Prostaglandin (PG) stimulates female spawning behavior in goldfish and in some other teleosts in which female reproductive behaviors consist of postovulatory oviposition acts. This study examined the effects of PG on female sexual behavior in a teleost fish, Cichlasoma bimaculatum, in which female reproductive behaviors involve both preovulatory courtship and substrate cleaning behaviors, and post-ovulatory oviposition behavior. In females of established pairs, PGF2 alpha injection (5 micrograms, im) at any stage of the spawning cycle, or in the parental phase, rapidly induced substrate cleaning which soon merged into oviposition behavior (without egg release). These results support a role for PG in oviposition behavior of Cichlasoma. However, indomethacin (1 mg, ip), a PG synthesis inhibitor, did not block oviposition in ovulated females which had begun to spawn. Indomethacin may not have lowered PG levels sufficiently. Alternatively, as shown by J.J. Polder (1971, Neth. J. Zool. 21, 265), oviposition behavior may be induced or maintained by other factors associated with the spawning situation.
前列腺素（PG）可刺激金鱼及其他一些硬骨鱼的雌鱼产卵行为，在这些硬骨鱼中，雌鱼的生殖行为包括排卵后的产卵行为。本研究考察了PG对丽鱼科双斑丽鱼雌鱼性行为的影响，在该鱼类中，雌鱼的生殖行为包括排卵前的求偶行为、清理底物行为以及排卵后的产卵行为。在已配对的雌鱼中，在产卵周期的任何阶段或亲鱼期注射前列腺素F2α（5微克，腹腔注射），均可迅速诱导清理底物行为，该行为很快会转变为产卵行为（但未排卵）。这些结果支持了PG在双斑丽鱼产卵行为中发挥作用。然而，PG合成抑制剂吲哚美辛（1毫克，腹腔注射）并不能阻止已排卵且已开始产卵的雌鱼产卵。吲哚美辛可能未能充分降低PG水平。或者，正如J.J. 波尔德（1971年，《荷兰动物学杂志》21卷，265页）所表明的，产卵行为可能由与产卵情况相关的其他因素诱导或维持。
