Fig. 2
a Size of scales (mean mm2 ± SE in different salinities) collected using two different sampling methods (M1 and M2; see text). b Growth rate (mean radioactivity counts/mm2 ± SE) of herring juveniles in different salinities. G(I) = growth rate of scales according to scale sampling method M1; G(II) = growth rate according to scale sampling method M2; C(I) and C(II) = counts of radioactivity in control scales in the two methods M1 and M2, respectively. See Table 1 for the values of P in pairwise comparisons of G(I)
