What are the common misconceptions about rice field eel farming?

In the process of rice field eel farming, some farmers take certain things for granted that are actually wrong, mainly shown as: the less pond water the better, the more manure the better, frequently changing feed, etc.
The less pond water the better
If rice field eels frequently swim to the water surface to breathe, affecting normal growth, it is mostly caused by the pond water being too deep. For pond-raised rice field eels, the water depth should preferably be around 20 cm to 30 cm, while for cage-raised rice field eels, the aquatic plants should fill the entire cage as much as possible, so as to provide good habitat and breathing conditions for the rice field eels.
The more manure the better
Applying manure very easily spoils the water quality and induces diseases in rice field eels.
Frequently changing feed
Rice field eels have a certain fixed preference for the bait they eat; suddenly changing the type of bait will cause the rice field eels to refuse to eat, affecting normal life and growth. If the bait really needs to be changed, the proportion of the original bait should be gradually reduced while increasing the proportion of the new bait to make the adjustment.
