To rivers, lakes and seas for food, modern fisheries transformation

Author:


It is a critical period of fishery production, and in Marine aquaculture bases such as Fujian and Guangxi, fishing boats are fully loaded with fish. In Jiangsu, Hunan and other areas, rice and shrimp were used in the fields, and the first batch of shrimp seedlings had been released. In Hubei, fishermen who have retired from fishing along the Yangtze River have been reemployed, and modern fisheries such as factory farming have flourished.

This year, the central No. 1 document proposed to build a diversified food supply system. As an important source of high-quality protein, rich and diverse aquatic products are an important part of the "basket". To rivers, lakes and seas for food, how do modern fisheries maintain production and supply? How does aquaculture increase fishermen's income and green industry? The reporter conducted an interview.

Strengthen the advantages of the characteristics, extend the industrial chain, fishermen more and more money

Guangxi Fangchenggang City Bailong Pearl Bay sea national Marine pasture demonstration area, boundless expanse of green waves, a breeding nets scattered. In April, the water temperature here is stable at more than 18 degrees Celsius, entering the seedling season.

In the pearl Bay Golden Pomfret culture industry development base of Fangcheng District, farmer Chen Zhongqi is busy putting fish fry: "These years, the fame of golden pomfret is getting louder and louder, and the breeding is getting more and more vigorous!" Since 2020, Chen Zhongqi has farmed golden pomfret in the cooperative, and after mastering the technology, he raised 4,000 tail by himself last year, with a net income of 14,400 yuan, and is ready to expand the scale again this year.

"Golden pomfret is our geographical indication agricultural product here, with fresh taste, tender meat and a short growth cycle." Chen Yuansheng, deputy director of the Agriculture and Rural Bureau of the Fangcheng District, said that the district has made every effort to create regional public brands through the "six unified" mechanism such as seedling supply, management and sales, so that the "gold content" of the golden pomfret industry is getting higher and higher.

In Pearl Bay, Fangcheng District, there have been 9 large-scale aquaculture enterprises settled, the total output value of aquaculture reached 1 billion yuan, forming a advantageous characteristic industrial cluster. Chen Yuansheng said that some farming projects adopt the model of "leading enterprises + village-level collective economic organizations + farmers", driving local farmers to increase their incomes and providing more than 2,000 jobs.

At present, more than 300 Marine ranches have been built across the country, and more than 50 million cubic meters of fish reefs have been released. Marine ranches have brought remarkable economic, ecological and social benefits.

Characteristic aquatic products "one after another", the industrial chain is getting longer and longer. At the Beibu Gulf International Fresh Cold chain Logistics Park, located on Yushitan Avenue in Fangchenggang's high-tech zone, staff are quarantining seafood. "The park integrates processing, distribution, refrigeration and trading, giving full play to the advantages of Fangchenggang fresh food import infrastructure resources." Park related person in charge Huang Zhiyong said. Fangchenggang accelerated the construction of a national fishing port economic zone, and initially formed a new pattern of integrated development of fish deep-processing and recreational fishery industries.

Characteristic aquaculture continues to inject new momentum into rural revitalization. In Suichuan County, Jiangxi Province, Bizhou town, Baishui village eel farming base, the person in charge of Chen Shuqiang introduced: "Eel farming technology content is high, good efficiency, the base specially hired technicians, intelligent transformation of the breeding shed, ecological aquaculture eel is very popular in the market."

Under the ecological farming mode, local fish such as carp, grass carp and silver carp are stocked in the sedimentation tank of the eel base, which can not only purify the water quality but also increase the output value. At the same time, the silt that is regularly cleared from the breeding pond is also recycled to become fertilizer for the surrounding navel orange, oil tea, tea and other planting bases.

The base adds 30,000 yuan to the collective economy of Baishui Village every year and absorbs more than 10 villagers for employment. "I can work at my doorstep, make money and take care of my family." Baishui village villager Fu Pingxiang said.

