Guangrao County vigorously develops facility fisheries, builds greenhouses as standardized breeding workshops, and is equipped with water quality treatment pools and intelligent aquaculture and other related supporting facilities, so that vannamei shrimp can live in the "greenhouse".
In the greenhouse of Qunhai Family Farm in Chenguan Town, the square shrimp pond is rippling with blue waves, and the person in charge, Zhang Haiqun, is checking the growth of the shrimp seedlings that have just been put in.
"Today, we have invested 4 million shrimp seedlings in the standard coarse shed, this shrimp seedling has been desalined from the seedling factory for ten days, and now it is the third day to enter the standard coarse pond, and the shrimp seedlings are more adapted to the water temperature, water quality and salinity of the standard coarse pool, and the survival rate is relatively high." Zhang Haiqun, head of Qunhai Family Farm in Chenguan Town, said.
Qunhai Family Farm in Chenguan Town has 80 acres of pit ponds, 4 indoor shrimp seedling standard coarse ponds, equipped with aeration equipment, oxygenation and other breeding facilities, relying on the unique saline-alkali land advantages, to carry out factory intensive breeding of vannamei shrimp.
"We have a shed yield of about 2,000 pounds per mu, a year of income of about 40,000 yuan, saline-alkali land contains a large number of trace elements, very suitable for the growth of vannamei shrimp, the shrimp that grow into a large size and taste more delicious, especially popular in the market, the surrounding farmers are from our side into the seedlings." Zhang Haiqun, head of Qunhai Family Farm in Chenguan Town, introduced.

This year, Chenguan Town Qunhai Family Farm continues to adopt the "135" breeding model of Penaeus vannamei shrimp, that is, Penaeus vannamei shrimp is bred in the desalination workshop for about 10 days, and then after 30 days of temporary greenhouse culture, and finally about 50 days of breeding in the outer pond can be listed, realizing the northern natural pond shrimp farming two crops a year.
"If you put in shrimp seedlings now, you can go on the market in 3 months, which is 1 month earlier than the shrimp farmed in the big pond, which can effectively avoid the rainstorm weather and disease outbreak period that are prone to occur in August, and the yield and efficiency will be greatly improved." Zhang Haiqun said.
Guangrao County gives full play to the advantages of resources, and actively explores new technologies and new models for the development of fisheries, up to now, the county's sea and freshwater aquaculture area of 90,000 acres, the total output of aquatic products is 58,000 tons, and the total output value of marine fisheries is 590 million yuan.
"Continue to introduce new varieties and new models, promote the transformation and upgrading of fisheries, and at the same time increase investment attraction, strengthen cooperation with scientific research institutions, and promote the ecological industrial structure and high-quality economic form." Liu Qun, director of the Fishery Technology Extension Service Office of the County Agricultural and Rural Comprehensive Service Center, said.
