Crabs have always been popular with people, so what about the profits of crab farming?

River crabs in our country. In the early 90s of the 20th century, the industry developed rapidly with an average annual growth rate of about 30,000 tons, reaching 10,000 tons in 2006, and has become a world-renowned and unique aquatic industry in China. It has gone through three landmark stages of development:

From coastal to inland, from natural fishing to artificial ecological farming, from extensive aquaculture to the Seine.

Intensive. We can proudly say that China's river crab industry is world-class in terms of industrial scale, basic theoretical research and practical breeding technology promotion.

With the improvement of China's economic level, people's dietary structure has also undergone great changes, hairy crabs have entered the dining table of ordinary people's families, and consumers have higher requirements for the appearance and taste of hairy crabs, so the choice of hairy crabs is becoming more and more strict. It is said that high-quality crabs such as red paste crabs are not a few in the market, and crabs rich in selenium and clear water have been favored by consumers, and raising crabs is the first direction of the future, so it is distinctive.

Chinese"Internet+"strategy, a new orientation for information technology and a new orientation for traditional industries"Ecological integration", the Internet has gradually penetrated into the aquatic industry, Yangcheng Lake hairy crabs.

Enter **, Jingdong, No. 1 store.

and other e-commerce platforms have been operating very maturely. In the future, sales channels.

The increase in e-commerce platforms, the development of the Internet of Things, the traceability of aquatic products, and cold chain logistics.

The development of transportation and the breakthrough of transportation mode will bring great changes to the aquatic industry. The application of Internet + will inevitably become a trend that changes the aquatic industry, and the market prospect of hairy crabs will be better.

The crab market has been relatively stable and profitable, making it unique in the aquatic industry. Rice fields in the north, Seine crabs, and the Yangtze River basin.

Various models of ponds have a long history of breeding, with the instability of the common variety of aquatic products market and the decline of profits, the duck industry has a tendency to spread to the whole country, it is understood that Yunnan-Guichuan.

The river crab breeding industry in other provinces has gradually emerged, and the area of paddy fields in the country has shown a trend of increasing year by year. The Seine River pond crab with large specifications is 10-20 yuan higher, which shows that the quality of river crabs has entered the soft power.

At the level of competition, it is not only necessary to raise large, but also to raise excellence.

Crab is a very delicious seafood, and the profit of breeding crab is also very large, but you must learn scientific breeding methods, so as to be able to make money.

I think that the profit of crab farming is very high, and basically there can be more income than 3 or 4 times the cost.

The profit of breeding crabs is still quite high, and you can make a lot of money every year.

Even in coastal areas, this growth rate.

It's also pretty good. Wang, a professor at Xiamen University and executive director of the Crustacean Branch of the Chinese Zoological Society, grabbed a blue crab.

Look closely. The project acceptance panel, composed of well-known experts in the industry, unanimously agreed: "Saline-alkali land.

The technology of raising blue crabs has been explored in place, and the next step can be to try to widely promote it in saline-alkali land. "As we all know, there is no difference in taste and quality between blue crabs farmed in saline land and blue crabs farmed along the coast. Behind these achievements, the team has worked hard to overcome scientific research problems time and time again.

For example, the salinity of blue crabs farmed in coastal areas is mainly between 10 and 25, while the salinity of our breeding in the saline-alkali land of the Yellow River beach is that it will cause discomfort and death of blue crabs. Finally, the team continued to try to dilute the high-quality crab seedlings suitable for saline-alkali land culture through seedling desalination technology. Professor Wang Chunlin, dean of the School of Oceanography and team leader of Ningbo University, said that since then, the team has also explored reasonable polyculture techniques, and selected blue crabs, white shrimps, and tilapia according to different ecological habits.

Polyculture effectively ensures the stability of aquaculture production and the high income of farmers.

Catalyzed by blue crabs, fish and shrimp can be caught in batches earlier. This saline-alkali land used to grow corn and peanuts, and the crops of one acre of land were sold for 1,000 yuan. After the implementation of polyculture, the net profit per mu of land.

