Special Issue Information

Dear Colleagues, 

Within the next few decades, global food requirements will be between 60 and 120 million metric tons. Aquaculture is the fastest growing food production sector in the world and provides a steady supply of healthy and high-quality food, alongside providing economic security, particularly in rural areas. Therefore, the development of aquaculture is vital for food security and healthy economies. Improved aquaculture production is often accomplished through the intensification of production systems, which fundamentally relies on high stocking density, quality diets and limited water exchange. As aquaculture enterprises move towards more intensified production strategies, aquatic farms can often face devastation through infectious pathogens, water quality deterioration and reproduction depression, eventually resulting in production and economic inefficiencies. Aquaculturists are constantly searching for ways to enhance fish yields and resource use efficiency sustainably, with the associate benefits of increased business competitiveness and profits.

The aim of this Special Issue is to publish original research papers, case studies, and review articles focused on the latest advances in relevant aspects of fish production, fish health/disease, breeding, water quality issues, and overall economics. This includes novel strategies and the application of technologies to enhance the productivity of the fish farming industry and increase its economic and environmental benefits.

This Special Issue welcomes submissions from all experts working in the fields of aquatic environments, aquaculture, aquatic animal physiology, fish health, breeding, and stress mitigation, for both marine and freshwater environments.

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.

As the northern Largemouth bass (LMB) (Micropterus nigricans) industry shifts toward fingerling production, implementing practical feeding strategies to ensure efficient growth during high water temperatures is paramount. Twenty (12.7 ± 0.2 g) (Trial 1) and fifteen (7.2 ± 0.1 g) (Trial 2) LMB fingerlings were stocked in two recirculating systems (each containing nine tanks), acclimated to 30 °C, with one system fed daily rations of 3, 5 and 7% body weight (Trial 1), and the second system fed to satiation daily, every second day, or every third day (Trial 2), for 28 days each. All treatments were triplicated. Multiple growth metrics and lipid composition were analyzed. The 3% treatment yielded the lowest final average weight (36.05 g) and FCR (0.83), with no difference in final biomass in Trial 1 treatments. Fish fed to satiation daily and every second day produced FCRs and biomasses of 0.83 and 356.78 g, and 0.93 and 272.26 g, respectively. There were no differences in total lipid concentration, however, fatty acid profiles differed significantly between all treatments within their respective trials. Feeding LMB fingerlings 3% of total body weight or feeding daily to satiation allows for efficient growth at 30 °C and implements cost-effective feeding strategies. Full article
