Molecular confirmation of the effect of the hypoxic stimulus on targeted oxygen-sensitive genes in non-hatched embryos and early hatched alevins. The relative abundance of mRNA of (a) hypoxia-responsive genes, (b) glucose transport genes and (c) pyruvate conversion and lactate transport genes in embryos (kept under normoxia, white bars; exposed to hypoxia, slash bars) and in alevins (kept under normoxia, grey bars; exposed to hypoxia, black bars). Data are presented as the mean ± SD (n = 6), significant differences were evaluated by nonparametric Kruskal-Wallis test followed by a Tukey’s test (# p < 0.05; *p < 0.001).