The development of aquaculture with special characteristics has not only improved the supply of important agricultural products, but also promoted the income of fishermen. The per capita disposable income of fishermen in China reached 23,800 yuan last year.

Transform to modernization, and improve the scale, intelligence and standardization of aquaculture

In the aquaculture base of Haixing Aquaculture Co., Ltd. in Wuhan City, Hubei Province, a row of aquaculture workshops stands. Here is the largest industrial seafood land farming base in Hubei, put into operation at the beginning of the year, the first batch of prawn was just listed at the end of March.

Entering the workshop, the temperature display above the wall of the pool indicates that the water temperature is 28 degrees Celsius. "Shrimp love the temperature." Workshop technician Cao Guangfa carefully lifted the shrimp cage from the water, and a light bluish gray South American white shrimp jumped happily. Every four hours, he observes the status of the shrimp and sprinkls the prepared nutrition into the shrimp pond through an automated feeding system.

"Through scientific breeding, the shrimp raised are well-proportioned and the meat is sweet and sweet." Wu Yulin, head of the base, said it takes more than 70 days to grow from 2 mm small shrimp to palm-sized shrimp. In order to provide a suitable environment for shrimp seedlings, the base will desalinate the sea salt brine rich in microorganisms, so that each shrimp pond can maintain a suitable temperature of 28-30 degrees Celsius, and achieve continuous production in four seasons.

When it comes to production capacity, Wu Yulin breaks his finger to calculate: a 32-square-meter shrimp pond can produce more than 480 pounds of prawn, which is nearly 10 times the traditional farming model. There are 308 shrimp ponds in the base, and the annual output can reach nearly 900,000 jin according to the calculation of 6 crops per year.

How to achieve high-density intensive farming?

"It's all about technology." Wu Yulin said.

In the workshop, the intelligent monitoring and management system monitors water temperature, illumination, dissolved oxygen, pH value and other parameters for 24 hours. Out of the workshop, the water circulation system of shrimp breeding process independently developed by the base is running. Wu Yulin introduced, aquaculture sewage first through the large micro-filter, and then into the four-stage filtration system, purified water after heating back to the shrimp pond, "the treated water recycling, the utilization rate reached more than 99.5%."

Last year, the output of fishery aquaculture in China was about 55.68 million tons, accounting for 81% of the total output of aquatic products. While the total output of aquatic products has maintained a reasonable growth, China has coordinated the rational utilization of fishery resources and the protection of the fishery ecological environment, and put forward the development policy of "ecological priority, combining cultivation and fishery, and giving priority to cultivation" to promote the high-quality development of the industry.

"You can't get food from rivers, lakes and oceans without modern aquaculture." Yuan Xiaochu, deputy director of the Fisheries Administration Bureau of the Ministry of Agriculture and Rural Affairs, said that in recent years, various regions have continuously improved the scale, intelligence and standardization of aquaculture through the development of factory recirculating aquaculture and pond engineering recirculating aquaculture, and gradually improved the unit water output rate, resource utilization rate and labor productivity.

More modern facilities fisheries projects are being hatched. "The city vigorously carries out the construction of efficient facility fishery projects, and the annual financial subsidy exceeds 10 million yuan." Wang Wengao, deputy director of the Wuhan Municipal Bureau of Agriculture and Rural Affairs, introduced that the fishery demonstration base of efficient facilities such as pond channel aquaculture, "zero emission" captive green and efficient recycling aquaculture, container or factory recycling aquaculture, which meets the conditions and reaches a certain scale, will be awarded and compensated in accordance with no more than 50% of the total investment of the project, and the maximum amount can reach 2 million yuan.

Steady grain fishing, ecological aquaculture, green development of fisheries background bright

At the Li Shengyou grain planting family farm in Longji Town, Sihong County, Jiangsu Province, crayfish that have just been released swim among the water plants in the ring ditch in the rice field of more than 300 mu.

