Following publication of the original article [1], the authors would like to apologize for an error in Fig. 5e, the correct graph is presented below and shows the significant increase in pituitary mRNA levels of fshb in recruited males in the SGA stage.

Fig. 5

Reproductive parameters in male Atlantic salmon (experiment 2) exposed to normal light (NL) or to continuous additional light (LL). Based on testicular proliferation activity (see Fig. 4) and independent of the photoperiod, individuals showing type A spermatogonia (SGA) as the furthest developed germ cell type were assigned to groups with a low or a high proliferation activity (Plow and Phigh, respectively). Within the further developed stages showing type B spermatogonia (SGB), or spermatocytes/spermatids (SC/ST), all males showed high proliferation activity, irrespective of the photoperiod. Plasma 11-ketotestosterone levels (11KT; a; ng/ml); GSI, gonadosomatic index (b); relative testicular mRNA levels of insulin-like growth factor 3 (igf3, c) or anti Müllerian hormone (amh, d); relative pituitary mRNA levels of fshb (e) or lhb (f). The number of individuals analyzed per group is given under the respective bars, showing means and SEM. In the SC/ST stage in e and f, statistical comparison has not been included due to the small sample size and the individual values are shown. Statistical differences within a given graph between males falling into the same treatment group but showing different spermatogenic stages are indicated by different lower case Latin or Greek letters (p < 0.05; one way ANOVA followed by SNK post hoc test). Statistical differences within a given graph between recruited fish showing elevated proliferation activity (Phigh) or non-recruited fish showing low proliferation activity (Plow) and between NL- or LL-exposed fish in the same stage of spermatogenic development are indicated by asterisks (Student t-test; *, p < 0.05; **, p < 0.01; ***, p < 0.001); the absence of an asterisk indicates the absence of statistically significant differences

The authors regret any inconvenience caused.
