Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to the application of nutrition, physiological studies, and management carried out on fish.

Fish constitute the most diverse and ecologically important group of vertebrates in the world and, as such, have been extensively studied to understand the basic aspects of their development and to implement industrial applications. One of the most significant applications is aquaculture, which plays an important role in promoting the consumption of highly nutritious foods among the human population. In recent decades, fish have become valuable model organisms for biotechnology research, where nutritional and physiological studies are fundamental to achieving profitable aquaculture. Thus, the knowledge acquired from morphophysiological studies, through understanding the relationships between metabolic pathways and molecular mechanisms, has been revealed through the application of omics sciences. Therefore, the analysis of physiological processes not only expands our understanding of these animals but also has important implications for basic research and its application in improving management techniques for a more efficient aquaculture industry.

Considering the success of our previous Special Issue, we are pleased to launch "Fish Nutrition, Physiology and Management: Second Edition". This Special Issue will attempt to provide information regarding the relevance of nutrition, morphological and management techniques, and their relationships with functions in fish.

In this Special Issue, original manuscripts, review articles, and short communications, alongside research with the potential for application, are particularly welcome.

You are invited to contribute to this theme or related research topics to improve the existing anatomical and physiological knowledge of fish.

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. 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.

Early life nutrition is a critical factor influencing subsequent performance and quality, including skeletal development, in farmed Atlantic cod (Gadus morhua). This study investigated the effects of a novel start-feed protocol utilizing barnacle nauplii and plankton eggs and two experimental microdiets on larval survival, growth, skeletal anomalies, and organ ontogeny. Atlantic cod larvae were reared using three feeding protocols (COM, D1, and D2): COM used enriched rotifers and a commercial microdiet, while D1 and D2 protocols incorporated blue mussel eggs (Cryo-µ) and barnacle nauplii (Cryo-S, Cryo-L), followed by inert microdiets that differed in their phospholipid (PL) source (D1 richer in vegetable PL; D2 richer in marine PL). Larvae were sampled up to 66 days post hatching (dph) for morphometric, skeletal anomaly, and histological analyses. Survival averaged 21.3% and was unaffected by the diets. The control group had slightly higher standard length and dry weight at 66 dph compared to the experimental groups. However, larvae fed the D1 protocol exhibited a significantly lower overall prevalence of skeletal anomalies (52%) compared to the control group (91%). Moreover, D1 showed a lower occurrence of severe anomalies and a significantly reduced prevalence of scoliosis compared to both D2 and COM groups. Histology showed that group D1 achieved an overall accelerated organ ontogeny, with greater villi length and goblet cell abundance in the anterior intestine at 66 dph. In conclusion, the novel D1 feeding protocol, incorporating barnacle nauplii and a microdiet richer in vegetable phospholipids, enhanced larval quality by effectively reducing skeletal anomalies and accelerating internal organ development.
