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 food.For this purpose,a solution of hormone in pure ethanol used to spray on food.Feeding was done 3 times daily as an appetite.Comparing the mean values measured for length and weight using ANOVA.Results:Indicated with increase length and weight,the effects of the hormone get more distinct,so that with increase concentration of hormone,reduce weight and length.Conclusions:Estradiol along with testosterone and progesterone regulates final stages of oocyte maturation and ovulation.Various studies have proven the different concentrations of this hormone has different effects on the growth of different fishes.The aim of this study was to assess the effects of this hormone on growth factors of Carassius auratus. 展开更多
