Abstract

This study was aimed to determine proximate composition (protein, lipid and ash) and moisture percentage, as well as amino acid profiles of the four species Asian sea bass (Lates calcarifer) cultured in cage condition, Rainbow trout (Oncorynchus mykiss), Common carp (Cyprinus carpio) and Neil Tilapia (Oreochromis niloticus). The results showed that amount of moisture and crude protein in Asian sea bass was significantly higher than three other species (p<0.05). But, the amount of crude fat and ash in common carp was significantly higher than other species (p <0.05). The amount of essensial and nonessensial amini acids showed a significant difference (p<0.05). Based on the results, ΣEAA and ΣNEAA in the O. mykiss was significantly higher than the three other species (p <0.05). The proportion of ΣEAA to ΣNEAA showed a significant difference among four species (p<0.05). The highest of proportion of ΣEAA to ΣNEAA was observed in Nile Tilapia and the lowest of ΣEAA/ ΣNEAA was recorded in Common carp. In conclusion, it seems that Asian sea bass and Rainbow trout have a higher nutritional value for consumers than common carp and Nile Tilapia.
