"Nice looking!" On May 4, Dai Jianming, a New Farmer of the post-95s', got up early in the Ningbo Fanghua Agricultural Machinery Professional Cooperative in the Shenxi Village, Jishigang Town, and went straight to the greenhouse to check the growth of crayfish seedlings in the "Symbiosis of Rice and Fish". "This batch of crayfish seedlings was released in early April and is still in the rough stage. After one month, they can be released into the outdoor field ditch to support the growth of single-season rice this year." Dai Jianming said.

Dai Jianming, born in 1998, studied architecture during his university years. After graduation, he returned to his hometown and established the Ningbo Fanghua Agricultural Machinery Service Co., Ltd. and began to engage in agricultural activities such as spring plowing, early rice sowing, wheat harvesting, straw harvesting, bundling and recycling, etc., and to provide farmers with agricultural machinery use and maintenance services. In 2020, when learning the promotion of and researches for a new path of raising crayfish in rice fields in the district, Dai Jianming keenly sensed the business opportunity and decisively tried such kind of farming. "I am quite interested in agricultural layout and have been influenced by it since childhood, therefore, I returned to my hometown to devote myself to agriculture as soon as I graduated, and I also want to do some innovative things and make some achievements."

It is learnt that the so-called "Symbiosis of Rice and Fish" refers to the symbiosis between rice and fish. "Rice" refers to rice, while "fish" refers to crayfish. Crayfish weed and loosen the soil in rice fields, while rice fields provide food for crayfish. The two coexist and promote each other in the fields. Over the past two years, Dai Jianming has managed 390 acres of organic cycling ecological farming and breeding fields integrating rice and crayfish. He has exerted a lot of effort to make crayfish live well in these fields and make rice grow well.


"Crayfish are particularly particular about their diet, very sensitive to water quality, and are brave and aggressive. It is not easy to raise crayfish to be fat and strong, thus each acre of field can only accommodate a maximum of 2.000 crayfish." Dai Jianming told the reporters about his breeding experience, "crayfish breeding should be reasonably coordinated with the sowing time of single cropping rice. The crayfish seedlings should be placed in the greenhouse for cultivation when they are in the standard thick section, and the temperature in the greenhouse should be maintained between 26 and 36 degrees. During this period, it is also necessary not to stop the oxygen pipe for oxygen delivery to avoid mass death of vulnerable crayfish seedlings. After being placed in the outdoor field ditch, it is also necessary to monitor the water quality, diseases and pests."

During the breeding process, Dai Jianming also adopted a UAV feeding method, which not only saved manpower but also greatly improved the feeding efficiency, allowing the red crayfish to eat suitable feed at different growth stages. However, the process of breeding is not that smooth. "We have also encountered typhoons before, but fortunately, we have insurance policies that help reduce losses. We are also constantly summarizing our experience in breeding methods." Dai Jianming said proudly, "after these years of practice, the crayfish we are raising now have a high meat yield, high meat quality, and delicious taste. The annual production capacity of rice and wheat per mu has reached nearly 800 kilograms, with good quality and favorable taste. The total annual output value is expected to exceed 6 million yuan."

In recent years, Dai Jianming has never stopped moving forward, learning new technologies, introducing new machines, traveling to various places to learn from excellent experiences of others, and bringing them back to his hometown. "The exploration of "Symbiosis of Rice and Fish" still has a long and arduous way to go." Standing on the field, Dai Jianming is full of confidence and determination for the future.
