Abstract

Since destalked immature female Libinia emarginata fail to molt to maturity (Hinsch, 1972) and implants of thoracic ganglion of adult females into young females of Potamon dehaani caused a doubling of ovarian weight and differentiation of yolk granules (Otsu, 1963), the effects of the thoracic ganglion implantation on sexual maturation in Libinia was investigated. Destalked immature Libinia with a maximum carapace length of 4-5 cm received two implants of adult female thoracic ganglion at 10-day intervals. All of the surviving experimental animals and destalked controls molted to immaturity. Most of the experimental animals failed to complete a successful molt and few survived longer than 3-4 days. The experimental animals that survived for over a week showed signs of yolk deposition not observed in the destalked controls. Eggs in several stages of vitellogenesis were scattered throughout the gonad in the animal showing the most pronounced effect. This was not observed in any of the destalked controls.

摘要

由于摘除眼柄的未成熟雌性锯齿哲蟹无法蜕皮至成熟阶段（欣施，1972年），并且将成年雌性中华绒螯蟹的胸神经节植入德氏束腹蟹的幼体雌性体内会导致卵巢重量加倍以及卵黄颗粒分化（大津，1963年），因此对胸神经节植入对锯齿哲蟹性成熟的影响进行了研究。摘除眼柄且最大甲壳长度为4 - 5厘米的未成熟锯齿哲蟹每隔10天接受两次成年雌性胸神经节植入。所有存活的实验动物和摘除眼柄的对照动物均蜕皮至未成熟状态。大多数实验动物未能成功完成蜕皮，很少有存活超过3 - 4天的。存活超过一周的实验动物表现出在摘除眼柄的对照动物中未观察到的卵黄沉积迹象。在显示出最明显效果的动物中，处于不同卵黄发生阶段的卵散布在整个性腺中。在任何摘除眼柄的对照动物中均未观察到这种情况。
