Fig. 6. Abundance of messenger RNA of (A) glucocorticoid receptor 1 (rtGR1), (B) glucocorticoid receptor 2 (rtGR2) and (C) 11ß-hydroxysteroid dehydrogenase (11ß-HSD) in the whole ovary of rainbow trout females sampled at three stages of ovarian development: late vitellogenesis (LV, 3–4 weeks before expected ovulation, N=6), prior to germinal vesicle breakdown (preGVBD, N=8) and during oocyte maturation (MAT, N=6). Values are mean ± s.e.m. Different letters indicate significant differences between stages (P<0.05).
