Abstract: The objective of this work was to evaluate the effect of dietary arginine concentrations on the health status of Nile tilapia (Oreochromis niloticus) cultivated in cages. The experiment was carried out in a completely randomized design with four treatments (2.3, 2.9, 3.5, and 4.1% arginine in dry matter) and three replicates, in 12 net cages of 8 m3, containing 4,000 sexually reverted tilapia (63±20 g, at 500 fish m-3). Fish productive performance and health were evaluated. Biochemical, hematological, and immunological parameters, as well as the morphological aspects of gills and liver, were evaluated. Arginine inclusion did not cause significant differences in fish growth performance. However, arginine supplementation at 3.5% concentration improved the biochemical parameters and leucocyte counts, consequently improving the immune system. The arginine concentration of 4.1% caused lipid degeneration, shown by the increase of alanine aminotransferase and the decrease of albumin, urea, lactate, and glucose. Arginine supplementation above 2.3% and below 3.5%, in the diets of tilapia reared in cages, improves fish immune system, without adverse morphological and physiological effects.
