Abstract—Eighteen amino acids were detected in both sexes of Rhabdosargus sarba , 10 Essential Amino Acids (EAA) and 8 Non Essential Amino Acids (NEAA), females had higher concentration of EAA (2365 μg/mg) than males (1513 μg/mg); however males had higher concentration of NEAA (2418 μg/mg) than females (1614 μg/mg). In females, the minimum concentration of total EAA (2192.6 μg/mg) was in nearly ripe stage but the maximum concentration (2595 μg/mg) was in ripe ovaries. The maximum concentration of total NEAA was during spawning (2584.6 μg/mg) but the minimum concentration (1043.5 μg/mg) was in ripe stage. The EAA Arginine, Histidine, and Tryptophan were significantly higher ( P <0.05) in males than females, whereas Lysine, Valine, Leucine, and Methionine were significantly higher ( P <0.05) in females than males. The NEAA Aspartate, Proline, and Glutamate were highly significant ( P <0.05) in males than females, hwoever Glycine and Threonine were significantly higher in females than males.
