We compared the abilities of pupfish, mosquitofish and guppies to control mosquitoes in wastewater marshes. All species of fish reduced mosquito emergence. When fish population densities were similar, fish reduced emergence to similar levels. As experiments progressed, guppies developed greater population densities and provided better mosquito control than mosquitofish, which developed greater densities and better control than pupfish. Fish also reduced numbers of zooplankton, and guppies increased total plant biomass, suggesting fish may influence the ability of wastewater marshes to treat wastewater.
我们比较了鳉鱼、食蚊鱼和孔雀鱼在废水沼泽中控制蚊子的能力。所有鱼类都减少了蚊子的羽化。当鱼类种群密度相似时，它们将蚊子羽化减少到相似水平。随着实验的进行，孔雀鱼的种群密度变得更大，并且比食蚊鱼能更好地控制蚊子，而食蚊鱼的种群密度又比鳉鱼更大，控制效果也更好。鱼类还减少了浮游动物的数量，孔雀鱼增加了植物总生物量，这表明鱼类可能会影响废水沼泽处理废水的能力。
