One-way ANOVA was used to compare the growth and feeding
data, whole body proximate composition and liver and fillet fatty
acid composition. Homogeneity of variances was tested using
Levene’s test and multiple comparisons among treatments were
performed using a Tukey HSD post hoc test. Treatment effects were
considered significant at P < 0.05. The statistical package SPSS
(v.12.0 for Windows) was used for all statistical analyses
