  1. % WW, percentage of wet weight. Values are expressed as means ± SD (n = 57 individuals in all groups, except for muscle lipid content, for which n = 30); HIS, hepato-somatic index; VSI, Viscero-somatic index; p-values are presented in italics when the differences are significant (p < 0.05, MANOVA 2 factors). Means with different superscript letters are significantly different (p < 0.05, ANOVA).
