Linolenic acid and/or ω3 polyunsaturated fatty acids (a mixture of 20:5 ω3 and 22:6 ω3) were incorporated at levels of 1% and 2%, respectively, into a corn oil control diet, and fed to red sea bream fingerlings. After a 45-day feeding period, it was found that the linolenic acid supplement did not improve the growth rate, whereas the ω3 polyunsaturated fatty acid sup-plement resulted in a marked improvement in the growth rate and feed efficiency. It is to be noted that highest growth rate and feed efficiency were seen in those fish fed a pollack residual oil which contained only trace amount of linolenic acid.
