The catfish effect is the effect that a strong competitor has in causing the weak to better themselves.[1] Actions done to activelyapply this effect (for example, by the human resource department) in an organization, are termed catfish management.[2]
In Norway, live sardines are several times more expensive than frozen ones, and are valued for better texture and flavor. It was said that only one ship could bring live sardines home, and the shipmaster kept his method a secret. After he died, people found that there was one catfish in the tank. The catfish keeps swimming, and the sardines try to avoid this predator. This increased level of activity keeps the sardines active instead of becoming sedentary, according to Vince from the Catfish film.[citation needed]
In human resource management, this is a method used to motivate a team so that each member feels strong competition, thus keeping up the competitiveness of the whole team.
The exact origin is unknown. There are very few discussions of this effect in the English literature, but it is widely cited and discussed in the Chinese literature such as library research.[3]

https://zh.wikipedia.org/wiki/鲶鱼效应
鯰魚效應（Catfish Effect）是指透過引入強者，激發弱者變強的一種效應。[1]
在挪威，鮮活的沙丁魚比急凍的要貴好幾倍。有說，在當地長期以來只有一艘漁船能做到將鮮活的沙丁魚帶上岸。而箇中祕訣只有船長一人知道，而且始終沒透露半句。船長離世之後，漁民在他的漁獲盛器中發現一條鯰魚東游西竄，沙丁魚為閃避它而改變其一貫的惰性，不停游動，以求保命，終得以存活下來。[來源請求]
但目前未见来自挪威及其他国家的文献佐证该说法，此說除了常見於中国文史資料。
鲶鱼效应是真是假？https://www.zhihu.com/question/30085897
………养小鱼有个简单的定律就是“一英寸一加仑”，意思是每3.8升水里边只能养活一条一英寸长的鱼，或者想养一条两寸长的鱼就得准备7.6升水。
…………那个鲶鱼，咱先不说淡水鱼丢海水里腌咸鱼的问题了。。。你们语文老师确定沙丁鱼傻到分不清自己同类长啥样？
…………同样空间，剧烈运动耗氧量应该加剧，含氧量不变的情况下，啧啧。也许沙丁鱼有特异功能呢？
…………北大西洋没有啊，带条淡水鲇鱼出海扔进海水养殖池也是蛮拼的，有机会我想采访一下鲇鱼的感受。

我改变一下主角吧：羊非常娇贵，经不起长途运输，所以你放进去一条狼，羊群十分紧张，左冲右突，四处躲避，加速跑动，这样羊的问题就迎刃而解——
一车死羊。
鲶鱼的事，假的无疑。
有个美洲豹的故事。说美洲豹是非常高傲的动物，捕猎最多只尝试7次。如果7次捕猎都没能成功，就高傲地直视失败，气呼呼地不再捕猎，直到饿死。——正解是：如果7次捕猎都没成功，美洲豹就叫外卖。
有个海鸟叼树枝的故事。说一种海鸟常年在海上飞，但是羽毛不防水。那么它飞累了怎么办呢？说这种鸟会选择一根长短粗细合适的小树枝，叼着它飞，累了就把树枝扔在海里，站在这根树枝上休息。——正解是：那只海鸟其实要把树枝插进编故事人的脑子里。
有个温水煮青蛙的故事。不说了，都知道。——正解是：应该换成温水煮螃蟹，活螃蟹只能用凉水煮，然后开着火，让水慢慢变热，变成温水，直到最后杀死螃蟹。没啥理由，为了煮出来好看，因为开水煮螃蟹，是会断腿的，几个圆盖子一锅腿，那是什么场面。
有个老鹰拔毛的故事。说老鹰过一段时间就用嘴把毛拔掉，然后把爪子磨掉，鸟喙撞碎，虽然很痛苦，但是等到新的爪子和喙长出来，又是锋利的了。所以人也要在痛苦中磨炼和进步。——正解是：去过肉菜市场的人都知道里面摆的鸡多么进步。
还有类似的故事，能说一箩筐，欢迎补充。
为什么这种东西能流传呢？因为人是从众的动物，本能地骨子里有一种从众取向，人家都说，自己也说，久而久之，越传越广。
还因为这些故事的主角是动物。动物不会说话，不能反驳，没有权利，没有律师，你说对了你装 逼成功，你说错了也不需要损害赔偿。因此，我们大可以胡编瞎说，甚至造谣诽谤。君不见，不是有电影《大白鲨》么，不是有《狂蟒之灾》么，不是又出了什么《鲨海》么？把看电影的人吓得一愣愣的，以为鲨鱼和蟒蛇就是那样。人类和动物到底有什么区别？人能造谣。
直到那些被造谣的动物灭绝，成了传奇，那瞎说起来就更方便了，比如恐龙，《失落的世界》可以永远“失落”下去。
下次再见到任何造谣活生生的现存动物的东西，请大家吐一口唾沫并走开。
