Fig. 1. Relative mRNA abundance of Egf(A), Igf I (B) and Igf II (C) in the liver of grass carp fed with chironomid larvae (open bars) or fed with duckweed (filled bars). The hatched
bars show the relative mRNA abundance of genes in control group (0 day). Data are presented as mean ± standard error (n = 6). A value followed by a superscript differs signif
icantly (P b 0.05) from all other values not followed by the same superscript in the same kind of columns
