Raise 10000 catties fish, 100 square water =10 mu! This kind of rich breeding mode "walk" into Guangxi
More than 100 water to raise 10 mu yield, "runway fish" and bring wealth to new places
"Runway fish farming", as one of the "nine ecological breeding models" promoted by the Ministry of Agriculture and Rural Affairs, has achieved gratifying results in the important period of fishery and aquaculture transformation. Jiangsu, Zhejiang and other regions as representatives of the continuous introduction and trial of the fish farming model, has achieved good ecological and economic benefits. The yield of 10 mu in the past can now be achieved on the surface of more than 100 square meters, and 0 discharge of pond tail water is realized. By introducing this model, Guangxi Sanjiang not only improves the local aquaculture efficiency, but also develops it into a modern aquaculture demonstration base integrating production and leisure tourism. The "runway fish" ran out of the rich "acceleration." The author had the honor to interview sanjiang County, understand the local "runway fish" some trends.
Why choose fenshui village "runway fish" project? Transform into "runway raise fish" whether need what condition?
In October 2020 in Guangxi aquaculture breeding center, county agriculture and rural bureau, county bureau of science, industry and Trade experts visit Fenshui village survey, Fenshui village is located in the most northern village of Sanjiang County, rich water, water quality is very good, and Fenshui village has more than 200 years of traditional fish farming habits, almost every family have fish ponds. And there is fenshui Village college students pioneer park, organized a group of college students engaged in product breeding, packaging and brand promotion, the whole industry chain is relatively mature. After expert research decision, "runway fish" project settled in Fenshui Village, help rural revitalization.
What is the current scale of the project?
At present, the project of college students pioneer park area fish pond transformation, pond about 3 mu of water, the construction of a total of two "running groove", rectangular, each groove accounted for more than 100 square meters of water, 26 meters long, 5 meters wide. Although only one fish pond has been modified, it is only used as a pilot project. The results so far have been human, environmentally friendly and productive. Fenshui village is rich in water resources, and almost every family raises fish. Subsequently, we will gradually promote this model to the outside, and strive to make every family on the road to wealth.
What are the free range varieties? Are there restrictions on the breed to be farmed?
Mountain carp and local gRASs carp are the main breeding, theoretically speaking, "runway fish" suitable for a variety of species, perch, ð fish, yellow catfish, gRASs carp, carp, etc However, limited by geographical conditions and technical conditions, the breeding varieties of the "runway breeding" project in the park are still limited to a certain extent. I believe that with the in-depth practice of this model, coupled with the help of experts, will continue to introduce new varieties.
How far is the project going? What were the results? How much can be produced?
The project started construction in December 2020, and by May 2021, it has been invested and put into operation with remarkable results. Each tank has more than 100 square meters of surface aquaculture output can reach more than 10,000 jin. In the past, but this is 10 acres of fish pond output! Hard to imagine, if this kind of technology if applied to every household, can bring much economic benefits for the villagers! And it is still in the early stage, facilities and experience are not perfect. With the accumulation of breeding experience, it is believed that the yield will be improved.
As a high-density intensive farming model, "runway fish farming" requires certain technical content. Where does our technology rely on? Is it easy to master?
Aquaculture technology relies on guangxi aquatic breeding center, county agriculture and Rural bureau aquatic station. After the experts' careful training, on-site guidance, problem tracking, etc., the breeding technicians have basically mastered the project technology. Since this model transforms traditional pond "free-range" fish into "captive" fish, it is easier to manage and catch. According to the expert instructions of water aquaculture and tail water "0" discharge treatment, not only environmental protection, but also let the aquaculture fish more healthy, not easy to get sick. Fish eat food every day as if in "exercise fitness".
How to achieve zero tail water discharge?
At present, this project may not be able to achieve a complete zero discharge. The tail water of the "runway fish farming" plan is discharged to the paddy field first, and then passes through the self-purification system of the outer pond itself, including some algae, aquatic plants and filterfeeding fish such as silver carp, to achieve the effect of zero discharge. However, the equipment is not perfect in the initial stage of the project, and the tail water will be purified through multi-stage paddy fields and then discharged into rivers. Tail water discharge index is fully in line with the national requirements, absolute safety and environmental protection.
What difficulties need to be solved immediately?
At present, the urgent problem to be solved is the strengthening of the mode and the improvement of the equipment. At present, the feeding mode and feeding management still need to invest a lot of energy. Tail water discharge has not reached the complete recycling. In order to more effectively respond to the national policy of sustainable development and the goal of rural revitalization, these problems are urgently needed.
Is it expensive to build and run? How replicable is it?
It's cheap to build and reproducible, and although the pond renovation cost some money, the economic benefits of a significant increase in production are dwarfed by these. And this is basically a one-time investment, but the fish are raised every year, so it's profitable in any case. Moreover, this model of fish farming is green, healthy, more in line with food safety standards, and more popular with the public.
What is the significance of "runway fish farming" here? What are the benefits? How about the promotion to the surrounding area?
Runway breeding technology is a new efficient breeding method developed in recent years, which can be high-density breeding and has good economic and social benefits. Set machine, electricity, automation, biological engineering technology as a whole, with ecological environmental protection, pollution-free, automation, information and other advantages of modern agriculture. It is hoped that the successful experiment of racetrack fish farming can be extended to surrounding or further villages with conditions and lead more villagers to become rich.
How do you prepare for the next step?
In the next step, we plan to increase the investment in "runway fish farming" and adopt the "company + cooperative + farmer" experience model to promote and develop this industry. To build the industry into an industrial chain, from breeding to processing to promotion of finished products, to make their own characteristics. At the same time, we insist on providing opportunities for college students to help them start their own businesses and find jobs.
What do you think is the future trend of facility fisheries?
"Runway fish farming" has low investment cost, easy to learn, remote control, good benefit and promising development trend. In the future, it may become the dominant mode of fish farming.
