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. The Crab House not only can be used for breeding, fattening and reserving crab and soft shell crab, but also other benthic aquatic animals.

We  Zhongkehai Recycling Water Aquaculture System CO., Ltd 

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

1, what Crab House consist of?

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  .

2, what’s the building material of Crab House?

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.

3, what’s the size of every crab box?

At present, we supply 2# Crab House with inside size of 32*20*14 cm, which apply for the average aquaculture demand. It is not a problem for  a crab within 500 gram weight to live in. we will invent more types for larger and smaller type crabs in the future.

4, 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.

5, 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.

6,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.

7, 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.

8, What’s the cost of Crab House? How to match water treatment equipment to make it more economic and reasonable?

At present, we sell Crab House as set costs 70,000 RMB 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. Mounting is very ease which can follow the introduction to do. Ten sets of Crab House can be transport by land carriage. If a large order from coastal customer using shipping container, it will reduce much more freight cost.

9, Can one set of recycling water purification equipments support more Crab Houses?

One set of recycling water treatment system can support for 10 groups (1000 boxes) which is design for considering of maximize the equipment processing ability, performance optimization and the principle of risk diversification. In this way, the collocation is both economy and safety.

For example, if we use double process capacity of water treatment equipment to match with 20 groups of Crab House, the cost of water treatment equipment would 2.5 to 3 times higher than the present collocation method and with more energy consumption. Also if one recycling water pump broken because of support too much sets of Crab House, it will highly increase the risk of aquaculture which is opposite with the design purpose of Crab House.
