The cost of growing shrimp is 58 yuan / jin, totaling 6960 yuan; site rent: 700 yuan / mu / year; feed, water and electricity charges: 2000 yuan; labor cost: 12000 yuan / year / mu; total-21660 yuan.

Breeding cost

The cost of growing shrimp is 58 yuan per jin, totaling 6960 yuan.

Venue rent: 700 yuan / mu / year

Feed, water and electricity charges: 2000 yuan

Labor cost: 12000 yuan / year / mu

Total-21660 yuan

Now suppose 120 jin of shrimp per mu, 20 per jin, then 120 jin is 2400, the ratio of male and female shrimp is 1:1, due to transport loss, it is assumed that the survival rate is 95%, that is, 2280.

The number of young shrimps produced by female shrimps is 1140 / 2 times / mu / mu / time = 45.6ind / mu / year, and the survival rate from spawning to growth of young shrimps is 8%. The total number of adult shrimps per year is 456000 / year × 8% / mu / year.

When the weight of each adult shrimp grows to 50 grams (about 10 / jin), the annual yield per mu is 6480 / mu / year / 12 / jin = 3040 jin / mu / year. Now assume that the market price of crayfish per jin is 10 yuan, excluding costs, one mu can earn 30400 yuan, 20 mu lobster can earn 608000 yuan, this is still a conservative estimate, the actual situation may be more than.
