Nutrient Metabolism and Intestinal Health Studies in Aquatic Animals

Dear Colleagues,

As aquaculture has continued to expand greatly in global distribution and in the yield of aquatic products, the demand for fish meal and oil has increased; however, the supply is limited, making the substitution of these dietary components with high-level vegetable oil, high-level plant protein, high-lipid and high-carbohydrate diets an imperative alternative. However, these alternative diets also damage the Nutrient Metabolism and Intestinal Health in Aquatic Animals by inducing decreased growth performance, reduced immunity and stress tolerance, abnormal liver lipid deposition, and intestinal dysfunction, usually accompanied by dysbiosis of intestinal microbiota, lower meat quality, cellular dysfunction, etc., as well as consequent restrictions on the sustainable development of aquaculture. There is a body of evidence suggesting that dietary feed additives are an effective strategy to improve the nutrient metabolism and health of aquatic animals, whereas the underlying mechanisms are still unclear. Therefore, it is necessary for aquatic nutritionists to clarify the mechanisms of diet-induced and intestinal dysfunction and metabolic disorders, and to seek suitable therapies to alleviate the harmful symptoms.

This Special Issue of Metabolites welcomes the submission of original research articles and reviews analyzing rigorously peer-reviewed studies, with scopes including but not limited to the following: 1) investigating the deep mechanisms of these diets and their relationship to liver injury and intestinal function; 2) searching for effective nutritional, endocrinological and molecular regulation strategies in nutrient metabolism and intestinal health to help solve these problems; and 3) using new detection tools and novel data analysis tools for targeted and untargeted metabonomics analysis in aquaculture nutrition and physiology.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites 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 2700 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.
