挪威一家远洋捕捞公司发现存放在水槽中的沙丁鱼不喜欢游动，而半死不活的鱼和冷冻的鱼一样丧失了鲜味。直到几年后，他们才解决了这个难题，办法其实很简单：在每个水槽中放进一条鲶鱼，原本懒洋洋的沙丁鱼一看见鲶鱼，立刻感到威胁，为避免被鲶鱼吃掉而迅速游动起来，于是整? An offshore fishing company in Norway found that sardines kept in sinks did not like to swim, and half-lived fish lost the same flavor as frozen fish. Only a few years later did they solve this problem. The solution was actually very simple: Put a squid in each sink. Once the lazy sardines saw the squid, they immediately felt threatened and quickly swam to avoid being eaten by the squid. When you get up, you get the whole thing?
