Bend down to lower the net, the net stays in the water for a while, and quickly scoops it up, and the shrimp are all in it. This is Linze County, Zhangye City, Gansu Province, located in the middle of the Hexi Corridor, which is located inland. In 2022, the strontium-rich Penaeus vannamei land-based circulating water intelligent breeding base landed in Baizhai Village, Yanuan Town, Linze County, and the trial breeding was successful in May of the following year. Since the project was completed and put into operation, it has sold tens of thousands of catties of fresh shrimp.
The water of the Heihe River flows through Linze County, forming lakes and swamps, and the conditions for aquatic product breeding are unique, but seafood farming is rare. "The key is water quality and temperature. Ma Guibin, head of the Fengsen Breeding Farmers Cooperative in Zhangye City, said that tropical seafood farming in the alpine and high-altitude inland areas relies on advanced technology and facilities.
Walking into the shrimp greenhouse, the warmth greets you. Ma Guibin introduced that in addition to relying on heating equipment, there are also steel frame insulation greenhouses with two-layer greenhouse film to achieve energy conservation and efficiency.
We add salt, minerals, trace elements, etc., to create 'artificial seawater'. Pointing to the water circulation system all over the greenhouse, Ma Guibin said that the water used for shrimp farming is biodegradable, physically filtered, and reused for reuse, "Compared with traditional earthen pond shrimp farming, the same output can save about 95% of water." ”
The Spring Festival is approaching, and Yang Juxiang, a villager who works in the breeding base, is particularly concerned, "The Spring Festival fresh shrimp has been pre-sold for thousands of catties, and now is the critical period for cultivation." With children to take care of, she used to have to do odd jobs and farm work. "Now I work stably at home, with a monthly salary of more than 4,500 yuan. Yang Juxiang said.
The village has a low terrain and high water level, and the water contains a large amount of alkali, which forms a large area of saline-alkali land after evaporation. Qi Guoji, secretary of the general party branch and director of the village committee of Baizhai Village, introduced, "Now the saline-alkali land has become a cornucopia. Last year, the collective income of the village exceeded 120,000 yuan, and nearly 40% came from the shrimp farming base. ”
Taking advantage of resources, we cultivate and support aquaculture as a characteristic industry for rural economic development. Lin Duowei, Secretary of the Party Group and Director of the Linze County Agriculture and Rural Bureau, said that at present, the breeding base represented by Baizhai Village has driven the county to increase the aquaculture area by more than 500 acres every year.
