Special Issue Information
Dear Colleagues,
The intricate interplay between diet and intestinal microbiota in fish is a rapidly evolving field with profound implications for aquaculture productivity, ecological sustainability, and aquatic animal health. This Special Issue of Fishes will explore the dynamic relationships between dietary components, microbial communities, and host physiology in fish, emphasizing their roles in nutrient metabolism, immune regulation, and disease resistance. As aquaculture intensifies globally, understanding how diet shapes gut microbiota composition and function, and vice versa, is critical for optimizing feed efficiency and reducing environmental impacts. This Special Issue, “Diet and Intestinal Microbiota of Fish”, will address gaps in current research by integrating studies on species-specific microbiota adaptations, dietary interventions (e.g., probiotics, prebiotics), and ecological interactions within aquatic environments. Topics may include, but are not limited to, the following:
- Dietary modulation of gut microbiota diversity and stability, such as the effects of fishmeal alternatives or carbohydrate utilization mediated by key taxa including Cetobacterium;
- Host–microbe metabolic cross-talk, including microbial contributions to lipid, carbohydrate, and amino acid metabolism;
- Impacts of environmental stressors on diet-microbiota–host interactions;
- Microbial biomarkers for health and disease, particularly in the context of antibiotic resistance and pathogen colonization;
- Innovative methodologies, such as metagenomics and machine learning, to decode microbial community dynamics and functional pathways.

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. Fishes is an international peer-reviewed open access monthly 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.
