China ZHONGKEHAI Recycling Water Aquaculture System Co., Ltd is a high-tech enterprise founded in May 1994, which is specialized in inventing, designing, producing and selling of factory recycling aquaculture system equipments and engineering. Aiming for provide one package service range from equipment manufacturing to installation and commissioning of one set equipment for aquatic laboratory and cultivation on site.

Our products are mainly used for water biological laboratories by universities and research institutions; model biological laboratories by medicine and feed enterprises; factory cultivation workshop of large scale cultivation and nursery habitats.

ZHONGKEHAI always provided customers with advanced technology; integrate design program, strict quality control, professional installation and commissioning, as well as thoughtful after-service based on our own scientific background and strong technical backup force in decades. In order to meet customer demand in all aspects, we also design and produce non-standard and special size products.

In recent years, our company has independently developed series of the water treatment equipment with world advanced level, such as seawater dedicated microfiltration, high speed grit filtration sink, seawater dedicated rotating biological contactor, protein skimmer, super-intensive aquaculture tank, zebra fish rearing system, amphioxus feeding system, ultraviolet disinfection, crab house high density equipment, microcomputer automatic temperature controller and pp cultivation tank and other aquaculture popular products.

ZHONGKEHAI with its professional quality, advanced technology and perfect service has been fully recognized by home and abroad customers and established long-term relationship. To be the first-class enterprises with world brand is always our chasing goal. We sincerely want to establish long-term cooperation with all friends to develop togethe.

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.
