Generally, the amount of shrimp per mu is 60-80 kg, and the mantissa per kg is 40-60, that is, the amount of shrimp per mu is between 2400-4800, and the lobster with the specification of 234 is selected. Generally, the shrimp fry are from 100 to 120 Jin per mu, and the mantissa of one Jin is about 100, which is about 1 yuan.

To sum up, in autumn, shrimps are planted with an area of 60-80 kg/mu, and 234 lobsters are selected. In spring, shrimps are released with an area of 100- 120 kg/mu, and the price of shrimps is about 1. This is the normal amount of shrimp and shrimp fry we usually put in. Breeding friends can make appropriate adjustments according to the actual situation of their ponds and their breeding density. Too high density is easy to breed related problems, and too low density can not guarantee the yield. However, for initial farmers, it is not recommended to raise the density too high.
