There are many hairy crab producing areas in China, and crabs are cultivated in lakes such as Jiangsu, Anhui and Hubei. However, due to the different waters and farming methods, there will be differences in appearance, taste and price The hairy crabs in Yangcheng Lake, Suzhou are the most famous and recognized in China. Of course, the price of crabs is also more expensive than other producing areas. ? All this is related to the special ecological environment of Yangcheng Lake, which lies between the Yangtze River and Taihu Lake. The water flow in this place is slow, so many nutrients will settle down. This hairy crab provides enough nutrition. The water level of Yangcheng Lake itself is relatively stable, with little change in different seasons. In this case, it is extremely beneficial to the habitat and survival of Yangcheng Lake hairy crabs. In this case, Yangcheng Lake has become a famous crab producing area.
Different from other lakes, the bottom of Yangcheng Lake is mostly hard, with more sediment on the surface, while the bottom of other lakes is basically silt. This provides an open activity place for hairy crabs. They often run around, climb up and down along the aquatic plants, exercise their muscles and make their meat naturally delicious. In Yangcheng Lake, the proportion of calcium, magnesium, silicon, aluminum and oxygen is rich and balanced, which makes crabs healthier and has a unique sweetness.
? The aquaculture waters are limited, and the annual output of authentic Yangcheng Lake hairy crabs is actually relatively fixed. However, the demand for hairy crabs in all parts of the country greatly exceeds the output of Yangcheng Lake, and the serious shortage of supply leads to the high price of hairy crabs. Moreover, before 2007, there were 32,000 mu of crabs in the purse seine of Yangcheng Lake hairy crabs. Later, the government began to clean up one after another and demolished 8,000 mu. The biggest change is that in 20 16 years, the government dismantled the purse seine culture 16000 mu at one time. Today, Yangcheng Lake hairy crab purse seine farming area is 8000 mu, which is three quarters less. So this has pushed up the price of Yangcheng Lake hairy crabs.
