Extended information:

The pangolin has become a must-have species for pond fish farming in the south because it has the advantages of a wide range of feed sources, adaptability to fatter water environments, greater disease resistance, and higher group production. The pangolin can eat the algae and organic debris under the water, so it is also known as the "scavenger" of the pond, and fertilization of the pond is even more important to raise pangolins.

The fish are fed differently, so mixing them with other fish is a great way to increase production. Once upon a time, only the use of natural fish fry for rearing, Xijiang produced 70% of the fish fry is pangolin fry, now can be artificially bred.
