Fishing: There are many small fish in the ditch beside the rice field. How did they come from?

Originally, this kind of fish has low requirements for water quality, but it can be clean and smelly, and it is also found in Qingshui District. So some animals, such as birds, take some fish eggs with them when drinking water. When they arrive at another place, these little things can grow without any natural enemies.

There is also a guess that it flowed in from the outside. Most of the water areas are interconnected, and you may see that they are impassable, but there may be underground water flows that are interconnected. But because those fish are not interested in sewage and can't survive, only what I call "Egyptian" fish can survive.

Generally speaking, the ditches in rural areas are connected, after all, the cultivation of crops needs timely watering. During the rice planting season, basically all ditches are filled with water. In this case, fish like to swim against the current, and then they flow into various Tang kings. Generally, the gutter is the favorite of soft-shelled turtle and catfish.

Because in the breeding season, the whole river and pond are full of sperm, eggs and fertilized eggs of various fish. You can't see them, but the number is amazing. When some birds move on the water, these "little guys" will touch the birds. If birds play here and come to a pond with only water and no fish, they are likely to find heaven for fertilized eggs.
