預防措施:養殖可能有入侵性的外來生物,並讓它們逃逸或釋放,會對本地生物多樣性和生態系統,產生負面的影響。Hewitt等人, (2006)養殖的外來物種:負責任的使用注意事項 ,提供決策者和管理者,現有的國際和地區性規定資料,解釋水產養殖業使用的外來物種,直接或間接的影響; 並舉三個國家(澳大利亞,紐西蘭和智利)對此問題的反應為例。該出版物還為發展中國家提供一個簡單的建議和一套指導方針和原則,可以應用在區域或國內一級負責管理外來物種的使用在水產養殖的發展。這些準則主要側重於海洋生態系統,但可能也同樣適用於淡水。 Copp等人,(2005)風險識別和評估非本地淡水魚類 提出了一個淡水魚風險評估方法的概念,包括英國環境風險策略的前兩個元素(危險源辨識,風險評估)。文獻中引入了一些物種評估的工作案例,以方便討論。電子決策支持工具,入侵物種識別工具,包括淡水魚和海水魚入侵性評分工具,可在Cefas(環境、漁業和水產養殖科學中心)網頁免費下載(官方版權所有2007-2008)。 大多數用來控制魚類族群的管理技術,並不能有效控制口孵魚。防止逃逸和小心放養,可以有效地防止其野生族群建立族群。應使用完全封閉的系統,來養殖藍口孵魚,並且只養在口孵魚已經入侵的水域。奧利亞口孵魚應該被禁止養在還沒有口孵魚既定族群的水域和湖泊中,(McCrary 等人, 2007)。 物理方法:1986年賓夕法尼亞州布倫納島,故意排放冷凝器的冷卻水,產生致命的低溫,疑除了奧利亞口孵魚。一項研究建議,溫度 5 °C持續16個小時,可有效消除奧利亞口孵魚(Stauffer等人, 1988; Costa-Pierce, 2001; Nico, 2007)。 生物方法:使用掠食性魚類Morone saxatilis X Morone chrysops和Sciaenops ocellatus可有效減少尼羅口孵魚與奧利亞口孵魚雜交種,在野外產卵。然而,把掠食性魚類引入野外,會有其他的生態影響。其他可能用來控制的掠食性魚類包括:蛇頭鱧(Channa striata),大眼海鰱(Megalops cyprinoides),尼羅河鱸魚(Lates niloticus),弗氏伴麗魚(Hemichromis fasciatus) 和淡水石斑(Cichlasoma managuens)(Milstein等人, 2000)。 尼加拉瓜湖的管理計劃,利用增加天敵數量,包括鱷雀鱔,Crocodrilus acutus,和Crocodrilus elasmobranchs,從幾十年之前已經大為減少奧利亞口孵魚,推薦使用這種方法(McCrary 等人, 2007)。 綜合管理:促進和增強奧利亞口孵魚的捕撈壓力以減少魚的平均尺寸,替其他魚類疼空出生態空間,是另一個指控制其族群的建議(McCrary 等人, 2007)。

Trinational Risk Assessment Guidelines for Aquatic Alien Invasive Species. Commission for Environmental Cooperation. 393, rue St-Jacques Ouest, Bureau 200, Montréal (Québec), Canada. ISBN 978-2-923358-48-1. 摘要: In 1993, Canada, Mexico and the United States signed the North American Agreement on Environmental Cooperation (NAAEC) as a side agreement to the North American Free Trade Agreement (NAFTA). The NAAEC established the Commission for Environmental Cooperation (CEC) to help the Parties ensure that improved economic efficiency occurred simultaneously with
trinational environmental cooperation. The NAAEC highlighted biodiversity as a key area for trinational cooperation. In 2001,
the CEC adopted a resolution (Council Resolution 01-03), which created the Biodiversity Conservation Working Group (BCWG),
a working group of high-level policy makers from Canada, Mexico and the United States. In 2003, the BCWG produced
the “Strategic Plan for North American Cooperation in the Conservation of Biodiversity.” This strategy identified responding to
threats, such as invasive species, as a priority action area. In 2004, the BCWG, recognizing the importance of prevention in addressing
invasive species, agreed to work together to develop the draft CEC Risk Assessment Guidelines for Aquatic Alien Invasive
Species (hereafter referred to as the Guidelines). These Guidelines will serve as a tool to North American resource managers
who are evaluating whether or not to introduce a non-native species into a new ecosystem. Through this collaborative
process, the BCWG has begun to implement its strategy as well as address an important trade and environment issue. With increased
trade comes an increase in the potential for economic growth as well as biological invasion, by working to minimize the potential adverse
impacts from trade, the CEC Parties are working to maximize the gains from trade while minimizing the environmental costs.
