产卵

Female echidna lay eggs in temporary ago, about 7-10 days, began to develop a child care bag.

Carp spawned earlier in water of rising temperature,but the eclosion rate was very low in early spring.

水温升高使鲤鱼的产卵期提前，但是在早春的孵化率很低。

Vg could be detected in haemolmph of the water—fed female at 48h after eclosion, too.

用10％的蜂蜜和清水分别饲喂两组成虫(简称"蜜组"和"水组")，以研究成虫期的营养对Vg发生和卵巢发育的影响，结果显示，成虫期营养对于Vg的启动合成并不起关键的决定性作用，两组成虫均可以在羽化的48小时检测到Vg，且水组中的血淋巴水平并不低于蜜组对照，但绝大多数水组个体的卵巢发育停留在卵黄沉积的某一时期，此时在血淋巴中也检测不到，只有约20％的饲水个体卵巢可以发育成熟，出少量卵；用高剂量的ZR515于羽化当日点滴处理饲水个体，可以使所有接受处理的饲水个体的卵巢发育成熟，但是产卵〓依旧低于对照组的，不能恢复正常；这说明成虫期营养对卵巢中全体卵母细胞的成熟是必需的，其作用的产生是通过内分泌系统途径实现的。

This paper also analyzed the relationship between the sex ratio and the laying order in the broods of Little Egret and Chinese Egret.

本文还探讨白鹭和黄嘴白鹭的产卵顺序与雏鸟性别之间的关系。

The results showed that the reproductive system of female adult was constituted by a pair of ovaries, a pair of lateral oviducts, median oviduct, bursa copulatrix, spermatheca, genital chamber and ovipositor. The reproductive system of male adult was constituted by a pair of testes, a pair of vas deferens, a pair of male accessory glands, ejaculatory duct and penis.

结果表明：雌成虫的生殖系统由1对卵巢、1对输侧输卵管、中输卵管、交配囊、受精囊、生殖腔和产卵器组成；雄成虫生殖系统由睾丸、1对输精管、1对附腺、射精管和阳茎组成。

If they're shedding an exoskeleton or laying eggs,that's even better.

Don't know, have a person to know, the sea turtle produce the time that the egg expect to choose to leave a farer place of the seaside, this is why?

不知道，有没有人知道，海龟产卵期的时候都选择离海边比较远的地方，这是为什么呢？

During the 3 breeding cycle, we have research successfully on the laying eggs, fecundation, artificial incubation, artificial fostering nestlings , and the nestling growth in captivity.

终于在大鸨人工饲养条件下产卵、受精、人工孵化、人工育雏及雏鸟的生长发育等方面的研究上取得了成功，同时还对大鸨的骨骼解剖，羽毛微观结构观察及成分分析，生殖系统解剖、消化系统解剖及消化系统组织学疾病防治进行深入的研究。
