Hongyun Company, located in Jintangji Village, Shenlun Town, was invested and built by Shanghai Hongyi Investment Management Co., Ltd., relying on the joint efforts of Shanghai Academy of Agricultural Sciences and Shanghai Ocean University, mainly focusing on mandarin fish and California bass culture, and building an ecological and environmental protection demonstration base for cold-water fish culture.
Walking into Hongyun Fishery Workshop, the environment is clean and tidy, and there are many aquaculture ponds. The dense mandarin fish and California bass are swimming happily in the pond. They sometimes surface and sometimes dive into the bottom of the pond, and the whole pond is full of vitality and fun.
"Circulating aquaculture is one of the modes of industrial aquaculture, which is to use modern equipment and technical means to make aquatic products in a relatively controlled living environment and in a high-intensity production state.
From the breeding of fish seedlings to the breeding of fish, it is necessary to go through the links of brown hatching pond, splash pond, black pond and standard seedling box (breeding pond), and finally the adult fish can be sold at about 1 kg.
Xiao Weng, a staff member who graduated from aquatic products major, said that in addition to good water quality, circulating aquaculture has three major characteristics: first, it covers a small area and has a high breeding density; Second, the survival rate of fish is high; Third, the predation speed of fish in the pool is accelerated, and the growth cycle is also accelerated.
Under the traditional culture mode, it takes 10 to 12 months for a fry to grow into a 2 kg commercial fish. In circulating water culture, the growth period of fish can be advanced by 3 to 6 months.
"Circulating aquaculture is equivalent to artificially restoring an ecological environment similar to big lake aquaculture for fish, so the fish is delicious and tastes good.
Xiao Gong, a technician in charge of aquaculture management, said that the so-called circulating aquaculture is simply to reuse the water cycle of fish farming, so as to achieve the effects of ecology, environmental protection, water saving and efficiency improvement.
This culture method does not need the traditional running water facilities, and each fish pond is a closed circulating water system, that is, each fish pond has a water delivery pipeline, a drainage pipeline and a manure pipeline, wherein the drainage pipeline is connected with the water treatment system at one end of the workshop, and the water in the pond is continuously transported to the water treatment system for treatment, and then the treated water is returned to the fish pond to form the recycling of the cultured water.
"It is precisely because we can artificially control the environment that the harvest and listing of mandarin fish and California bass here are not affected by seasons and climate, and can be supplied all year round.
"
"Compared with the main aquaculture species in xinghua city, the mandarin fish and California bass cultured by our company have the advantages of high economic benefit and short aquaculture cycle.
We have actively developed order fishery by improving the culture technology of mandarin fish, and the price of mandarin fish pond mouth is as high as 70 yuan per catty, which is much higher than the market price.
According to Sun Hong, the boss of the company, from 2002 1 year1to August, more than 100,000 bass and mandarin fish fry were sold in the company's nursery area, with an output value of more than 3 million yuan.
At present, the company has 27 college graduates majoring in aquatic products and animals, and their annual salary is around100000 yuan.
In addition, the company also attracted more than 40 farmers from Jintangji Village, Fansheng Village and other villages to work to earn money, with a monthly salary of more than 4,000 yuan.
"Here, I am responsible for assisting in the on-site management and cleaning of garbage and sundries. I earn 4,500 yuan a month, and my income is much stronger than that of single farming in the past!" The old Xu of Jintangji Village said happily.
The reporter learned that Hongyun Fishery Co., Ltd. has completed an investment of about10.30 billion yuan, transferred cultivated land 1800 mu, and the water surface of the river pond is about 1000 mu. It has built three special breeding sheds and fish breeding sheds, covering an area of about 40 mu and 70 mu of open-air breeding fish ponds.
"Now the production situation is good, and it can produce about 1 00000 fish fry every day. The next step will be to further expand the production scale, and strive to sell1100 million this year, and strive to accept more employed people to work here to earn money.
"Sun Hong finally said.
