The test diets contained 1.0% levels of 18:1ω9, 18:2ω6, 18:3ω3, 20:4ω6, or ω3-HUFA (60% 20:5ω3 and 40% 22:6ω3) in addition to 4.0% 18:1ω9 as dietary lipids. The highest weight gains were observed on the diets supplemented with 1.0% levels of 18:2ω6 or 20:4ω6. These indicated that T.nilotica requires ω6-fatty acids such as 18:2ω6 and 20:4ω6 rather than ω3-fatty acids in contrast to other fishes. However, the effects of water temperatures on the EFA requirements of T.nilotica were not clarified in the present study due to the poor growth of this fish at 20°C.}, pages = {201--204}, title = {Essential Fatty Acids of Tilapia nilotica}, volume = {31}, year = {} }
