At 1 a.m., at the aquaculture base in Hetao Street, Chengyang District, Qingdao, a loud horn pierced the night sky.
"One, two, three, it's up!" Wang Shujian waited hard for three months and finally ushered in the closing time.
Under the illumination of the searchlight, tens of thousands of bamboo shrimps "dance" on the Internet, and the blue-brown patterns on the whole body are clearly discernible.
"Look, those who are alive and kicking, be sure to leave a basket for me!" Some surrounding citizens have been waiting for 3 hours, just to grab the "first fresh".
Prawns and beer are the "top stream" in Qingdao night market and on the table.
In the past, the production of prawns in Qingdao was low and the price was high, and it was almost impossible to eat in other places.
In recent years, with the jump in nursery and aquaculture technology, Qingdao shrimp has achieved high yields and the price has become more affordable.
Fresh Qingdao prawns will land on Pinduoduo's 4th Farmers' Day, which will last for 24 days from August 21.
It is reported that Pinduoduo has launched the "Super Farmer's Festival" with an "online duration" of 24 days. It spans the two important solar terms of "Qiu Shi" of Lushu and Bailu, covering 200,000 types of agricultural products and more than 100,000 agricultural-related stores nationwide. Family.
From now on, from north to south, from Liaoning Panjin rice, Shandong Qingdao prawn, to Guangxi snail powder, Yunnan Menghai Pu'er tea, Binchuan soft seed pomegranate; from west to east, from Sichuan Xichang sunshine rose, Shaanxi Dali winter jujube, Zhouzhi Kiwifruit, hairy crabs in the Yangtze River Delta, Fujian Pinghe honey pomelo... Many high-quality agricultural products of origin will usher in their home sales on Pinduoduo one after another.
Relying on the channel advantages of e-commerce platforms such as Pinduoduo and the support of the cold chain logistics system, Qingdao prawns in the north can be delivered to inland villages within 48 hours.
Qingdao aquatic products represented by prawns are "touring" out of Qingdao and "touring" to the whole country.
Ships from Qingdao and can be delivered to consumers in Wuxing Village, Zhuozi County, Inner Mongolia within 48 hours.
Frontline Visit: Cod Seafood as Bait
In August, the whole province of Shandong welcomed a high temperature.
At 8 o'clock in the morning, the temperature in the Hetao area of Qingdao had reached 33 ℃.
Wang Shujian rowed a rickety boat and got busy in the pond.
"The waters here in Qingdao have high salinity, and shrimp grow slowly. They are characterized by their large size, firm meat, and delicious taste." As a farmer with more than 10 years of experience in aquaculture, Wang Shujian believes that The reason why the quality of Qingdao shrimp is outstanding, "mainly is the environment is good, the seedlings are good, the food is good, and one more point, it is determined not to use drugs." In order to enhance the physique of the shrimp, before a new batch of shrimp seedlings are released, it is necessary to supplement the water body. C, calcium and other nutrients.
At 3 o'clock in the afternoon, the sun was fierce, and Wang Shujian went down to the pond again to feed the young shrimp.
The bait for bamboo shrimp is generally "sea sand", clams and other small shellfish seafood.
After the Penaeus vannamei entered a period of rapid growth, they were fed with cod meat.
"Qingdao shrimp grew up eating seafood, and they eat better than humans!" Wang Shujian said.
Qingdao prawns mainly involve three species: Chinese native prawns, vannamei prawns and Japanese bamboo prawns.
The more than 1,000 acres of shrimp ponds contracted by Wang Shujian are all bamboo shrimps, which are harvested twice a year and ushered in two harvest periods in August and October.
Gou Kaidi, a 40-year-old native of Qingdao, has been raising South American shrimp for eight years. From the end of June to the end of August every year, he is most anxious.
At this stage, it is easy to get sick, and the infection rate is extremely fast, and even three days will be clear and the pond will be completely harvested.
"Shrimp sleeps during the day and moves at night, so every day from 8 o'clock in the evening to 4 o'clock in the morning, each of our shrimp ponds has to be vigilant and keep an eye on them." Shrimp farmers must observe the swimming of shrimp at night. Situation, "If you swim slowly, have no energy, and don't jump, it's dangerous!"
In order to get the most delicious time for Qingdao prawns, shrimp farmers have to work hard for 90 days and nights from seeding to collecting nets.
"Only the moment when the net is closed, can the heart be put down." Gou Kaidi said.
Technical challenges: local seedling scientific research overweight greenhouse farming is becoming more and more mature
In the past, Qingdao's prawn industry was dominated by native Chinese prawns, which had high disease rates, low yields and high prices.
In recent years, with the increase in scientific research on seedlings, the maturity of factory farming in greenhouses, the continuous improvement of the cold chain logistics system, and the increasing availability of Internet e-commerce channels, Qingdao prawns have truly gained the confidence to "sell the whole country". .
Seedlings are the "chips" of aquaculture, which once became a "stuck neck" problem that plagued the development of Qingdao's prawn industry.
Taking Penaeus vannamei as an example, its provenance is almost always monopolized by foreign countries.
In recent years, relying on a number of sea-related colleges and universities such as Ocean University of China and the Yellow Sea Fisheries Research Institute, Qingdao has continuously increased its scientific research strength and made breakthroughs in domestic seedlings.