It can reach at least 13,000 yuan. The success of blue crab farming in saline-alkali land can be said to kill two birds with one stone. Yanjin County.

Most of the farmland is saline-alkali land, which is difficult to manage. Through this technology, the saline-alkali land will have great utilization value and become a "rich land" for the villagers. However, blue crab farming is mainly distributed in the southeast coast, with an annual breeding capacity of only 160,000 tons, which cannot meet the strong market demand.

Nowadays, the cultivation of saline land brings the possibility of abundant market supply.

The breakthrough of "Haimi" large-scale production technology can effectively save fresh water resources, increase the area of cultivated land, and contribute to environmental protection and sustainable agricultural development.

It is of great strategic significance to solve the problem of food security in China and even in the world. Integrated rice farming is a new ecological composite model of rice planting, aquatic product breeding and waterfowl breeding, which avoids the waste of space and resources caused by a single type of cultivation. The development of integrated planting and breeding of paddy fields can obtain considerable economic and social benefits, and can also bring good ecological benefits.

The integrated cultivation technology of freshwater paddy field is becoming more and more mature, but the integrated cultivation technology of seawater paddy field is rarely reported.

The national aquaculture area is more than 360,000 mu, and the output is more than 160,000 tons. In addition, the sales of high-end blue crab products have continued, and the "red paste crab" has exceeded 500 yuan kg (net weight after taking off the rope). Therefore, exploring the "blue crab sea rice" model may be one of the effective ways to increase farmers' income.

This study is based on Taishan City, Guangdong Province in 2019.

The production data of blue crab farmers in Duhu Town systematically analyzed the "blue crab-sea rice.

The technology and benefits of the co-cultivation model and the traditional blue crab-shrimp co-cultivation model were preliminarily explored, in order to provide a theoretical basis for the promotion and improvement of the "blue crab-sea rice" co-cultivation model.

Generally speaking, the profit of an acre is about 7,000 yuan, an acre of crabs, the cost of crab seedlings needs to be invested in about 480 yuan, there are about 600, a crab seedling is about 18 yuan, and the profit sold is about 10,800 yuan, in addition to the cost, the profit is almost 7,020 yuan.

Generally, the profit of one acre of land can be more than 50,000 yuan, it depends on the level of your blue crabs, if the blue crabs are relatively large, your profits will be very high.

I think it's hard to say the profit, because the level and method of breeding blue crabs are different for everyone, but the profit can generally be controlled at more than 20%, and some people may be higher.

About four or five thousand, the nutritional value of blue crabs is very high, and in the market, there are also high returns, which is very worthy of breeding.

It's probably more than 100,000 yuan, because one acre of land can breed a lot of blue crabs, and the ** of blue crabs is also relatively expensive.

The profit is about 10,000 yuan, because the cost of raising crabs is not particularly high, so the profit is very good.

The profit is not particularly large, only about tens of thousands of yuan, so it is still necessary to invest cautiously.

The profit is generally more than 50%, which can be regarded as a windfall profit, but only if your scale is large enough.

The profit of breeding blue crabs per mu is more than 10,000 yuan, and the profit is very considerable.

Overview of the benefits of crab farming:

The overall situation of crab breeding is good, with an average yield of more than 190 catties per mu, two female crabs and more than two male crabs, with total sales of 10,000 yuan and a profit of 5,000 yuan per mu.

螃crab (páng xiè): Animalia, phylum Arthropods, Crustacea, Molluscs, True Softnails, Decapods, Ventral Embryos, Brachycda. It is a crustacean whose body is protected by a hard shell and breathes by its gills.

Taxonomicly, it is the same animal as shrimp, lobster, and hermit crab.

The vast majority of species of crabs live in the sea or near the sea, but some inhabit freshwater or land. They rely on female crabs to give birth to baby crabs, and each time the female crab lays a large number of eggs, the number of which can reach more than millions. Crabs rely on the geomagnetic field to determine direction.

