Nutritional Physiology and Environmental Toxicology of Aquatic Animals

Dear Colleagues,

Since the twenty-first century, the important contribution of fisheries and aquaculture sectors to global food security and nutrition has been increasingly recognized. Due to the depletion of fish stocks and the need to protect natural resources, aquaculture has become a significant source of aquatic products. However, the development of the aquaculture industry is constrained by complex environmental ecology and nutrient supply. For example, toxicity of chemicals, hazards, radiation, and environmental stressors causes great harm to the growth, health, and quality of aquatic animals. Inadequate nutrient intake or the irrational application of ingredients in feed can also pose a significant threat to the growth, health, and quality of aquatic animals.

Global climate change, industrial development, and human activities have caused a series of environmental problems, emphasizing the urgency of fisheries and aquaculture to adapt to complex environments. Under intensive culture conditions, the relationships between the nutrition, environment, and metabolism of fish have also changed. The availability and quality of food sources in aquatic environments influence the nutritional status of aquatic animals, which in turn affects the metabolic processes and energy utilization of fish. Meanwhile, environmental factors such as temperature, oxygen levels, and water quality can directly influence the metabolic processes of aquatic animals. Therefore, it is essential to investigate the nutritional physiology of aquatic animals and assess the impact of environmental toxicology to promote green farming and achieve sustainable development.

Topics of interest mainly include, but are not limited to, the following (including original research articles, reviews, and communications):

• The nutritional impact of proteins, lipids, carbohydrates, and minerals on aquatic animals;
• The physiological and metabolic effects of nutrient supplementation;
• The limitations of alternatives to fish-meal raw materials as ingredients in aquatic feeds and respective mitigation strategies;
• The development of new feed sources, such as new feed ingredients and feed additives;
• Physiological responses to the exposure to pollutants/toxins;
• Toxic residues and food safety considerations.

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. 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.
