Crab Box--A convenient farming equipment

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.

At present, we sell Crab House as set which include 10 groups (1000 boxes can breed 1000 crabs), a high speed sand filter cylinder (ZKH-SL1200A), an ultraviolet sterilizer (ZKH-ZW4003) and a water pump. The entire price above doesn’t cover the tax, freight and mounting fee.


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


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. How much area Crab House covers of?

Crab House covers much few area of net 0.9 square meter of every group and around 2-3 square meter of totally area (include walkway and recycling water equipment). Accounting as every 50 groups (breeding 5000 crabs), it only needs a house covers an area of 150 square meter.


2. which kind of crab is apply to Crab House?

No matter which kind of seawater crab or freshwater crab is applied to our Crab House, as long as the size is suitable for using it.

3. How long the growth period of crab using Crab House? Can it apply to inland?

Crab House is an indoor factory stereo aquaculture using recycling water equipment which designed for avoiding the problem low survival rate and higher risk of conventional breeding pattern , such as ordinary pound farming, the sea aquaculture and indoor large pool aquaculture. In the process of breeding, it will not change the  habits and growth principle of crabs, so Crab House’s breeding pattern isnot much different with traditional breeding mode, though it might shorter the growth cycle, it is not that obvious. We just separate crabs for avoiding  they killing each other in order to improve survival rate. This factory recycling water treatment system provide good quality and suitable temperature conditions water for crabs to make them grow better and avoid decline of the production cause by diseases and water quality deterioration . Besides, indoor aquaculture can evade a lot of natural disaster which impact on traditional aquaculture and through means such as temperature control to decide the time to market in advance or delay to make more profits ( this is similar to green house of planting fruits and vegetables).

As for inland area, Crab House can breed seawater and freshwater crabs technically, but seawater crab breeding need to do market research first to see if there are any profits. We suggest that inland company could consider of breeding local crab species or reserving and temporarily raising seawater crab, after all, the cost of breeding seawater crabs in inland is high.


4. Can Crab House breeding soft shell crabs?

Crab House is much more suitable for breeding soft shell crabs and we will support the technical guidance.


5.   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.


6. 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.


7.  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.


8.  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.


9.  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.



10.  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.
