Selling a lot of prawns, what is the purchase price?

Because my friend doesn't have the area where you sell shrimp, and the prices in each place are different, we can only provide the prices in some areas, for your reference:

Guangdong Jiangmen 1: 18- 19 yuan/kg; (soup head price)

2. Changde City, Hunan Province: 25-26 yuan/kg; (soup head price)

3. Hangzhou, Zhejiang: 20 yuan/kg; (soup head price)

4. All parts of Hainan Province 15- 17 yuan/kg; (soup head price)

5. Changsha City, Hunan Province, 20-23 yuan/kg; (re-export wholesale)

6. Chengdu, Sichuan 28-30 yuan/kg; (re-export wholesale)

7.30 yuan/kg, Yichang City, Hubei Province; (re-export wholesale)

8. Wuhan City, Hubei Province, 22-25 yuan/kg; (soup head price)

The price of prawns changes every day, and the general rules are as follows: 1, the local meteorological conditions are poor, fishing and transportation are inconvenient, and the price is high; 2. The price is low from Monday to Friday, high on Saturday and Sunday, and high on holidays. 3. The farther north, west and northwest, the price will increase by 5 to 10 yuan.

In addition, in 2065.438+02-2065.438+03, the total output of prawns in China will be maintained at about 6,543,800 tons. Before 20 13, China can export about 200,000 tons every year, and it is a shrimp exporter. After 20 13, due to the influence of natural weather, the continuous deterioration of water quality, and the inability to eradicate infectious diseases, the price of marine prawns mainly produced in coastal aquaculture areas in China has risen sharply. China has also changed from an exporter to an importer, importing 200,000-300,000 tons of prawns every year. 20 12 year 40 prawns/kg price is around 12- 16 yuan/kg. Now the price difference is too big, and there is a lot of profit space. However, the overall quality is not good, because there are too many drugs in the main producing areas of seawater shrimp, and the drug residues are more serious.