"Basically all Tangkou have released shrimp seedlings this year, and the first batch of shrimp will be put on the market in May or June, and the rest will continue to grow in the rice fields and be sold at different peaks around the National Day." Li Shengyou, head of the farm, said that by balancing the symbiotic relationship between aquatic grass, shrimp and rice, better economic benefits can be achieved. Last year, his shrimp paddy field averaged 1,100 pounds of rice and 200 pounds of crayfish per mu, which increased the benefit by more than 1,000 yuan compared with conventional rice planting.

Sihong County is located in the west of Hongze Lake, relying on the advantages of water resources, the county vigorously develop rice and shrimp co-cultivation, production of green rice, ecological lobster. In 2018, Longji Town was rated as a national rice-fishery comprehensive cultivation demonstration zone.

"Shrimp cultivation in rice fields, one water double harvest, but also reduce the amount of pesticides and fertilizers nearly 60 percent." Longji town senior agronomist Liu Chuang introduced that crayfish eat rice paddy grass, aquatic insects, rice stalks returned to the field after harvest, gradually decomposed after irrigation, so that plankton mass reproduction, promote the growth of water earthworms, and provide natural feed for crayfish. Last year, the town of rice shrimp a total area of 25,000 mu, to create the "Ying lake pearl" organic rice market.

Rice and fishery integrated farming is a typical ecological cycle agriculture model. "Adhering to the basic principles of stabilizing grain and promoting fishery, orderly development, green ecology and increasing people's income, the integrated cultivation of rice and fishery has shown good social, economic and ecological benefits." Yuan Xiaochu said that in 2021, the country's rice and fishery comprehensive cultivation area reached 39.6612 million mu, rice output was nearly 20 million tons, the output of aquatic products was 3.5569 million tons, and the income of farmers (fishermen) increased by more than 65 billion yuan.

Production methods are becoming more ecological, the ban on fishing and the withdrawal of fishing are progressing smoothly, and the background color of the green development of fisheries is becoming more and more distinct.

The 10-year ban on fishing in the Yangtze River is an important measure for the green development of the Yangtze River Economic Belt, which has entered its third year this year. Monitoring shows that the amount of fish species and resources in the Yangtze River basin has gradually increased, the range of activities of some species, especially the finless porpoise, has significantly expanded, and the aquatic biological resources have shown a good trend of recovery. At the same time, more than 200,000 retired fishermen have been successfully transferred to employment and have been fully guaranteed.

In Tuanfeng County, Hubei Province, fisherman Li Hansheng grew up on boats and spent most of his life fishing with his parents. After the Yangtze River fishing ban, Li Hansheng put down his fishing net and became a fish protector, "to see the fish that I have not seen for a long time come back, I am very happy."

Hu Jianxi, a villager in Xujialou village, Tuanfeng Town, was busy managing the lotus root belt he had just planted. With his knowledge of the habits of aquatic products, Hu Jianxi quickly found a way out. In 2021, he contracted 60 acres of ponds in the village and started four big fish and crayfish farming. After the first taste of sweetness, Hu Jianxi began to develop aquatic vegetable cultivation, and led the establishment of cooperatives.

Zhan Zhigang, chief of Tuanfeng County fisheries law enforcement brigade, introduced that in recent years, the county has established a dynamic management account for 103 fishermen in 52 households in the county to help retired fishermen find employment. We will expand employment channels through support for self-employment, placement of public welfare posts, training and recommendation, so that retired fishermen can find stable employment.

"The resettlement guarantee for fishermen who retire from fishing is the foundation and basis of the 10-year fishing ban in the Yangtze River." Ma Yi, director of the Yangtze River Basin Fisheries Administration Supervision and Management Office of the Ministry of Agriculture and Rural Affairs, said that this year will continue to increase policy support and work implementation efforts, through strengthening skills training, guide the development of rice and fishery comprehensive farming, aquaculture, recreational fisheries, etc., both long and short, and take multiple measures to stabilize the return of fishing fishermen to employment channels, improve the level of social security.
