Expression of igfbp1b (A), igfbp2b (B), igfbp4 (C), igfbp5a (D) and igfbp6b (E) mRNA in kidney, skeletal muscle, anterior intestine, gill, brain, pituitary and liver of fed, freshwater-acclimated, tilapia. Data were normalized using ef1αas a reference gene and are presented relative to the amount of mRNA in kidney. n.d.; no detection. Groups not sharing the same letter are significantly different (ANOVA, Tukey’s HSD, P < 0.05). Means ± SEM (n = 6–8).
