In addition, year and sea age both significantly influence δ13C values (Year, n = 523, df = 17, F = 9.1, p\u003c0.001; sea age df = 1, F = 16, p\u003c0.001), with a significant interaction between all factors. These data strongly suggest that, in each sampled year, returning salmon from different natal origins fed in distinct locations. Stable isotope evidence for stock separation in feeding grounds is further explored in the supplementary information.","tracks":[]}