The genetic material of such organisms is complex and highly varied, often as many as more than 100 pairs. Common crabs include hairy crabs (river crabs, hairy crabs, clear water crabs), pike crabs, etc. The resources of crabs in China are very abundant, among which the hairy crabs of Gucheng Lake, Taihu Lake, Gaoyou Lake, Yangcheng Lake, Hairy Crabs, Xinghua Hairy Crabs, and Hongze Lake Hairy Crabs in the lower reaches of the Yangtze River are the top quality.

(1) Crab breeding. In order to improve the survival of juvenile crabs and increase economic benefits, it is necessary to breed buckle crabs first. 15-20 days before the crab seedlings, 75 kg of quicklime per mu is sprinkled with disinfection, and after the medicinal properties disappear, the water is fed with an 80-mesh filter screen, the basic bait is cultivated, the aquatic plants are transplanted (must be strictly disinfected), and the necessary anti-escape facilities are set up.

2) Adult crab farming.

Adult crabs like the water environment with clean water quality and greater transparency, the aquatic weeds are thick, the bait is abundant, and the growth of river crabs is the most suitable.

Most of them are farmed by eating sugar, choose the right crab seedlings for farming, and pay attention to the quality of the water in the pond.

When raising crabs, it is necessary to ensure that the light is sufficient to reach the total area of the pond, and the size is controlled at 1500 around 1 mu according to the total number of plantings by itself, but reasonable adjustment. The water level is controlled at more than 1 meter, and the surrounding area is hilly terrain, and the soil and stones embedded in the middle are convenient for crabs to rest. Crabs have a habit of burrowing, and in order to prevent them from escaping, the subgrade soil layer must be thicker, preferably isolated by hard chemicals.

Surrounded by a net to protect to avoid crabs escaping, an extra layer of nets should be set in summer, because the probability of crabs escaping is the largest in summer.

Crab seedlings with sound limbs are excellent, followed by attention to their vitality, low vitality of crabs fattening effect will be much worse. It is best not to choose some crab seedlings with abnormal hues, because it is impossible to distinguish between their advantages and disadvantages, and there is no need to take this safety risk without their own rights and interests. At the time of transportation, the relative density of crab seedlings should be moderately controlled, and it is okay to sparse a little, so as to avoid the loss caused by squeezing each other halfway.

Before putting it into the pond, it must be disinfected and sterilized to reduce the pathogenic bacteria it carries, and the seedlings can be gradually cast around the vernal equinox.

Nowadays, the types of concentrate feed of crabs are all fed with milk powder, and the actual effect of a single concentrate feed is not as high as the quality of the mixture. Plants such as corn flour, sweet potato powder, etc., animals can be classified as some small fish and shrimp scraps, snails and other seafood residues, and finally need to put some professional concentrate feed on time. If you want to fill in the nutrients, you can also choose to mix some feed and the like in the middle.

The key is to put in two time ranges in the morning and evening every day, and the crabs are relatively active in this time range, about 40% of the total output in the morning, and about 60% of the amount at night.

Water quality has a great impact on crabs, and to a certain extent, it affects the growth rate and survival rate of crabs. The higher the temperature, the heavier the water depth needs to be, so that it can achieve a certain practical effect of reducing heat. The frequency of water change in the fish tank is determined according to the total area of feeding, the control of the reservoir is about a week, and the large-scale cultivation is controlled once in 1-2 months, if the water quality is good, it can even be changed without the fish tank.

When the light yellow color of the water becomes more and more significant, it is necessary to change someone, and it is best to maintain the water quality condition regularly.

The outlook is so-so. River crab actually refers to a delicacy made with pike crab as the main ingredient, usually most of the crabs that people eat are artificially bred in lakes and ponds, that is, lake crabs, and those that grow in the river are called river crabs.

The development prospects are very good, and now people also like to eat some seafood products, and they also like to eat this kind of river crab very much, so it can meet some of people's needs, so it can also make a lot of money.
