Special Issue Information

Dear Colleagues,

Ecological succession has been a central theme in ecology for more than 120 years. However, the mechanism underlying gut microbiota succession in aquatic animals remains elusive, especially at a relatively long-term scale (e.g., over host development). Although many studies indicated that both ecological and evolutionary forces could affect the succession of gut microbiota in terrestrial animals, much less is known about that in aquatic fish gut ecosystems. Fish encompass nearly one-half of the vertebrate diversity and are considered the most successful vertebrates evolved on Earth. Their successful evolution may not be possible without the help of gut microbiota. Fish, in turn, provide gut microorganisms with appropriate habitats and necessary nutrients and protect the gut microbiota from adverse disturbances (e.g., pathogen invasion).

Proposed topics for this Special Issue may address the fish gut microbiome and the related environmental microbiome, but are not limited to the following: (1) mechanisms underlying the ecological succession of the fish gut microbiome; (2) ecological service functions of the gut microbiome on host metabolism, disease resistance, etc.; (3) the element cycling is driven by environmental microbiomes and their adaptation mechanisms in aquaculture ecosystems.

All types of manuscripts (original research, review, etc.) are highly welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study focused on monitoring the dynamics of bacterial communities and assessment of the influences of physicochemical parameters during a culture cycle in black carp polyculture ponds. Our results showed high variation in microbial diversity and microbial composition in the water column during the culture period. Proteobacteria, Actinobacteria, and Bacteroidetes were the most abundant phyla, while the abundances of the phyla Cyanobacteria, Firmicutes, and Bacteroidetes changed in different months. Moreover, 13 abundant genera with significant difference were found between different months. Thus, samples in different months were divided into three groups according to principal coordinate analysis (PCoA) and unweighted pair-group method (UPGMA) clustering results. RDA showed that total nitrogen (TN), total phosphorus (TP), phosphate (PO43−-P), nitrate (NO3-N), temperature (T), dissolved oxygen (DO), and pH significantly shaped the microbial community composition in different months. While Pearson correlation coefficient showed that T, SD, and pH were strongly correlated to the dominant genera. Considering some genera are potential pathogenic bacteria, we could manage the black carp pond by quickly monitoring the water temperature and SD in the future. Full article
