生物方法:實務上可能無法移除。在其原生地,各種天敵(包括水母與魚)會吃 M. leidyi。黑海的 M. leidyi族群減少,在它的天敵之一,櫛水母 Beroe ovata,被引進該區之後。(Costello, 2001) M. leidyi在黑海的族群高度的發展,而在它的原生地北美洲河口水域裡面,卻沒有被觀察到族群膨脹的現象,原因之一是,北美洲沒有吃 M. leidyi的掠食者來控制它的族群大小。(Purcell et al., 2001)1997 年,另一個侵略者,櫛水母 Beroe ovataMayer 1912,,被發現於了黑海東北方。它是捕食者吃浮游生物的梳水母 - 尤其 M. leidyi.(Konsulov 與 Kamburskaya, 1998)正如其前任的 B. ovata經由壓艙水,從北美洲的相同沿岸水域抵達。(Seravin et al., 2002)B. ovata非常明顯地減少 M. leidyi族群,它已經讓黑海生態系統變形超過十年。M. leidyi族群的減少,限制它在生態系統上的影響力,結果是,我們觀察到黑海遠洋生態系統主要成份的恢復,例如 - 浮游動物(包括 meroplankton)、浮游植物、海豚與魚的以及他們的蛋與幼蟲.(Shiganova et al. 、 2000 a,b;2001 c) 意識到這一點,並銘記1990 年代M. leidyi對黑海與亞速海漁業破壞性的影響,2001 年我們開始了一些舉措,以估量形勢,審查和評估,並採取補救措施的具體行動。經過討論後,我們建議採用一種潛在的天敵M. leidyi作為唯一真正可行的選擇。正如黑海的例子所示,最好的而且到現在是唯一的候選物種是,另外一種櫛水母 Beroe ovata。在意外引進 Beroe ovata到黑海之後,M. leidyi的豐度立刻降低到低水準,而且沒有產生進一步的損害。事實上,生態系統幾乎立刻開始恢復。預期將 Beroe ovata引入里海,結果將會是相似的。預計在2003 夏天實施此計畫。(Dumont and Shiganova, unpublished)

A NATO ARW Workshop. 摘要: Proceedings of the Advanced Research Workshop (ARW) held on June 24-26, in Baku, Azerbaijan. The final conclusion of the workshop may be summarised as follows: all available wisdom strongly suggests to introduce Beroe to the Caspian as soon as possible, preferably in September 2002, and immediately thereafter initiate studies on Peprilus or fish with a similar feeding regime, as a medium-term possible final remedy. 5.
