Sample sizes for morphological measures and gill ATPase activity by rearing treatment and smolt phenotype—female.

Sample sizes of juvenile female steelhead sampled at Winthrop National Fish Hatchery separated according to rearing treatment (S1, S2), release year (2011–2015), and visually determined qualitative smolt phenotype (parr, transitional, smolt). Morphological measures and gill ATPase activity are represented in Fig 3 and S9–S11 Figs with sample sizes corresponding to individual bars. Abbreviations and units of measure are as follows: fork length (mm); body weight (g); gill Na+/K+ ATPase activity (μmol ADP · mg protein-1 · hr-1).
