Fish protein is a critical component in the human diet, offering high-quality protein rich in essential amino acids. Aquaculture provides a reliable supply of fish protein, reducing pressure on wild fisheries and helping meet global protein demands. In aquaculture, fish protein also serves as a feed ingredient, although sustainability concerns have led to increased use of plant-based alternatives. Fish protein is particularly valued for its health benefits, including cardiovascular support and essential nutrients. By focusing on sustainable fish farming, aquaculture helps supply nutritious protein sources to global markets while protecting natural fish populations.
