Proportions (left) and concentrations (right) of saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids with the sums of n-3 and n-6 series of PUFAs of 2-sea-year-old salmon at the start of the spawning run in the sea and at spawning time (see legend in Fig. 1). Significant differences (p < 0.05, post hoc SNK in one-way ANOVA) in the means between the sampling locations are indicated with no common letter. The number of specimens is given in parentheses. In both columns, note the different scale in the y-axis of n-6 PUFA
