Aquaculture soft shell crab

Product Description


  The Crab House is an indoor factory aquaculture equipment using recycling water for breeding crab and soft shell crab, which is exclusive studied, invented and produced by China Zhongkehai Recycling Water Aquaculture System CO., Ltd which owned the independent knowledge property right.

  Crab is an aggressive creature which will cause a certain loss if they are breeding together because they will fight and kill each other, especially when shelling.

  Crab House provide separate aquaculture box for each crab, equipped with supplying and exhausting water system and increasing oxygen into water function. It can automatically discharge faeces and remnant bait (self-clean patent design) to maintain a good quality water environment in each box. When it needs thoroughly clean, each Crab House can drain all the water completely. Each Crab House has a door to prevent the crab escape. The conveniently open and lock mechanism and a observation window on the door make staff check crabs without opening the door, which greatly saves manpower and time at the same time to minimize the impact on stress responding of aquaculture creature.

  Crab House can be free combined into different floors and different boxes each floor according to customer demand (usually one set consist of 10 floors which has 10 boxes each). Each set can do water treatment separately (suitable for small scale aquaculture or experiment lab), also can collect all return water for treatment together (suitable for factory aquaculture).

  Crab House saves much more land (if breeding 100 crabs calculating as 400 grams each on average, the ordinary pool for aquaculture covers about 300 square meter, while Crab House only covers net 0.9 square meter area, which improve the land utilization ratio of 300 times. For inland area and far away form the sea, it is also easy to cultivate seawater crab breeding.     Crab House consumes less water, save energy and heating and cooling rapidly.

  Crab House effectively evade most of the risk and uncertain factors (climate risk-indoor breeding, water quality risk- sterilized and purified recycling water, eliminate other biological causing pathogenic disease risk- single specie breeding in single box) during aquaculture.

  Crab House use less manpower (one skilled worker can raise 2,000 to 5,000 crabs) to realize intensive full-year production of high density aquaculture.

  Crab House can make more economic profits for reserving and breeding soft shell crabs. The same size and specie of soft shell crab with short aquaculture cycle (3 to 15 days usually) is 4 times more expensive than ordinary one.

  Crab House advocates green, pollution-free and organic ecological aquaculture without chemical of catalytic and ripening in order to achieve environmental health and safety.

Soft shell crabs aquaculture is a new hot business. Crab House will be the best choice for soft shell crabs aquaculture.

the product feature

Crab House consisted of many groups with ten floors and each floor has ten boxes, which is one hundred boxes totally for one group. Every group is equipped with a recycling water aquaculture system including high speed grit filter tank and UV Sanitiser  .


Crab House is made from a new food grade pp (polypropylene) material with fine workmanship by injection moulding, the same material of house used microwave lunch box. This material is a healthy and non-toxic material which is wide used in food industry and this food safety standard material has already been applied in Hong Kong and the west.


At present, we supply M Crab House with inside size of 32*20*14 cm and L Crab House with inside size of 42*27*18cm. The M Crab House is not a problem for  a crab within 500 gram weight to live in. The L Crab House is not a problem for  a crab within 1000 gram weight to live in.




1,What’s the environment requirements of Crab House?

We suggest of indoor breeding which can easily control all water quality indexes and better temperature insulation for energy saving.

Production oriented Crab House needs a pool or tank under the ground for collecting return water and a base of Crab House which can be made of bricks or stones according to the demand of instruction manual.

2,What’s the water consumption of each group of Crab House?

Every set of Crab House consume around 5 tons water. We suggest replacing 5-10% new water every day to make sure the water quality and temperature stability in a low cost level.

3,How to feed crabs using Crab House?

Breed each crab in each box separately every day with sterilized fish, shrimp and low-value shellfish using Crab House.

4,How to clean up the remnant bait and feces during the aquaculture?

The drainage system with patent technology can automatically discharge the remnant bait and feces with waterout Crab House. There is no need manual cleaning every day but only taking out the leftover large empty shells, if not, it also won’t pollute the water.

5,Will diseases happen to Crab House aquaculture mode?

Diseases rarely happen to Crab House since the water has been filtered and sterilized. Even if one crabgets sick, it will not infect to other crabs. Diseases will hardly happen, if we pay more attention to sterilize bait and container regularly.

6,How long can it be used of Crab House?

Crab House is made from a new ageing resistance macromolecule material with food grade. Normally, it can be used more than 10 years.

7,Do your company provide the aquaculture technology of soft shell crab?

We can provide the relevant aquaculture technology information of the soft shell crab.

8,Which kind of water purification equipments need to possess?

As usual, we suggest the user to use the following equipments to process water: 1. A microfiltration and a High speed grit filter tank. 2. A protein skimmer for gas concentration soluble substances (only apply to seawater species). 3. A biological tower or biological packet used for decomposing ammonia and nitrogen and other harmful substances. 4. An equipment using UV sanitiser  to sterilize the water 5. A refrigerator and heating machine for adjusting water temperature in the whole year aquaculture.

9. How is the power and water consumption?

10 groups Crab House (1000 boxes) consume around 880 kilowatt hours every month not including cooler and heating machine. The total water consumption is about 5 tons in which 5 to 10% needs to be change everyday by discharging pollute water used for cleaning sand filter cylinder and supplying new water.

10,Dead crabs is toxic and can not be eaten and soft shell crabs are dead crabs Is soft shell crab toxic?

Crabs live in water feeding with dead fish and shrimp and other corruption animal bodies, which will make crab infect with certain bacteria in their bodies. Especially river crabs, they living in polluted rivers obtains a large number of bacteria inside and outside of their bodies. Live crabs can discharge the bacteria out of their bodies through metabolizing but once they were died, the bacteria inside the body will multiply and decompose crab meat and some bacteria is toxic. In addition, the crab body contains more histamine which is easy to be decomposed; especially the decomposition speed is quicker after crab died. The longer time crab died, the more histidine they have. When the number of histidine up to a certain level, it will cause people poisoned if they were eaten. The common symptoms are nausea, vomiting, abdominal pain and diarrhea; seriously with dehydration, electrolyte imbalance, convulsions and even shock, coma, and sepsis and so on.

But these soft shell crabs are quick-freeze in super low temperature when whey are alive (of course they are alive when shelling). It is the same like the crab is steamed when they are alive, that is to say, the bacteria in soft shell crab hasn’t been discharged when they are frozen. It is as safety as eating alive crabs.
