Crab (páng xiè): Animalia, Arthropoda, Crustacea, Class Molluscs, Subclass Eumolucida, Order Decapoda, Suborder Gastropoda, Order Brachyura. It is a crustacean, with a hard shell protecting its body and breathing through gills. In biological taxonomy, it is the same animal as shrimp, lobster, and hermit crab.

Most species of crabs live in the sea or near the coast, and some live in fresh water or on land. They rely on female crabs to give birth to baby crabs, and each time the female crab will lay a lot of eggs, the number can reach millions or more. Crabs rely on the geomagnetic field to determine the direction. The number of genetic materials of this type of organisms is complex and has great differences, often up to more than 100 pairs. Common crabs include hairy crabs (river crabs, hairy crabs, clear water crabs), swimming crabs, etc. my country has abundant crab resources, among which the hairy crabs produced by Gucheng Lake hairy crabs, Taihu Lake hairy crabs, Gaoyou Lake hairy crabs, Yangcheng Lake hairy crabs, Xielou hairy crabs, Xinghua hairy crabs, and Hongze Lake hairy crabs in the lower reaches of the Yangtze River are top-quality hairy crabs.

How much money do you think you can make from raising crabs per acre? What should you pay attention to?

The cost of raising crabs per mu is about 480 yuan for crab seedlings, about 1,200 yuan for land rent, about 1,200 yuan for concentrated feed, about 900 yuan for water plants, snails, crab medicine, water and electricity fees, etc., totaling about 3,780 yuan. The market price of 600 crabs is about 10,800 yuan. After deducting the cost, the profit margin is about 7,020 yuan per mu. However, there are certain differences in prices across the country, so everyone should take the local price as the standard.

1. Cost and Profit

1. Investment costs

If you want to raise one acre of crabs, the total number of crab seedlings you need to invest is about 600, and the price of a crab seedling is about 0.8 yuan. For one acre of crabs, the cost of crab seedlings is about 480 yuan. The rent of one acre of land is about 1,200 yuan. During the breeding process, the cost of concentrated feed for one acre of crabs is about 1,200 yuan, and some aquatic plants and field snails need to be added. The price of this part is about 700 yuan. During the breeding process, crab medicine and water and electricity fees are also needed, and the cost of this part is about 200 yuan. The cumulative investment cost is 3,780 yuan.

2. Profit

When one acre of crabs is profitable, the price of a crab is likely to be around 18 yuan, so the price of N600 is about 10,800 yuan. After deducting the cost, the profit is about 7,020 yuan. When feeding, some small crabs may also be bred, and the profit of this part is negligible.

However, the price trends in each region may be different, so when making estimates, you should still use local prices as a guide and go to the local market for more consultation.

2. Crab breeding technology

1. Capital construction of ponds

First of all, we need to do a good job in pond construction, and choose a clean place for breeding. When breeding, it is best to transplant some aquatic plants in it, which will be more conducive to its growth and development, and can also ensure the water quality. Before putting the seedlings, sprinkle appropriate amount of quicklime powder in it for disinfection. This work is best done about 20 days in advance. Wait until its toxic side effects disappear before putting crab seedlings.

2. Zheng Qi Feeding

When breeding crabs, you must do a good job of feeding them. Feeding them three times a day is a better way. When feeding, you can choose some fresh ingredients such as fish and shrimp to feed them.

3. Management methods

Usually, you should do a good job of managing it, increase the frequency of inspection, and if you find something wrong with it, you should take timely measures to prevent it. Crabs are also likely to escape, so you should also prepare a plan to prevent them from escaping in order to avoid losses.

One acre of land should earn between 20,000 and 30,000 yuan. What needs to be noted is that when we raise crabs, we should not raise too many. There is a fixed number for each acre of land, and we should prepare food for the crabs every day. We must prepare some fresh food and ventilate them in time. We should also produce more oxygen.

You can earn about 10,000 yuan per mu of crab farming. The profit of crab farming is still very high. When breeding crabs, you should choose some good water quality, put some algae in the water, do a good job of escape prevention, and do a good job of shading. Don't let the crabs be directly exposed to the sun. Apply appropriate fertilizers like Changpeng crabs every day. They are very plump and will sell for a good price.

1. The size of crab seedlings for stocking refers to the size of the crab seedlings you need to buy. Generally, crab seedlings of 3-4 grams are stocked.

2. The number of crab seedlings to be released. Generally, 600 crab seedlings can be released into one acre of land. If you have 100 acres of land, you need to release 60,000 crab seedlings. If the price is 2.5 yuan per crab seedling, you will need to buy 150,000 yuan for crab seedlings alone.

3. Feeding for crab seedling breeding. A total of 3.2 tons of feed is needed in the breeding process of crab larvae, so the cost of feed is 20,000 yuan. In the early stage, the crab seedlings are relatively small and need a certain amount of feed. In the later stage, when the crabs grow to one kilogram, they can find food by themselves, so there is no need to feed too much feed.

4. The cost of renting a pond for crab breeding. Since you are going to a rural area for aquaculture and you are not a local, you will need to rent a pond to raise crabs. If it is an economically developed area, the pond rent will be 24,000 yuan a year. If it is a rural area with a poor economy, it will generally be around 5,000 yuan a year.
