The cost of raising an acre of crabs is about 480 yuan, the land lease is about 1.200 yuan, the concentrated feed is about 1.200 yuan, and the water plants, snails, crab medicine and utilities are about 3,780 yuan. The market price of 600 crabs is about 10800 yuan. Excluding the cost, the profit rate per mu is about 7020 yuan. However, there will be some differences in prices across the country, and everyone will take the local as the standard.

I. Cost and profit

1, input cost

If one acre of crabs is bred, the total number of crab seedlings to be put in is similar to 600, and the price of one crab seedling is similar to that of 0.8 yuan, then the cost of one acre of crabs to be put in is similar to that of 480 yuan. The rental price of an acre of land is about 1200 yuan. In the whole breeding process, the cost of concentrated feed for an acre of crabs is similar to that of 1.200 yuan, and some aquatic plants and snails need to be popularized, and the price of this part is similar to that of 700 yuan. In the whole breeding process, crab medicine and water and electricity costs are also needed, which are similar to those in 200 yuan. The accumulated cost of the project investment is 3780 yuan.

2. Profit

When one acre of crabs is profitable, the price of a crab leaving the pond is likely to be around 18 yuan, so the market price of 600 crabs is similar to 10800 yuan, and its profit is similar to 7020 yuan except the cost. In the case of breeding, it is also very likely that some small crabs will be bred, and this part of the profits will be ignored.

However, there may be some differences in quotations from each region. Therefore, in the case of forecasting, either the local price shall prevail and go to the local sales market to learn more about the situation.

Second, crab culture technology

1, reservoir capital construction

The first thing to do is to do a good job in the basic construction of ponds and choose clean areas for breeding. In the case of aquaculture, it is best to transplant some aquatic plants in it, which will be more conducive to its growth and development and ensure the water body. Before sowing, sprinkle appropriate amount of lime powder for disinfection and sterilization. It is best to carry out this work about 20 days in advance. Until its toxic and side effects disappear, put the crab seedlings again.

Step 2 feed

In the case of raising crabs, we must do a good job in raising them. It is a better way to feed crabs three times a day. In the case of feeding, you can choose some fresh ingredients such as fish and shrimp to feed.

3. Management methods

At ordinary times, we should do a good job in its management and increase the scope of inspection. If problems are found, they should be prevented in time. Crabs may also escape, so the countermeasures for ordinary people to escape need to be done well to prevent themselves from suffering losses.
