Determination of Fatty Acid Compositions of Five Different Tilapia Species from the Çukurova (Adana/Turkey) Region


Abstract: The fatty acid compositions of Tilapia rendalli, T. zilli and Oreochromis aurea reared in cages located in Seyhan Dam Lake, O. niloticus reared in freshwater ponds and Tilapia spp. from the Seyhan River were compared. The fatty acid levels of Tilapia spp. from the Seyhan River were significantly higher than those of the other groups (p < 0.05). Total \omega-3 fatty acid values were significantly different for all groups and the highest level were found in Tilapia spp. (p < 0.05). The ratio of \omega-3/ \omega-6 for Tilapia spp., O. aurea, T. rendalli, T. zilli and O. niloticus were 1.95, 1.37, 1.29, 1.21 and 1.12, respectively.
