Special Issue Information

Dear Colleagues,

As the world aquaculture industry enters its maturity stage, some culture systems, especially intensive systems, fail due to a lack of resources or difficulty in controlling and optimizing rearing conditions. Meanwhile, cultured organisms are in constant biotic and abiotic stress, which affect antioxidant and detoxification responses, and significantly affect zootechnical parameters, such as growth and survival.

Stressing conditions in culture ponds may lead to disrupting homeostasis and causing oxidative stress in organisms. Reactive oxygen species (ROS) in excess can lead to the oxidation of cell membranes, as well as lesions in mitochondria, proteins, DNA, and other cell components.

Medicinal plants, organic and inorganic compounds, microorganisms, and other products are able to improve the antioxidant defense system, helping to prevent and repair oxidative damage, thus enhancing immune responses and general health status. The success of these products in reared organisms depends on factors such as administration ways, doses, genetics, age stadium, culture conditions, and others.

Improving antioxidant response, reared organisms may increase tolerance against biotic and abiotic stressors such as stocking density, salinity, temperature, pathogens, marine toxins, heavy metals, and others.

This Special Issue will publish original research papers and reviews on aspects of antioxidants benefits in aquaculture that relate to the following topics:

  • Dietary antioxidants and food supplements;
  • Screening of antioxidant products for biological activities;
  • Antioxidant potential of live microorganisms or their components;
  • Antioxidant products in intestinal health;
  • Understanding the pathways of redox homeostasis;
  • The relationship between antioxidants and host health;
  • Antioxidant response against biotic or abiotic stressors.

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 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. Antioxidants 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 2900 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Gibel carp (Carassius auratus gibelio) were hypoxia stressed for 12 h after an 8-week FPR nutrient-enriched feeding experiment, which was to evaluate the role of FPR in hypoxic stress in gibel carp (Carassius auratus gibelio). The dissolved oxygen was reduced to a range of 0.6 ± 0.2 mg/L. Results showed that FPR supplementation could maintain the osmotic pressure equilibrium by improving the ion concentrations of plasma including Na+, Ca+ and K+, and Na+/K+-ATPase activity of liver. FPR supplementation could effectively enhance the antioxidant capacity by improving the levels of GPX, SOD, CAT, and GSH, and reduce the level of MDA. FPR supplementation could improve the core gene expressions of Nrf2 signalling pathway including nrf2, sod, ho-1, gpx, and cat. The high levels of FPR supplementation (0.04%) might had a negative effect on immunity. FPR supplementation could improve the expression levels of HIF-1 signalling pathway-related genes to adapt to hypoxia condition including hif-1α, epo, angpt1, vegf, et1, and tfr-1. These results also were supported by higher SR and number of gill mitochondria in FPR supplementation. In general, the appropriate FPR supplementation was 0.01% based on the results of this study and economic cost, which could heighten hypoxic adaptation and SR. Full article
