Heze Newspaper reporter Jiang Peijun Guo Weidong.
In recent years, Heze has continued to strengthen the ecological protection of the Yellow River Basin and promote the high-quality economic and social development of the city. The wetland of the Yellow River Ancient Road is rich in biodiversity and has unique natural landscapes. Among them, the network of Taihang Dike and Sanku River in Weiwan Town, Cao County is criss-crossed, lotus root rice fields are dotted, and the superior wetland environment is particularly suitable for the growth of aquatic animals such as fish, shrimp and crabs. Since October, the crabs here have been "landing" and crawling to the tables of thousands of households. The reporter of Heze Newspaper recently walked into the third reservoir of Taihang Dike in Weiwan Town, Cao County, and "crab" with the majority of aquaculture farmers.
960 acres of crabs climbed onto the table.
Collect the net!On December 9, in the aquaculture area of Taihang Dike Sanku, Weiwan Town, Cao County, with a shout, farmers rolled up their sleeves and went into the water to collect the nets.
The crabs in the nets wield their sturdy claws, and the farmers neatly plucked them from the nets and carefully tossed them into the buckets. Watching the big crabs "come ashore" alive, the faces of the farmers showed the joy of a bumper harvest.
Fishing boats go to cast nets in winter, and crabs are full when they return from fishing. The boiling water of the Yellow River has given the people of Taihang Dike Sanku, Weiwan Town, Cao County, the most precious natural gift.
In 2015, 50-year-old Wang Fuhua contracted land in the third reservoir of Taihang Dike in Weiwan Town, Cao County, dug ponds, and established the Cao County Yunhe Aquaculture Professional Cooperative to breed river crabs, vannamei shrimp and four major freshwater fish.
The aquaculture area we currently see is about 960 acres, in which the river crabs are planted in the spring, harvested in the autumn, and begin to mature in October, and it is currently the best season for crab fishing. Wang Fuhua said. Unbasketing, unpacking, bundling, packing, shipping, this has been happening every day since October.
The crabs we caught today are big and thin, with an average of 3 per catty, and the price out of the pond is about 55 yuan per catty. Wang Fuhua introduced that in addition to the local market, these crabs will be sold to Shanghai, Tianjin, Jinan and other large and medium-sized cities.
Our products are very popular, and we have accumulated a lot of regular customers over the years. Li Wanhu, Wang Fuhua's partner, said proudly, "Our crab seedlings come from Yangcheng Lake in Jiangsu Province, which are delicious and very popular in the market. ”
Next to Wang Fuhua's pond, there is a clear river. She told the Heze Newspaper reporter that the water of this river comes from the Yellow River, and it is also the main water source of the Taihang Dike Sanku Aquaculture Area in Weiwan Town, Cao County.
Shrimp fat crab beauty has high income.
About 5 kilometers south of the ** station of Weiwan Town, Cao County, there is a wetland with dense rivers and ponds, which is the three reservoirs of Taihang Dike in Weiwan Town, Cao County, and the Yellow River Ancient Road National Wetland Park in Cao County is located here. The river network in the Sanku reservoir area of Taihang Dike in Cao County is crisscrossed, and the lotus root rice fields are dotted around, and the superior wetland environment is especially suitable for the growth of aquatic animals such as fish, shrimp and crabs.
Li Wanhu is from Suqian City, Jiangsu Province, graduated from an aquatic school in Nanjing, Jiangsu Province in the 80s of the 20th century, and after graduation, he was engaged in aquaculture as a technician in Lianyungang City, Jiangsu Province, and later engaged in aquatic production in Heze.
In 2011, I came to the third reservoir of Taihang Dike in Weiwan Town, Cao County, and found that the water quality and soil quality here are very suitable for aquaculture, so I started freshwater aquaculture. Li Wanhu recalled. As a technician with a "professional background", he has extensive experience in freshwater aquaculture of marine crab seedlings.
The three reservoirs of Taihang Embankment are rich in biodiversity and unique natural landscape, and the development of ecological aquaculture of river crabs is an important starting point for increasing fishery efficiency, increasing fishermen's income and enriching fishing areas. At present, Cao County in the reservoir area mainly promote shrimp and crab pond polyculture, lotus root (rice) crab comprehensive planting and breeding two modes, the use of grass planting, snail casting, sparse release, breeding, fungus, algae cultivation, water transfer, bottom modification eight technologies, through the creation of a benign pond habitat, so that the material cycle and energy flow more reasonable, so as to obtain the highest economic benefits.
In recent years, under the guidance of Cao County Aquatic Products Service Center, Cao County Yunhe Aquaculture Professional Cooperative has carried out shrimp and crab polyculture experiments. Penaeus vannamei and river crab both like to be lean in the water, shrimp inhabit the middle layer, river crab inhabits the bottom layer, river crab likes to eat artificial feed and other large particle size coarse materials, while shrimp prefer to feed plankton, bait and other small particle size fine materials, shrimp play a role in controlling feed and water transfer, and river crabs cannibalize weak shrimp, reduce the spread of shrimp white spot disease and other diseases, and indirectly reduce the incidence of shrimp.
