Environmental Stress and Toxicology in Aquaculture: A Molecular Perspective

Dear Colleagues,

Aquaculture is a vital component of global food security and the fastest-growing food production sector. However, the sustainability of aquaculture is increasingly challenged by aquatic environmental pollution and rapid climate change. Understanding how aquatic organisms (including fish, crustaceans, and mollusks) respond to environmental stressors and toxicants at the molecular level is crucial for improving animal health and production efficiency. This research area bridges the gap between environmental chemistry and organismal physiology, offering insights into the adaptive mechanisms of aquatic species.

This Special Issue aims to collect the latest advances in the molecular physiology and toxicology of aquatic animals. We seek to elucidate the molecular mechanisms underlying physiological responses to various stressors, including heavy metals, pesticides, microplastics, and emerging contaminants. By integrating molecular tools (such as omics technologies) with physiological assessments, this collection will deepen our understanding of toxicity pathways, detoxification mechanisms, and stress adaptation strategies in aquaculture species.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Molecular mechanisms of toxicity and detoxification in aquatic animals.
• Physiological and molecular responses to environmental pollutants (e.g., heavy metals, pesticides, antibiotics).
• Oxidative stress, immune response, and apoptosis pathways induced by toxicants.
• Application of multi-omics (transcriptomics, proteomics, metabolomics) in aquatic toxicology.
• Molecular basis of adaptation to environmental stress (hypoxia, temperature, salinity) in aquaculture.
• Impact of waterborne or dietary toxins on growth, reproduction, and development.

We look forward to receiving your contributions.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Current Issues in Molecular Biology 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 2200 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.
