Special Issue Information

Dear colleagues,

Aquaculture is presented as one of the main alimentary industries for the provision of the increasing protein demand for the maintenance of the growing planetary population. However, the sustainability and productivity of the aquaculture industry has to deal with different challenges, some of them related to the effects of the workaday procedures on the physiology of farmed fish. One of the main consequences of these farming activities is the stress suffered by the farmed fish that lead to several problems, as is the reduction of appetite or immune depression, as has been reported in many fish species with commercial interest. Thus, the aim of this Special Issue is to publish original research papers or reviews concerning the characteristics and consequences of the physiological stress response in commercial fish species. 

Areas of interest: physiological stress response in novel farmed fish species; the effect of stress on animal behavior (feeding, reproduction) and health (welfare, illness); methods for improving stress consequences (dietary composition, additives, and anesthetics); slaughter methods and stress in farmed fish (welfare, meat quality). 

I invite you to share your recent findings through this Special Issue.

Dr. Marta Conde-Sieira

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.

Plant extracts are known for their high content and diversity of polyphenols, which can improve fish oxidative status. A growth trial with Senegalese sole postlarvae (45 days after hatching) fed with one of four experimental diets—control (CTRL), and supplemented with curcumin (CC), green tea (GT), and grape seed (GS) extracts—was performed to assess if supplementation could improve growth performance and oxidative status. At the end of the growth trial, postlarvae were submitted to a thermal stress to assess their robustness. Sole growth was improved by CC and GS diets when compared to those fed the CTRL. CC and CTRL postlarvae presented the lowest oxidative damage (lipid peroxidation and protein carbonylation values). Stress-related biomarkers (heat shock protein 70 and glutathione-S-transferase) decreased in CC fish compared to those fed the CTRL diet, which might be due to a direct antioxidant capacity. In contrast, oxidative damage increased in GT and GS sole reared in standard conditions. However, after a thermal stress, GT and GS diets prevented the increase of protein carbonylation content and the decrease of antioxidant glutathione, depending on exposure time. Overall, dietary supplementation with natural extracts modulated oxidative status and stress response after a short/long-term exposure to temperature. Full article
