Special Issue Information
Dear Colleagues,
Lipid digestion and fatty acid absorption are vital physiological processes in fish, directly influencing energy metabolism, growth performance, immune function, and product quality. These complex processes are regulated by the interplay of species-specific traits, dietary composition, and environmental conditions. Compared to mammals, fish have evolved diverse and unique adaptive mechanisms over long evolutionary timescales, providing valuable insights into comparative lipid metabolism.
In recent years, the rapid growth of aquaculture has brought a series of emerging challenges: reduced lipid utilization rates caused by plant protein replacing fishmeal in feeds; strategies for the development and application of novel lipid sources; transformation of aquaculture systems from traditional ponds to high-density, industrialized facilities; and the breeding and promotion of new fish varieties. These changes are reshaping conventional perspectives on lipid digestion and absorption in fish, calling for comprehensive research from molecular mechanisms to ecosystem-level regulation.
Advances in molecular biology and multi-omics technologies have provided powerful tools to investigate lipid metabolism, enabling significant breakthroughs in understanding the regulatory mechanisms of key lipid-metabolizing enzymes (e.g., lipase gene families) and fatty acid transport proteins (e.g., FATP4, CD36). However, critical gaps remain regarding fatty acid absorption efficiency, the suitability of alternative lipid sources, effective utilization of functional lipids, and the dynamic regulation of lipid metabolism under varied aquaculture environments.
To promote academic exchange and technological innovation, this Special Issue invites researchers, technical experts, and professionals worldwide to submit original research papers, reviews, and perspectives covering (but not limited to) the following topics:
- Molecular and cellular mechanisms of lipid digestion and fatty acid absorption in fish;
- Regulation and functional characterization of key lipid-metabolizing enzymes and transport proteins;
- Impacts of different feed ingredients and lipid sources on lipid utilization efficiency;
- Absorption efficiency and health benefits of functional fatty acids (e.g., ω-3/ω-6);
- Adaptive changes in lipid metabolism under novel aquaculture systems;
- Multi-omics approaches and bioinformatics in lipid metabolism research;
- Strategies and technological innovations for improving lipid utilization in aquaculture.
We intend that this Special Issue will serve as a comprehensive platform for the latest findings and integrative perspectives in fish lipid metabolism, fostering synergy between theoretical research and practical application. We warmly welcome your contributions and look forward to advancing the frontier of fish lipid digestion and fatty acid absorption studies together.

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. Animals 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 2400 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.
