Perch climbing is a collective activity in spring and early summer, ranging from six or seven to more than a dozen. Generally, a large group is full of relatively large male fish.

This kind of fish can climb trees and often climb palm trees on the shore to suck juice. This discovery caused a sensation in the western society at that time. Because this fish sometimes migrates ashore in rainy days, it is often caught by birds, such as crows and kites by the pond. These birds take the fish away and put them on the treetops and branches. This kind of fish often appears in the crown of trees. It is found that it sometimes hangs on trees and sometimes stays in puddles between palm trees with water, so people think that this fish will migrate and climb trees.

Climbing perch has a variety of feeding habits, but most of them feed on various aquatic insects and shrimps, and they also like flying insects falling into the water. Sometimes it attacks other fish, but generally it is not for eating. Sometimes it will eat our bait, especially if it smells fishy. Young corn is also good at catching mountain crucian carp. Once I caught grass carp with corn in Baipenzhu, and caught dozens of Parthenocissus tricuspidata.

The word "perch" behind the climbing perch indicates that it is a perch, and the word "perch" in front indicates that it can really climb. It also has many "nicknames" that sound very powerful: cross-mountain crucian carp, Hainan woman and so on. That is to say, it may really cross the mountains. Brother Li once caught a bass and left it on the shore for several hours without dying (under the scorching sun). No matter where you put it, he can accurately find the nearest water source and climb into the water like a reptile. He has also seen bass climb from one pond to another many times.
