Hello, this is a specialty of Zhongshan, Guangdong. I am from Shunde, Foshan next door. My dad loves this, so we often buy it. However, this fish depends on the season. It is usually only eaten during hot pot in winter. Introduce, the whole fish in our market sells for 15 yuan per catty, the price for surgery is 18 yuan, and the hot pot in restaurants is about 25-30 yuan. Due to the high price, farmers raise the fish to about 3.5-5 catties. They are sold only by size, and the ones here are fatter, usually 6-7 pounds, so we usually buy half of the surgical ones, which is about more than 50 yuan.