In 2017, the Shrimp Germplasm Resources and Breeding Innovation Team of the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences participated in the construction of the Penaeus vannamei Genetics and Breeding Center in Shandong. The improved varieties of white shrimp have driven the high-quality development of the national shrimp industry through radiation.
"Raising shrimp is a hard job and a technical job." Wang Shujian concluded: the qualification of seedlings, the density of placement, temperature management, disease control, etc. all affect the yield.
The yield per mu of some farmers can be as high as 1,000 jin. Once the management is not in place, it is also possible that the production of the pond will cease to be produced, and the grains will not be harvested.
Wang Shujian introduced: A straight body and a raised tail are good shrimps.
In recent years, farmers in Qingdao have begun to introduce greenhouse aquaculture technology. Through the control of environmental factors such as greenhouse temperature and water salinity, the growth cycle of Penaeus vannamei has been increased from 1 crop a year to 3 crop a year. The time to market is about 3 months in advance.
Farmer Xu Zhaoqiang said that the per-mu yield of bamboo shrimp in ponds is about 100 kg, while the per-mu yield of Penaeus vannamei is relatively lower; while the density of greenhouse-cultured Penaeus vannamei is high, with an average yield of about 1,000 catties per mu.
The prawn industry in Qingdao has undergone a large-scale transformation from marine aquaculture to pond aquaculture, greenhouse aquaculture, and factory aquaculture.
At present, many farmers are undergoing factory transformation. The factory breeding workshop provides sufficient oxygen and feed, and the output of shrimp is further increased.
Industrial upgrading: 10,000 orders per day, Qingdao prawns "tour" the country for 48 hours
In August, Chen Xin, a consumer who lives in Yaojiabu Natural Village, Zhuozi County, Ulanqab City, Inner Mongolia, placed an order for Qingdao prawns on Pinduoduo. The next day, white shrimp from Qingdao "climbed" onto the dining table.
"It's as big as 14 or 15 centimeters, and the price is not expensive. After the platform subsidizes more than 20 yuan a pound, it can still be cold-chained to home." Today, consumers as far inland as Chen Xin can move their fingers. Eat high cost-effective Qingdao seafood.
If it is said that the Qingdao aquaculture industry guards the quality of Qingdao prawns with "original intention", then there are still a group of young people who are competing for e-commerce and are building "fast boats" for the Qingdao prawn brand to "go overseas".
Cui Chenglong, from Yantai, Shandong, born in 1995.
After finishing university in Qingdao, Xiao Cui has worked in real estate and car sales successively, and finally aimed at the field of agricultural products e-commerce.
In 2019, Xiao Cui led the operation team to settle in Pinduoduo, specializing in Qingdao aquatic products, with prawns as the flagship product.
"Although we entered the game relatively late, it is very important to choose the right platform. Pinduoduo started out in agriculture and has support for agricultural product merchants. In addition, we have the advantage of Qingdao seafood supply chain. I don't think it will be bad."
Xiao Cui's team is also making adequate preparations for participating in Pinduoduo's Farmers' Festival.
In the delivery factory, Cui Chenglong displayed the packaging materials innovatively designed by the team for Qingdao prawns: the encrypted and thickened foam box is inlaid with card slots, and the frozen shrimp are placed in the card slots to avoid bumps and facilitate heat insulation.
There are ice packs and dry ice next to the card slot.
"We borrowed the packaging material of ice cream and used it in the transportation of aquatic products, including during this year's Super Farmer's Day, most parts of the country can be delivered in a 48-hour cold chain." Xiao Cui said.
It is reported that since August 2019, Pinduoduo has held the Agricultural Commodities Festival for four consecutive years, and the radiation production areas have expanded from 500 in 2019 and more than 1,100 in 2021 to nearly 2,000 today.
In this Agricultural Commodities Festival, in addition to investing tens of billions in subsidies on the basis of "zero commission" for agricultural products, the platform will also cooperate with nearly ten counties (cities) in Hubei and other places to carry out live broadcasts to help farmers. , to drive the sales of advantageous agricultural production areas, and enhance the reputation and influence of branded agricultural products and landmark agricultural products.
Xiao Cui's team is also making adequate preparations for participating in Pinduoduo's "Super Farmer's Festival".
In order to break people's stereotype that Qingdao prawns are "too expensive", Xiao Cui's team focuses on the marketing and promotion strategy of "freshness, origin, quality, and cost-effectiveness", and quickly created several popular products. Profit was achieved.
At present, its annual sales of Qingdao prawns in Pinduoduo reach 42 million yuan, with a monthly shipment of 380,000 orders, and a peak season of up to 10,000 orders per day.
In the peak season every year, it can also provide nearly 500 flexible employment positions for the surrounding villagers.
"Good agricultural products such as Qingdao prawns must not only be produced, but also sold. We started with farmers and innovated 'farmland cloud fight' to promote large-scale 'production and marketing connection' of high-quality agricultural products, which has always been the work of the platform. The key point is that the annual Farmer’s Day is one of the most effective starting points.” The person in charge of Pinduoduo’s Farmer’s Festival said that this year, a total of 1.5 billion support resources will be invested in the Farmer’s Festival to share the joy of autumn harvest with farmers, consumers and businesses. , hoping to help high-quality aquatic products such as Qingdao prawns swim into thousands of households, and also bring more employment and income opportunities to the local area.
