found that the Bacteria-universal primer, 63F, introduced a seriously biased amplification caused by primer mismatches.

TL;DR: The observed mechanisms that shaped fish gut microbiota seemed to be mainly shaped by the gut environment and by some other selective changes accompanying the host development process, which greatly enhance the understanding of stage-specific community assembly patterns in the fish gut ecosystem.
