The growing demand for high-quality aquaculture products has prompted significant advancements in fish nutrition, with feed additives playing a crucial role. These additives, including probiotics, prebiotics, enzymes, amino acids, and plant-based compounds, improve growth performance, enhance immune responses, and elevate product quality in farmed fish. This review synthesises findings from various studies on the impact of feed additives on growth rate, feed conversion efficiency, health status, and fish meat quality. Probiotics and prebiotics enhance gut health, improving nutrient absorption and disease resistance, while enzymes optimize feed utilisation. Amino acids and vitamins address specific dietary needs, promoting faster growth and higher survival rates. Plant-based additives, such as essential oils and phytobiotics, exhibit antimicrobial and antioxidant properties, benefiting fish health and meat quality. Additionally, feed additives contribute to sustainability by improving feed efficiency and reducing waste outputs. The efficacy of these additives varies depending on factors like fish species, farming conditions, and dosage levels. This review underscores the potential of feed additives in promoting sustainable aquaculture and highlights the need for targeted research to refine formulations for diverse aquaculture systems.
