【Catfish Effect】
🐟 Norwegians love to eat sardines, especially live fish, which are much more expensive on the market than dead fish, but sardines die quickly if there is no stimulation and activity after fishing.
Every time Norwegian fishermen return from the sea, in order not to let the fish die on the way
Go, put a few ridge fish in the sardines' fish compartment to pick them up
Friction and disputes with sardines make a large number of sardines swim constantly in tension. The result was not only to prevent the sardines from dying due to room rest, but also to ensure that they arrived alive in port, a phenomenon that came to be known as the "catfish effect".
