Why has "fish farming in rice fields" been so popular in the past, but has become less and less common in recent years?

Paddy field fish farming used to be very popular, but in recent years it has been rarely heard of, mainly because there are many problems involved in rice field fish farming. First of all, taking care of both is a technical job, and many people are doing it. There is a shortcoming in this area. Moreover, rice cultivation and fish farming are in conflict with each other. If they are not resolved well, neither will work. The breeding of rice and fish is limited by the site, and drought and floods need to be considered. Therefore, as people's living conditions improve, many people choose to either grow rice or breed fish.

Raising fish in rice fields seems simple, but in fact it is very complicated. It requires very high requirements for the ditch, which must not be too deep or too shallow. If it is too shallow there is no water, and if it is too deep it is not good for the rice. Many of today's growers only have one of these technologies, and not many people have truly mastered the technology of raising fish in rice fields. Many people have tried, but ended in failure, and finally gave up. As time goes by, fewer and fewer people.

It is difficult to achieve both rice and fish harvests when raising fish in rice fields. Because fish and rice will conflict during the planting process. During the rice production process, pesticides need to be sprayed to control pests and diseases. However, these pesticides can cause harm to fish and increase fish mortality. Therefore, sometimes if rice is taken into consideration, fish cannot be taken into consideration, and the two cannot be used for a good harvest. And raising fish in rice fields is also very time-consuming and energy-consuming. The effort is not proportional to the gain, so many people choose to give up.

If you want to breed fish in rice fields, there are requirements for the location of the rice fields. You need to choose a place close to water. Only in this way can the fish have sufficient water sources and not die from lack of water in dry weather. But being close to water also has its dangers. When there is a flood, the rice will be flooded. Compared with the income from rice, fish is not yet the main source of income, so when comparing the two, farmers generally choose the main source of income. And now many people have chosen to go out to work, and the number of people planting rice fields is also decreasing. Even those who plant rice fields will not put more energy into this more laborious model of rice and fish farming.
