在过去的几年中，巴拿马的养鱼者一直使用 Onuphid 多毛类管虫 Americonuphis reesei Fauchald（Fauchaid 1973）作为膳食补充剂，以加速南美白对虾 Boone 和 P. stylirostris Stimpson 的性腺成熟。这种补充剂的成功导致了该蠕虫的小规模捕捞，并将其出口到厄瓜多尔、伯利兹和危地马拉的虾农。蠕虫被冷冻并切碎喂给成年虾。 Mariculturist 使用颗粒蠕虫的努力未能产生预期效果。这表明生物活性化合物是不稳定的。对蠕虫组织中大量脂质含量的目视观察表明，活性化合物本质上可能是脂质的。前列腺素 (PG) 是源自花生四烯酸 (AA) 的脂质化合物，是具有高激素样活性的活性分子 (Totora 和 Anagnostakos 1981)。已知这些分子在许多物种的生殖周期中发挥重要作用。例如，PGs 诱导海洋双壳类和腹足动物的性腺成熟和配子释放（Morse 等，1977）。
During the past few years, mariculturists in Panama have been using the Onuphid polychaete tube-worm Americonuphis reesei Fauchald (Fauchaid 1973) as a dietary supplement in order to accelerate gonad maturation in the penaeid shrimps Penaeus vannamei Boone and P. stylirostris Stimpson. The success of this supplement has led to a small fishery of the worm and its export to shrimp farmers in Ecuador, Belize and Guatemala. The worm is frozen and fed chopped to the adult shrimps. Mariculturist's efforts to use pelletized worms failed to produce the expected results. This suggested us that the bioactive compounds are labile. Visual observation of a large lipid content in the worm tissues suggested that the active compounds might be lipidic in nature. The prostaglandins (PGs), lipid compounds derived from arachidonic acid (AA), are active molecules with high hormone like activity (Tortora and Anagnostakos 1981). These molecules are known to play an important role in the reproductive cycle of numerous species. For example, PGs induce gonad maturation and gamete release in marine bivalves and gastropods (Morse et al 1977).
