摘要

臺灣省淡水紅樹林網紋招潮蟹（Uca arcuata）的卵巢呈H型，幼小或非生殖期的卵巢是白色，成熱的卵巢為橘黃或淡紫色。雌性網紋招潮蟹的生殖期均在每年的一月到三月和六月到八月，並可能在四月裏脫皮。卵發生的過程根據卵細胞的形態可分為五期：即卵原細胞、第一期、第二期和第三期卵細胞以及退化的卵細胞。在第二期卵細胞胞質中首先可見卵黃粒，第三期卵細胞中有多量的卵黃，此期即為成熱的卵細胞。如成熟卵未被排出，卵巢即將卵內的物質吸收，而形成退化的卵細胞。

並列摘要

Ovaries of Uca arcuata collected at Tan-Shui mangrove swamp on Taiwan were studied for oogenesis. The ovary of immature or non-breeding female crab is white in color and becomes orange or purple when the ovary is mature and in breeding season. The breeding season of Uca arcuata is between January and March and between June and August. Female crab may enter molting in April. According to the histological studies, the oogenesis is scheduled as: oogonium, stage 1, 2, 3 oocyte and reabsorbed oocyte. Yolk granules are first found in stage 2 oocyte. Oocytes have full of yolk granules and reach mature at stage 3. If mature oocytes were not released during breeding season their cellular contents were then reabsorbed by the ovary.
