Optimizing aquafeed and nutrition is fundamental to ensuring the health, growth, and sustainability of farmed aquatic species. Formulating balanced diets with the right mix of proteins, lipids, vitamins, and minerals enhances feed efficiency while reducing waste and environmental impact. The shift from fishmeal-based diets to alternative protein sources, such as plant-based ingredients, insect meal, and microbial proteins, is transforming the industry, making aquaculture more sustainable. Advances in nutrigenomics are helping tailor diets to species-specific needs, improving immune responses and growth rates. Functional feeds enriched with probiotics, prebiotics, and bioactive compounds are also gaining attention for their role in enhancing disease resistance and gut health. With precision feeding technologies and automated monitoring systems, producers can optimize feed utilization, minimizing costs and ecological footprint. As demand for seafood rises, continuous research in Aquafeed and Nutrition is essential to developing sustainable solutions that balance productivity with environmental responsibility.
