澳洲政府已編列1,500萬澳幣聯邦預算，滅絕其淡水水域中的最大禍害：鯉魚。
澳洲鯉魚數量已多到失控，此一外來入侵物種，已佔澳洲墨累大令盆地（Murray-Darling basin）魚類總量的80%。
成年鯉魚在澳洲沒有天敵，且能適應各種環境，因此很容易奪走原生魚類的食物和資源。
目前魚群數量的控制方法，如誘捕或商業捕魚，對於大範圍的鯉魚數量影響甚微，因此政府必須想出更有創意的辦法，來控制不斷增加的鯉魚。
澳洲計畫在墨累大令盆地，散播一種鯉魚特有的皰疹病毒，該病毒會附著在鯉魚表皮、鰓、和腎臟上，令鯉魚難以呼吸。
這種病毒會在鯉魚體內增殖一星期，當魚出現感染病灶後，約24小時內，就會死亡。
此種病毒會殺死大部分的鯉魚，而對澳洲原生魚類，或其他水生動物，並無影響。
政府編列的1,500萬澳幣預算，大部分是用來清理鯉魚屍體。
英文原文：
The Australian government has committed AUD$15 million of its federal budget toward eradicating its biggest freshwater pest: the common carp.
Australia’s carp population has gotten so out of control that the invasive species makes up 80 percent of the fish biomass in Australia’s Murray-Darling basin.
Adult carp, as they have no natural predators in Australia and can adapt to different environments, easily outcompete native fish species for food and resources.
As current population control measures such as trapping and commercial fishing have had little effect on carp populations over large areas, the government has had to get a little more creative to combat the rising carp population.
Australia plans to release a carp-specific herpes virus into the basin. The virus attaches to their skin, gills and kidneys and makes it difficult for the fish to breathe.
The virus multiplies in the carp for about a week, and fish usually die 24 hours after they first show signs of the virus.
While the virus kills the majority of carp populations, it has no effect on native fish species or other aquatic animals.
Much of the $15 million the government has set aside for the project will go towards cleaning up the dead carp.
