Catfish effect means that catfish not only stirs the living environment of small fish, but also activates the survival ability of small fish. Catfish effect is a means or measure to stimulate some enterprises to get active and participate in the competition in the market, thus activating enterprises in the same industry in the market.

For "fishermen", the catfish effect lies in the application of incentives. Fishermen use catfish as an incentive to encourage sardines to swim constantly to ensure that sardines are alive, so as to get the maximum benefit. In enterprise management, managers also need to introduce catfish talents in order to achieve the management goal, so as to change the situation that enterprises are relatively stagnant.

A long time ago, people living in Norway loved sardines very much, and many fishermen caught sardines to earn their living expenses. In fact, the food made from fresh sardines tastes better and is more popular with customers, so fishermen hope to bring back live fish to get higher profits. However, it is difficult to guarantee the survival rate of sardines because the fish on the ship will die of hypoxia and suffocation, which has puzzled fishermen for a long time.

Curiously, among many fishing boats, one boat can bring fresh sardines to the shore, and no one has found out what measures they have taken to ensure the freshness of the fish. The mystery was revealed after the captain's death. The captain put a catfish in a tank full of sardines, and it swam back and forth uneasily when it entered a strange environment.

Because catfish is a kind of fish-eating species, when sardines see catfish rampaging in the water, they will go into a state of alert for fear of being eaten and swim back and forth in the sink, thus solving the problem of suffocation of sardines, so the captain can bring back fresh sardines.
