Norwegians love to eat sardines, especially live fish. Live fish are much more expensive than dead fish in the market, so fishermen always try to find a way to get the sardines back to the fishing port alive. However, after all the efforts, most of the sardines still died of suffocation in the middle. But there is one fishing boat that always gets most of the sardines back to the fishing port alive. The captain kept the secret tightly until his death, and the mystery was not revealed. It turned out that the captain had put a catfish in a fish tank filled with sardines. After the catfish enter the fish tank, they swim around due to the unfamiliar environment. The sardines were very nervous when they saw the catfish, rushing left and right, dodging in all directions, and accelerating their swimming. In this way, the lack of oxygen of the sardines is solved, and they will not die, and they can return to the fishing port alive.
