Factorial ANOVA followed by Tukey post hoc. Means within a column followed by different letters (a, b, c, d, e, f, g, and h) are significantly different () with respect to the type of FAs, which result in %. ^aMean = mean ± std. dev, L. minor^RC = Reported percentage composition in L. minor, Nile tilapia^RC = reported percentage composition in Nile tilapia fed with 20% L. minor. nr: not reported.
