摘要
研究了 4种不同激素 (17α -羟孕酮、 5-羟色胺、前列腺素和保幼激素 -Ⅲ )的体外注射对中国对虾 (Penaeuschinensis)卵巢发育的作用效果 .试验结果显示 :用 10 0ng/g浓度的 17α 羟孕酮和 5 羟色胺注射亲虾对对虾卵巢的发育有明显的刺激作用 ,生殖指数分别比对照组增加了 50 0 %和 4 4 7% .而同样浓度的前列腺素和JH Ⅲ的体外注射作用不明显 .在相同条件下 ,去眼柄对对虾卵巢的发育作用最明显 ,生殖指数比对照组增加了 150 % .文中还讨论分析了几种激素的属性和对虾卵巢发育的作用机理 .
Four kinds of hormones (17α hydroxyprogesterone, 5 hydroxytryptamine, prostaglandin E and juvenile hormone Ⅲ) were injected into the parent shrimp Penaeus chinensis with a dose of 10 ng/g for stimulation of ovarian development The results showed that 17α hydroxyprogesterone and 5 hydroxytryptamine had significant stimulation of the shrimp ovary,and the gonad somatic index (GSI) increased by 50 0% and 44 7% respectively over the control group. However,prostaglandin E and juvenile hormone Ⅲ showed insignificant effects on the shrimp ovarian development.In the eyestalk remove group,the ovary of the parent shrimp develoed most rapidly,and the GSI increased by 150% and 50% over the control group and the hormone injected groups.
