The Crab House is indoor factory aquaculture equipment using recycling water for breeding crab and soft shell crab fattening, which is exclusive, studied, invented and produced by OSMOSIA Water Technology 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. Modern method of indoor RAS crab farming is increasing day by day in Bangladesh.
Crab House Box consisted of many groups with ten floors each and every floor has ten boxes that is one hundred boxes totally for one group. Every group is equipped with a water treatment system using recycling filtering disinfectant fluid. OSMOSIA Company fully cooperates with Indoor Vertical RAS Crab Farming Project
Crab House Box is made from a new food grade pp (polypropylene) material with fine workmanship by infection model, 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. Provides vertical indoor RAS crab farming houses and other equipment at low prices in Bangladesh.
At present, we supply for 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.
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 purified water equipment). Accounting as every 50 groups (breeding 5000 crabs at the same time), it only needs a house covers an area of 150 square meter.
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. The southern saline areas of Bangladesh have huge potential areas for indoor crab farming.
Crab House is an indoor factory stereo aquaculture using recycling water equipment which designed for avoiding conventional breeding pattern of low survival rate and higher risk, such as ordinary pound farming, the sea aquaculture and large indoor pool aquaculture. In the process of breeding, it will not change the life habits and growth principle of crabs because Crab House’s breeding pattern has not much different with traditional breeding mode, though it might shorter the growth cycle, it is not that obvious.
We just separate crabs for avoiding of the killing each other in order to improve survival rate. This factory recycling water treatment system provide good quality water temperature conditions for crabs to make them grow better and avoiding diseases and water quality deterioration which will influence the production. Also indoor aquaculture can evade a lot of natural disaster climate 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.
Crab House is much more suitable for breeding soft shell crabs and we will support the technical guidance. Bangladesh will be the highest level of production from indoor vertical crab farming projects.
At present, we sell Crab House as set costs about 2,000,000 - 3,000,000 BDT which include 10 groups (1000 boxes can breed 1000 crabs), a high speed sand filter cylinder (OSMOSIA-SF), an ultraviolet sterilizer (OSMOSIA-UV) 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 so. 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.
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.
Osmasia Company's 36 inch sand filter with super pressure water pump is the most effective water filtration system for any commercial Recirculating aquaculture system (RAS) crab and shrimp or fish farming projects.
