How many lobsters can be produced in an acre of land, how many lobsters can be raised in an acre of land, how many crayfish can be raised in an acre of pond, and how much money can be earned by raising lobsters in an acre of land? Generally speaking, an acre of land can produce 500-600 Jin of crayfish. If intensive cultivation, the output will be higher, but the corresponding investment will be larger. If it is lower than this number, it means that your shrimp seedlings are not enough. The density of shrimp fry is related to the size and water depth of shrimp fry. Please refer to the following methods for details.

How many catties of shrimp can you raise on an acre of land at most? How many shrimps should be put in an acre of land?

Seedling density depends on fry specifications, shrimp pond area, pond water depth, pond bottom conditions, water change conditions, bait types, feeding methods, production skills and management level, and should also be determined with reference to the yield requirements and specifications put forward by shrimp farmers. The number of released seedlings can be calculated with reference to the following formula:

Sowing amount = (planned seedling yield (kg) × required mantissa 1 kg)/estimated survival rate

Among them: the planned yield per mu can refer to the output of neighboring areas over the years; 1 kg shrimp can be counted as 30 ~ 50 (body length12 ~15 cm); The survival rate is calculated by 50% ~ 70%, and the middle shrimp is calculated by 85%.

In general, under the conditions of good shrimp seedling quality, superior water exchange conditions, guaranteed bait and high feeding management level, the amount of seedlings released per mu can be about 20,000 (no more than 25,000). The number of shrimp seedlings (about 2.5 cm long) cultivated in the middle is controlled between 8000 ~ 12000 per mu.
