As early as the 50s, when the commercial value of hairy crabs had not been tapped, the predecessor of Shui Xian, Bacheng Fishery Cooperative, had begun to explore artificial breeding. As the No. 001 franchise unit of the national Yangcheng Lake hairy crab geographical indication protection product, Shuixian was the first to pass the ISO14001 and ISO9001 certification system, meet the export standards, and successively won the honors of Jiangsu famous brand and Jiangsu famous trademark, and won the gold medal in many hairy crab promotion meetings, and became the designated crab of Beijing Diaoyutai Hotel.
 
The Aqua Fairy brand belongs to Kunshan Aquatic Products Co., Ltd., and its own water surface is located in the core production area of Yangcheng East Lake, which has been less affected by the action of returning crabs to the lake in recent years. As an old brand with a history of more than 60 years, Shui Xian has the whole process of breeding from baby crabs to adult crabs, and the crab seedlings are put into Yangcheng Lake at the stage of baby crabs, and they enter the wide natural breeding environment earlier, but they need to overwinter, and the requirements for breeding management are higher. Compared with many hairy crabs that only molt 7 or 8 times in February and March of the following year, the aquatic fairy hairy crabs have experienced a total of 19 molts in Yangcheng Lake, and their growth is slow and solid.
 
The return of crabs to the lake was part of two "three-year ecological optimization action plans" in Jiangsu Province between 2013 and 2018. Since 2002, the water quality of Yangcheng Lake has deteriorated due to fishing exhaustion, and the government has had to drastically reduce the area of hairy crab purse seine culture from 180,000 mu to only 16,000 mu in 2017. After returning the crabs to the lake, the water quality of Yangcheng Lake has improved, but it still maintains the state of class IV water quality with mild eutrophication, and there is no outstanding point. Promoting ecological aquaculture is the only way for the sustainable development of Yangcheng Lake.
 
From seedling selection, feeding to adulthood, the hairy crabs in the water are all completed in the original ecological environment, which not only reduces the water pressure of Yangcheng Lake, but also exercises the physique of hairy crabs. Hairy crabs mainly eat snails, small fish and other high-protein fresh bait, supplemented by corn kernels to supplement cellulose to help digestion, adult crabs are thick and fresh, cream yellow and full, rarely will be organic certification, national green products, national pollution-free products all won the title.
 
Aquaxian's courier partners, including China's cold chain giant SF Express and international giant FedEx, choose the most suitable 5°C low-temperature refrigeration for hairy crab hibernation, and provide next-day delivery and time-limited delivery services. It is rare in China that the water fairy can be supplied overseas, and the dead crab must be compensated within 6 hours after signing, which is a normal level in the industry.
 
As a representative of China's high-end hairy crab brand, Aqua Fairy provides a rare 6 pairs of gift boxes in the industry, male crabs weigh 3.2 two, female crabs 2.2 two, the lower limit specifications are higher than the general brand, so the price of 4 pairs of gift boxes also starts at 688 yuan, and 6 pairs can reach more than 3300 yuan.
