The 2-sea-year-old Baltic salmon were sampled during the spawning run from the southern Baltic Sea to the rivers running into the Bothnian Bay. 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 as a superscript to the SE value of the appropriate mean. The number of specimens (N) is also given
