The rapid expansion of the aquaculture industry comes with higher responsibilities towards the farmed animals, the consumer, and the environment. Societal aspects determine more and more the way the aquaculture related sectors are moving ahead. Our responsibility towards the animals we farm is that we offer a production environment that covers their needs for good health and welfare. New technologies must be environmentally friendly and the resulting aquaculture products affordable. New farmed fish species, new production technologies, new feed ingredients are emerging, all affecting the ways we must think to create solutions that work better, more efficiently and in a responsible way for both the farmed aquatic animal and the environment.

Under the complex conditions of intensive aquaculture, the relationships between nutrients, environment and metabolism of fish are changing. Increasing implementation of closed farming systems come with new challenges for both fish as well as the nutritional and technical properties of the feeds. New ingredients contain nutrients and potential anti-nutrients for farmed aquatic organisms, but little is known on their specific nature, concentrations, bioactivity, and potentially negative effects.
New farmed fish species are introduced, and the existing species are evolved through genetic selection programs. The nutritional requirements and metabolic capacities of those are largely unknown, still of utmost importance to ensure good health, welfare, and efficient growth.
A better understanding of nutrients, animal nutrient requirements and metabolism in fish is crucial to achieve responsible and sustainable precise aquaculture.

This Research Topic aims to collect studies (including original research, perspectives, reviews, and mini reviews) that investigate and discuss the following areas:

- nutritional impact of proteins, minerals, carbohydrates, and lipids on fish metabolism
- metabolic changes in fish induced by environmental changes
- climate change and altered fish access to proteins, minerals, lipids, and carbohydrates
- metabolic changes during growth and reproduction
- limitations of non-full fish meal raw materials as ingredients in aquatic feeds and respective mitigation strategies
- dietary replacement documentation studies in commercial farming setup
- genetic variation in metabolic responses to alternative dietary ingredients
- dietary lipid source or substitution in relation to lipid metabolism of fish
- dietary carbohydrate in relation to glucose metabolism of fish

We welcome the submission of different article types to this collection, especially reviews, mini-reviews, and original research papers. For a complete list of article types that can be considered in the Aquatic Physiology section, please follow this link

Even though abstract submission is not mandatory, we encourage all interested researchers to submit an abstract before submitting their manuscript. Abstracts do not have to coincide with the final abstract of the manuscripts.

Keywords: proteins, carbohydrates, fish, nutrients, metabolism, physiology, aquaculture, lipids, micronutrients


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
