<p>The River Tornionjoki drainage forms the northern boundary between Finland and Sweden. The main rivers and the smolt sampling location near the river mouth are highlighted.</p

Longitudinal variation of isotope ratios in fin ray and fin membrane.

<p>Comparison of the (a) carbon (<i>δ</i>¹³C), (b) nitrogen (<i>δ</i>¹⁵N), (c) hydrogen (<i>δ</i>²H) and (d) oxygen (<i>δ</i>¹⁸O) stable ratios of tip and base sections of the ray and membrane components of non-treated Atlantic salmon fins. 1:1 lines are added to each plot for visualisation purposes.</p

Variation of isotope ratios in salmon fin (TMB).

<p>Comparison of the (a) carbon (<i>δ</i>¹³C), (b) nitrogen (<i>δ</i>¹⁵N), (c) hydrogen (<i>δ</i>²H) and (d) oxygen (<i>δ</i>¹⁸O) stable isotope ratios of base and tip sections of non-treated Atlantic salmon fins. 1:1 lines are added to each plot for visualisation purposes.</p

Variation of isotope ratios between fin ray and fin membrane.

<p>Comparison of the (a) carbon (<i>δ</i>¹³C), (b) nitrogen (<i>δ</i>¹⁵N), (c) hydrogen (<i>δ</i>²H) and (d) oxygen (<i>δ</i>¹⁸O) stable ratios of ray and membrane components of tip, mid and base sections of non-treated Atlantic salmon fins. 1:1 lines are added to each plot for visualisation purposes.</p

Variation of isotope ratios in trout fin.

<p>Comparison of the (a) carbon (<i>δ</i>¹³C), (b) nitrogen (<i>δ</i>¹⁵N), (c) hydrogen (<i>δ</i>²H) stable isotope ratios of base and tip sections of non-treated anadromous brown trout fins. 1:1 lines are added to each plot for visualisation purposes.</p
