Fish in Troubled Waters直译是：“浑水里捕鱼”，出自《伊索寓言·渔夫》
这篇寓言江的是：有个渔夫在河里张网捕鱼，他把鱼网横栏在河道里，然后拿了一条缚着石块的绳子，不停的拍击河水，使泥沙泛起，河水浑浊，鱼儿在慌乱中纷纷自投罗网，渔夫用这个方法捕得了好多鱼。但住在附近的人指责渔夫说：“我们饮水全靠这条河，你把水搞得这么浑，叫我们到哪里去找清水饮用呢?” 渔夫回答说： “可是，我若不把水搞浑，那就非饿死不可了”
因此，人们常用to fish in trouble waters 比喻to try to win advantages for oneself from a disturbed state of affairs; to make use of sb's misfortune to serve one's own ends.并因此产生了谚语it’s good fishing in troubled waters(混水好摸鱼)。
在英语中，to fish in troubled waters 也可写成to fish in the muddy waters，而且water必须做waters。
eg:The man who interferes in South American politics is fishing in troubled waters
I refused to let them come here because i knew they only wanted to fish in troubled waters
Those who made large profits out of illegally selling rationed goods during World War II were fishing in troubled waters.
