The first batch of fry is coming, and everyone hurries up to finish the finishing work and debug the equipment in Zone 1. At noon on February 22, Zhang Chuanxin, the leader in charge of the factory fishery breeding demonstration project in Gaofeng Town, Gui'an New District, Guizhou Modern Fishery Group, came to the project site to guide the final finishing work of the project.
The reporter saw at the scene that there are a number of blue circular fish ponds in each plant in the breeding area, several white pipes stretching into the fish pond, there is no water in the pond for the time being, and several workers are cleaning the fish pond and surrounding facilities and roads. "The size of the fish pond is designed according to the actual topography and breeding needs. Zhang Chuanxin said that the project has three districts, covering an area of about 36 acres, and there are currently eight 7-meter diameters in one area5 m deep fish ponds, 12 x 6 m diameter, 15 meters deep fish ponds, with a total of 98 fish ponds in three districts.
Zhang Chuanxin introduced that the current plan is to focus on the cultivation of sea bass, and will consider adding mandarin fish and other species in the later stage. The first district is expected to usher in the first batch of fish fry in three days, and the second and third districts will also be put into use in the near future. After all three areas are put into operation, it can produce 500,000 kilograms of sea bass per year.
The meat of sea bass is tender and popular among consumers. Guizhou is rich in water resources and has always had a tradition of cultivating various kinds of fish, but the cage culture method used in rivers and lakes in the past not only has low breeding density and poor economic benefits, but also causes great pollution to the environment. Zhang Chuanxin said.
In order to protect the ecological environment of the waters, in 2018, the whole province banned cage farming, so that aquaculture got rid of the passive situation of "relying on water draft", and large-scale factory farming was widely used due to high breeding density, good economic benefits and zero pollution.
Factory fishery farming is equipped with a controllable water environment intelligent control fishery breeding system, which can supply oxygen to all fish ponds, and can automatically complete water circulation and waste cleaning, which greatly improves production. Once in natural waters, only 05 to 1 kg of sea bass, while factory farming, which can raise up to 50 kg of sea bass per cubic meter of water, increases production by 50 to 100 times. Zhang Chuanxin said.
The reporter saw in another factory that several workers were debugging a number of large square water tanks. Zhang Chuanxin introduced that the plant is a water treatment workshop, using small, medium and large three-layer water circulation, and the "small circulation" of the workshop is carried out 24 hours a day. The large water tank that the workers are debugging is used to process manure and bait residues in the "small circulation" to ensure a safe and clean environment for the growth of sea bass; The "middle circulation" carried out by the entire breeding base will re-treat the aquaculture tail water and return it to the breeding area for reuse; The water that needs to be replenished due to evaporation and other losses is replenished from the external "big circulation". In this way, the three-layer water cycle farming method greatly reduces pollution and has very little water loss.
The project also set up an exhibition hall in the office area, and specially designed independent visiting routes and pedestrian passages, which were separated from the vehicle and cargo channels, laying the foundation for the subsequent promotion of the integration of agriculture and tourism.
In recent years, Guiyang Gui'an has continued to improve the production and supply capacity of aquatic products and promote the high-quality development of ecological fisheries. In January this year, the Guiyang Municipal Bureau of Agriculture and Rural Affairs issued the "2024 Guiyang Gui'an Ecological Fishery New Aquatic Product Output of 1 Million Jin Work Plan", which clearly will promote advanced breeding technology, introduce excellent breeding varieties, and enhance economic benefits.
The factory fishery breeding demonstration project in Gaofeng Town, Gui'an New District, started construction in November last year, and is also one of the projects involved in the plan. According to the plan, Guiyang Gui'an will build or upgrade 5 ecological fishery bases in Xinbao Township, Wudang District, Xishan Town, Luwo Town, Xifeng County, Guiao Industrial Park and Gaofeng Town, Gui'an New District.
According to the relevant person in charge of Guiyang Agriculture and Rural Bureau, this year, Guiyang Gui'an will make efforts in project construction, main body cultivation, seed industry development, variety optimization, scientific and technological services, and safe production to promote the high-quality development of the ecological fishery industry and help Guiyang Gui'an agricultural and rural modernization and rural industry revitalization.
