Özet:

Proximate and amino acid composition of the whole body tissue of juvenile Oreochromis aureus, Tilapia rendalli, Tilapia zillii, Tilapia spp. and Oreochromis niloticus were determined. Accordingly, protein and lipid levels in whole body were found higher in Tilapia rendalli than the other species. The amino acid composition was significantly different among species when expressed as g/100g amino acids. Although aspartic acid levels were different in all species, other amino acid levels were not highly different among the species. Similar findings were available for the A/E ratios ((each essential amino acid content/total essanstiel amino acid content) × 1000). However leucine, lysine and aspartic acid were higher, methionine, histidine and tyrosine were lower for all species.
