将雌性克氏原螯虾暴露于10 ppm萘中，以确定其对卵巢发育的影响。在暴露于萘1、2、4、6、8、10、12和15天后，取出卵巢进行检查。将暴露于萘15天的小龙虾放回清洁的淡水中1、2、4、5、7、10和15天，以确定卵巢是否会从萘暴露中恢复。反映卵巢重量的卵巢指数在15天的萘暴露期内逐渐下降。卵黄发生期和卵黄发生期卵母细胞退化。强烈闭锁沿着卵黄吸收导致卵巢指数下降。相反，对照组的卵巢发育成成熟的性腺。但经净化处理的克氏原螯虾卵巢中仍有未成熟的卵母细胞出现，表明克氏原螯虾卵巢可以从萘引起的闭锁中恢复。
Female crayfish, Procambarus clarkii, were exposed to 10 ppm naphthalene to determine its effect on ovarian development. Ovaries were removed for examination after 1, 2, 4, 6, 8, 10, 12, and 15 days of exposure to the naphthalene. Crayfish that had been exposed to naphthalene for 15 days were then returned to clean freshwater for 1, 2, 4, 5, 7, 10, and 15 days to determine whether the ovaries would recover from the naphthalene exposure. The ovarian index, which reflects the weight of the ovary, decreased gradually over the 15-day naphthalene exposure period. The previtellogenic and vitellogenic oocytes degenerated. Intense atresia along with yolk resorption led to this decrease in the ovarian index. In contrast, the ovaries of the control crayfish developed into ripe gonads. However, immature oocytes reappeared in the ovaries of the crayfish subjected to depuration, which suggests that the ovary of P. clarkii can recover from naphthalene-induced atresia.
