Chapter 2333

If the rice had insects, the fish fry would also eat these insects. This was a method that served several purposes, could greatly reduce the amount of pesticide used, and truly achieve the goal of ecological agriculture.

This technology was of course taught to the farmers by several experts. When to put fish fry and how big the fish fry to put were all strictly stipulated. If put too early, the fish fry would eat the rice seedlings, and if put too late, the weeds would grow too high and too old, and the fish would not eat them.

Of course, rice field fish farming was far from as simple as directly putting fish fry into the rice field. In the rice field, it was also necessary to dig fish collection ditches and pits to ensure that the fish also had a place to survive when drying the field. In addition, there were many details that needed attention. Without the guidance of experts, it was not so easy for rice field fish farming to succeed.

Farmers in Chongjin County established cooperatives. Farmers who joined the cooperatives could share resources, share technology, and share channels, which could greatly strengthen their ability to avoid risks and maximize their interests.

The high-quality rice produced here would mostly be sold to the Luo Group's agricultural product processing factory. After deep processing and fine processing, it would be sold to big cities and even abroad.

And the fish raised in the rice field could also add an income for the farmers. According to Professor Rao, as long as the field management was proper, the yield of fish per mu of rice field could reach about one hundred jin. These fish were not raised with feed, but grew by eating grass and insects, so the taste was quite good, and they could also sell for a good price.

Fishermen living by Yanglan Lake also established cooperatives and started cage culture. They raised various economic fish and crabs in the cages. These were aquatic products with very high economic value. As long as the management was proper, the economic value produced by one mu of water surface would far exceed one mu of land.

Cage culture was also not so simple. How deep and how big the cages were were all particular. And how to fix the cages also required technology because Yanglan Lake water was different from ordinary small lakes. Yanglan Lake water was very deep, with the deepest place reaching dozens of meters. It was very difficult to fix the cages.

Therefore, the technology of several experts and their students played an important role again at this time. They taught the fishermen by the lake hand in hand to put down cages one by one. These cages carried the fishermen's hope and sank into the water one by one.

Cage culture had many benefits, such as high and stable yield. And because fish and crabs and other aquatic products were raised in cages, they would not touch the soil at the bottom of the lake, so the quality was also very good. In short, cage culture was a very good way to get rich.

After the fish species were put into the cages, how to manage them was also a work with a lot of technical content. If the management was not good, the fish would also easily get sick. Therefore, the experts and their students also taught the cage management technology to the fishermen and technicians hand in hand.

Chongjin County's ecological agriculture slowly started from this time.
