Special Issue Information
Dear Colleagues,
Fish nutrition programs play a crucial role in the growth, development, and overall health of fish populations in aquaculture. Epigenetic regulation, on the other hand, involves changes in gene expression that do not involve alterations to the DNA sequence itself but are instead influenced by environmental factors such as nutrition. A well-designed fish nutrition program ensures that fish receive all the essential nutrients required for optimal growth and health. Nutrients such as amino acids, fatty acids, vitamins, and minerals are vital for various physiological processes, including epigenetic regulation. For example, certain nutrients act as cofactors or substrates for enzymes involved in epigenetic modifications, such as DNA methylation and histone acetylation. These nutritional factors provided through fish diets can influence epigenetic mechanisms, affecting gene expression patterns and, consequently, fish phenotype. For instance, certain nutrients may modulate DNA methylation patterns or histone modifications, thereby altering the expression of genes related to growth, immunity, reproduction, and stress response in fish. Furthermore, epigenetic programming during early life stages is particularly sensitive to environmental cues, including nutrition. Early nutrition can have long-lasting effects on the epigenome of fish, influencing their growth trajectory, disease resistance, and reproductive performance later in life. Therefore, optimizing early life nutrition through tailored feeding programs can promote desirable epigenetic modifications and improve overall fish performance. Nutritional strategies aimed at enhancing immune function and stress tolerance can modulate epigenetic pathways involved in immune gene expression and stress response signaling. In summary, fish nutrition programs can exert profound effects on epigenetic regulation, shaping gene expression patterns and phenotypic traits in farmed fish.
The objective of this Topic is to present the most recent advancements in understanding the intricate interplay between fish nutrition and epigenetics. We welcome original research, reviews, and perspective articles describing in vivo, in vitro, and in silico studies. We look forward to receiving your contributions.
Please join us in creating a diverse collection of articles for a variety of topics. We look forward to receiving contributions.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English.
