Norwegians used to eat sardines a long time ago, especially sardines in live fish markets, which are much more expensive than live fish, but many fishermen racked their brains and did not guarantee that sardines would return to the fishing port alive. Later, it was found that after placing a catfish in a fish tank filled with sardines, it was possible to bring back fresh sardines. It turned out that after the catfish entered the fish box, due to the strangeness of the environment, it swam around, and the sardines saw that they were very nervous, and they also followed the left and right rushes to avoid accelerating the swimming. As a result, sardines bounced back to the fishing port alive.
