Developmental expression and estrogen responses of endocrine genes in juvenile yellow perch (Perca flavescens)

► Key endocrine genes were measured in male and female juvenile yellow perch. ► Pituitary gh and liver igf1b mRNA were correlated with growth in both sexes. ► Sex-specific expression of liver estrogen receptors was found. ► Dietary estrogen increased liver esr1 mRNA expression.
