So how much is the net profit per mu from crayfish farming?
I. How much is the net profit per mu from crayfish farming
1. First is the yield. If intensively farmed, the yield will be higher than extensive farming. But the corresponding cost will also be greater. It is directly proportional. With extensive farming, the annual yield per mu is about 500 jin to 600 jin.
2. The current market price is also set according to different seasons and different shrimp sizes. I calculate that adult large shrimp are sold in peak season. At 30 per jin. One mu can earn at most 18,000 yuan, and 2 crops can be farmed a year. The annual profit from farming crayfish on one mu is generally more than 10,000 yuan, but if they cannot be farmed successfully, there will be no such profit.
II. How to carry out shrimp pond conditions and cleaning
1. Shrimp pond conditions
It is transformed from low-lying land, with each pond covering 3 to 5 mu, a total area of 80 mu, a water depth of 1.1 to 1.5 m, a slope ratio of 1:3, loam soil, and a pollution-free water source. Each pond is equipped with a microporous aeration system with a power of 1.5 to 2.2 kilowatts; the water inlet uses a 60-mesh nylon sieve silk mesh bag to filter the incoming water to prevent wild fish and fish eggs from entering the pond, and the drainage outlet is installed with a fine-mesh net to prevent freshwater shrimp from escaping.
2. Pond cleaning
The pond silt must be cleaned out thoroughly. Half a month to one month before stocking, use quicklime for disinfection to improve the pond bottom substrate. Then also clean out the wild miscellaneous fish thoroughly to avoid competing for food.
3. Planting and transplanting aquatic plants
In the shallow water zone along the pond edge, plant aquatic plants such as hornwort, Elodea, and tape grass around the perimeter, with the aquatic plant coverage accounting for 20% to 30% of the shrimp pond area.