After the seedlings are released every spring, Wang Fuhua and Li Wanhu not only pay close attention to the water temperature and water quality every day, but also pay great attention to the preparation of feed. "Our feed is uniquely formulated to be very suitable for aquatic animals such as fish, shrimp and crabs, so the crab meat is very full. Li Wanhu said.
Talking about the current production and income of shrimp and crabs, Wang Fuhua said: "The average yield of river crabs per mu is 70 kilograms, the average yield of vannamei shrimp is 125 kilograms, the average weight of female crabs is 130 grams, the average weight of male crabs is 170 grams, and the average weight of shrimp is 20 grams per tail, and the comprehensive profit per mu is about 5,000 yuan." ”
During the interview, the reporter of Heze Newspaper found that there are many kinds of waterfowl gathered in the aquaculture area of Taihang Dike Sanku, Weiwan Town, Cao County, like a "bird's paradise". It is understood that the waterfowl here include rare birds such as the Great Egret, the Little Egret, the Pond Heron, the Night Heron, the Gray Heron, the Cowback Heron, the Crested Fish Dog, the Yellow Reed Owl, and the White Bone Top.
So, are these birds harmful to fish, shrimp, crabs?"These birds are almost not harmful to our aquaculture because most of the fish and shrimp they prey on are sick and floating. These birds give us a signal that as soon as they fly to our aquaculture area, I know that there is something wrong with the health of the fish, shrimp and crab and that it is time to take immediate action. Wang Fuhua said.
Draw a new picture of increasing income and getting rich.
Purple crab cooked with frost, boiled wine and roasted red leaves.
After years of ecological breeding, Weiwan crabs and shrimp have been widely recognized by the market and consumers. "If you come in June or July next year, our vannamei shrimp will be on the market at that time, and the shrimp will be alive and vibrant, which is very gratifying. Wang Fuhua said proudly.
A crab enriches the biodiversity of the Yellow River, leads farmers in the reservoir area to increase their income and become rich, and at the same time drives the vigorous development of industrial chains such as warehousing and logistics, e-commerce, and rural tourism, drawing a new picture of continuous income increase and prosperity for local villagers.
The five flowers are tied, the belly is facing up, the ginger slices are pressed **, and the shell is thin and the red fragrance is unforgettable. In just a few sentences, it vividly describes the scene of people cooking crabs. For many people, the plump crab roe, tender crab meat, and fragrant crab paste can be described as a feast for the taste senses. However, you can't be in a hurry to eat crabs, and you need to use special tools to take your time. According to the record of "Examination and Eating", there were eight kinds of crab-eating tools in the early Ming Dynasty: hammer, upsetting, tongs, shovel, spoon, fork, scraper, and needle, so it is called "eight crabs".
Since ancient times, eating crabs has been a beautiful thing. In ancient Chinese literature, there are many records and poems about crabs.
The Tang Dynasty poets Tortoise Meng and Pi Rixiu were good friends, known as "Pi Lu", and were praised by Lu Xun as "the brilliance and edge in the muddy pond" at the end of the Tang Dynasty. Pi Rixiu gave Tortoise Meng a few crabs, and Tortoise Meng wrote a poem "Reward for Attacking the Beauty and Seeing the Sea Crab" to express his gratitude, two of which are "The bones are clear like spring mist, and the foam is white and suspected of having sea frost". It means that the crab bones are strange, and they seem to have spring dew in their mouths, and the white foam they spit out seems to carry the frost of the seawater, revealing their love for crabs between the lines.
Coincidentally, Xu Nidao of the Song Dynasty was also very fond of crabs. He wrote in "Crabs in Lushan": "If you don't go to Lushan, you will live up to your eyes, and if you don't eat crabs, you will live up to your stomach." Holding the chela wine and the mountain, there is no such joy in the world for three hundred years. ”
The crab walks "rampantly", from which some allusions are derived.
It is rumored that when Zhang Zhidong was the governor of Liangjiang, he went to the birthday banquet of the prefect of Songjiang one day. The prefect of Matsue didn't know him, so he was very cold. After the banquet began, Zhang Zhidong sat in the chief position. The prefect of Songjiang suppressed his anger, walked to Zhang Zhidong, pointed to a famous dish on the table, and came out with a couplet: "The four gills of the sea bass monopolize the Songjiang mansion." "The prefect of Songjiang compares himself with "perch", which means that Songjiang is my territory, and what qualifications do you have to monopolize the chief. Zhang Zhidong unhurriedly pointed to the crab and said the next couplet: "The crab is eight-legged, rampant in Kyushu all over the world." The prefect of Songjiang heard that the person who came was extraordinary, and after learning that it was Zhang Zhidong, he was even more shocked and hurriedly apologized.
For thousands of years, crab has not only been a delicacy, but also a cultural heritage. It is believed that with the development of society, crabs will continue to write classics, and at the same time bring people a good taste, they will add more luster to the aquatic industry.
