AB The interest in fish welfare within aquaculture facilities has significantlyincreased over the past decade, recognizing the fundamental role of animal welfare in thequality of aquaculture products. It has been shown that stress in fish can affect their health,causing pathologies and immune failures, while stress-free fish grow faster and healthier.This has prompted aquaculture farmers to adopt strategies that reduce stress, improvewater quality, and optimize stocking densities, thereby enhancing fish welfare. A key areais the role of amino acids in improving fish welfare. Amino acids, such as histidine,isoleucine, leucine, and tryptophan, are essential for various physiological processes,including neurotransmitter formation, energy metabolism, and immune function. Aminoacids like tryptophan, arginine, and methionine play a crucial role in mitigating the effectsof stress, improving immune function, and reducing oxidative stress. In the presentreview, the main roles of those amino acids related to fish stress have been shown,analyzing the physiological pathways involved in the link between amino acid ingestionand metabolization and stress responses.
