Methallibure treatment (1 mg fed on alternate days to a female and a male kept in 1 liter of 25% seawater) started from 1 or 7 days postpartum (early gestation) inhibited gestation in the wild guppy, Poecilia reticulata. A few of the fish treated from 7 days postpartum (2/9) did give birth, but the young either were dead at birth or did not survive long after birth. When treatment was started 2 weeks postpartum (midgestation), gestation was not inhibited, but 25% of the young were born dead while the rest showed retardation of postnatal growth. Several possible interpretations of the results are discussed.
从产后1天或7天（妊娠早期）开始，对饲养在1升25%海水中的一雌一雄野生孔雀鱼（孔雀鱼）进行美他利脲处理（每隔一天喂食1毫克），会抑制其妊娠。产后7天开始处理的一些鱼（2/9）确实产仔了，但幼鱼要么出生时就死亡，要么出生后存活时间不长。当在产后2周（妊娠中期）开始处理时，妊娠没有受到抑制，但25%的幼鱼出生时死亡，其余幼鱼则表现出出生后生长发育迟缓。文中讨论了这些结果的几种可能解释。
