摘      要：Objective:To evaluate the effects of 17-beta-estradiol on growth factors of goldfish(Carassius auratus).Methods:To perform the test,17-beta-estradiol was given 3 months period to fish at different doses as followed:control group,Group 1:10 mg/kg food,Group 2:25 mg/kg food and Group 3:50 mg/kg *** this purpose,a solution of hormone in pure ethanol used to spray on *** was done 3 times daily as an *** the mean values measured for length and weight using ***:Indicated with increase length and weight,the effects of the hormone get more distinct,so that with increase concentration of hormone,reduce weight and ***:Estradiol along with testosterone and progesterone regulates final stages of oocyte maturation and *** studies have proven the different concentrations of this hormone has different effects on the growth of different *** aim of this study was to assess the effects of this hormone on growth factors of Carassius auratus.
