中文摘要:
      研究了性腺未分化年幼鲻鱼,通过口服不同剂量的17β-雌二醇控制其雌性化.研究结果表明,高剂量组被诱导为全雌鲻鱼,低剂量组雌性率达90%,而对照组则为雄鱼.雌性性分化早于雄性.17β-雌二醇在肌肉和胃肠道残留量低,残留时间短.
英文摘要:
      The paper was to investigate the control of sexual differentiation by oral administration of varying doses of 17β2estradiol ( E2) in juvenile grey mullet , Mugil cephalus with sexual undifferentiation. The results indicated that the grey mullets in the high dosage group were induced to be all2female , and 90 % of the juvenile grey mullets in the low dosage group differentiated into female. The control group differentiated into all2males . Sexual differentiation into females occured significantly earlier than in males. The residue level and residue time of 17β2 estradiol were low and short in the muscle and gut of grey mullets.
