2.4. Statistical analysis
Data from individual fish were treated as independent samples.
Muscle total lipid and fatty acid composition were subjected to
one-way analysis of variance (ANOVA) and differences were
considered significant at an alpha value of 0.01. Analyses were
performed using SPSS statistical package (version 13.0, SPSS Inc.,
Chicago, USA). Data that were identified as non-homogeneous
(using Levene’s test of homogeneity) were subjected to either log
or power transformation before analysis. Differences between
means were determined by Tukey’s test.
