采用短期连续投喂的方式，研究了不同浓度17β－雌二醇（0．25、0．50、0．75和1．00 mg／kg）对大鳞副泥鳅（Paramisgurnus dabryanus）生长和性腺分化的影响。结果显示：药物处理对大鳞副泥鳅成活率无显著影响；短期内（60 d）17β－雌二醇能显著促进大鳞副泥鳅的生长，其中低浓度（0．25 mg／kg）作用效果最明显；投喂60 d后，各浓度组的雌性比例（66．11％、71．67％、72．78％和71．11％）均明显高于对照组（56．67％），其中以0．75 mg／kg 组雌性比例最高。结果表明17β－雌二醇能促进大鳞副泥鳅未分化性腺向卵巢发育。

Growth and gonadal differentiation of Paramisgurnus dabryanus were observed with the diets adding different concentrations of 17β-Estradiol (0.25, 0.50, 0.75 and 1.00 mg/kg) in short period (60 days).The results showed that there were no significant difference in survival rate in different 17β-Estradiol levels.During the experiment time, the 17β-Estradiol could promote the growth of P.dabryanus, especially in the low concentration ( 0.25 mg/kg ) .Furthermore, the female P.dabryanus in the treatment group (66.11%, 71.67%, 72.78% and 71.11%) were signifi-cantly higher than the control group (56.67%), and the group of 0.75 mg/kg had the highest percentage of female.The results suggested that the 17β-Estradiol promoted the feminization of indifferent gonad in P.dabryanus.
