Europe is under a crab¹ invasion: They lay 1 million eggs at a time.

欧洲正遭受螃蟹入侵：它们一次产100万个卵。

This invasive species can survive on many different foods and can live on land as well as in fresh and salt water. Female hairy crabs² can also produce 250,000 to 1 million eggs at a time.

这种入侵物种可以依靠许多不同的食物生存，既可以生活在陆地上，也可以生活在淡水和咸水中。雌性大闸蟹一次也能产25万到100万个卵。

European scientists say hairy crabs are disrupting the food chain in rivers, spreading crayfish plague and increasing erosion of embankments and shores by burrowing³.

欧洲科学家表示，大闸蟹正在破坏河流的食物链，传播小龙虾瘟疫，并通过挖洞加剧对河堤和海岸的侵蚀。

Scientists are trying to stop the invasive crabs, which cause 12 billion euros a year in damage to the economies of EU members, in different ways.

科学家们正试图用不同的方法阻止入侵的螃蟹，它们每年给欧盟成员国的经济造成120亿欧元的损失。

The most effective solution so far has been a trap developed by Belgian researchers. The traps, developed by the University of Antwerp and the Flemish Environment Agency, are set with metal channels placed in rivers.

迄今为止，最有效的解决方案是比利时研究人员开发的陷阱。这种陷阱由安特卫普大学和佛兰德环境署共同研发，在河流中设置金属通道。

The crabs fall into these traps as they make their way along the river and start to move through a system of pipes connected to the mechanism⁴ in order to get out. However, the animals end up in cages placed at these points and are destroyed en masse.

螃蟹在沿河前行的过程中掉进了这些陷阱，并开始通过与机器相连的管道系统来逃脱。然而，这些动物最终被关在这些地点的笼子里，并被集体杀死。

Around 3 million invasive crabs have so far been caught in Belgium using this method, which has been in use since 2018.

自2018年以来，这种方法一直在使用，到目前为止，比利时已经捕获了大约300万只入侵螃蟹。
