1. Due to the more and more serious environmental pollution, the natural amount of shrimp is getting less and less, and artificial breeding has become the mainstream production mode. The breeding method of Penaeus monodon is simple and adaptable. Riverside, pond and seaside can be raised. At present, there are basically three common breeding methods. Coupled with the maturity of culture technology, the current cultivation of new prawns with a knife amount generally has a fair profit.

2. As far as the current general trend is concerned, the price of new prawns is rising steadily. First, the price of the new prawns is becoming more and more popular, and more and more people can afford it, so the demand is rising. Second, due to the influence of previous years, a large number of farmers closed down, and the supply of new prawn market was insufficient. In addition, the new prawn with a knife is now a necessary food for many holidays, and some vendors hoard their products for the holidays. The daily supply is therefore reduced.

3. Taking an acre of land as an example, the cost from renting land to pruning to suitable breeding is about 20,000 yuan, and the later feed is also about 20,000 yuan, which adds up to about 40,000 yuan. The yield per mu is about 2,000 Jin, and the average selling price is 30 yuan/Jin. The net profit is about 2000*30-20000=20000 yuan. Excluding some losses and non-direct sales, the total profit is about 15000.
