FIGURE 3 Mean [S.E.; n = 30; (a), (c), (d)] Salmo salar growth in mass (M) fork length (LF) and Fulton's condition factor (K) measured in freshwater (15 April 2016) and during the post-smolt phase (1–2 June; 1–2 June and 29–30 August 2016) (a) Measured mass () Preline, and () Reference, (b) estimated mean mass (Fishtalk calculations, CEF = 1.1) () Reference, and () Preline, (c) mean fork length () Preline, and () Reference and (d) condition factor (K) () Preline, and () Reference. Estimated mean mass covers both the post-smolt phase 5 May to 30 August, and the growth phase 31 August to 30 November. Changeover is indicated with a dot in the figure. SW, seawater. Significant difference between groups; *p <0.05; ***p <0.001
