The Crab Farming Box is a modern indoor aquaculture solution designed for high-density and controlled breeding environments. Manufactured by a professional China factory, this system is widely used in RAS (Recirculating Aquaculture System) projects for crabs, lobsters, fish, and soft shell crab farming. It is engineered to replace traditional pond farming and open-water aquaculture, which often suffer from low survival rates and unstable water conditions.
As a plastic aquaculture Crab Box, each unit provides an independent breeding space, ensuring stable water quality and reducing disease transmission between animals. This makes it an ideal solution for commercial indoor farming, research labs, and factory-scale aquaculture operations.

The Plastic Crab Box is made from high-quality PP material, offering strong durability, corrosion resistance, and long service life in continuous water circulation environments. With a compact size of 42×34×18cm, it is suitable for crabs, lobsters, and fish breeding in vertical farming systems.
Product name: Plastic Crab Farming Box
Material: PP (Polypropylene)
Size: 42 × 34 × 18 cm
Application: Crabs, fish, lobster, soft shell crab farming
System compatibility: Indoor vertical RAS aquaculture system
The Crab Box for Indoor Farming is designed to significantly improve survival rate and farming efficiency by optimizing environmental control and reducing risk factors.
Each crab is raised in a separate box, effectively eliminating disease cross-infection and reducing biological contamination risks.
The system is equipped with:
Water supply and drainage channels
Oxygenation system
Automatic waste discharge (feces and residual feed removal)
This ensures stable and clean water quality in each unit.
The Crab Farming Box House adopts a self-cleaning structure that helps maintain water clarity and reduces labor costs. When needed, each unit can be fully drained for deep cleaning.
Each box includes a secure door to prevent crab escape, along with a transparent observation window. Operators can monitor crab conditions without opening the box, reducing stress and improving efficiency.
The Soft Shell Crab Farming Box with RAS system is especially suitable for high-value aquaculture production. Compared with traditional farming methods, soft shell crab breeding in controlled environments can significantly increase profitability.
Short breeding cycle (typically 3–15 days)
Higher market value (up to 4× compared to normal crabs)
Stable production quality and size consistency
The Crab Box House system is designed for industrial-scale aquaculture operations. It supports modular combination and flexible system design:
Multi-layer vertical structure (commonly 10 floors, 10 boxes per layer)
Independent or centralized water treatment system
Suitable for both laboratory testing and large-scale factory farming
Scalable design for different production capacities
This flexible structure allows farmers to optimize space usage while maximizing output efficiency.
Using the Plastic Crab Box aquaculture system brings several key advantages:
Lower labor cost (1 skilled worker can manage 2,000–5,000 crabs)
Higher survival rate compared to traditional pond farming
Reduced disease risk and improved biosecurity
Year-round controlled production environment
Higher economic return from soft shell crab farming
The Crab Farming Box for RAS system is an advanced solution for modern indoor aquaculture. With its modular design, independent breeding structure, and efficient water circulation system, it provides a stable and high-yield environment for commercial crab and lobster farming.
Whether used for vertical aquaculture systems, factory farming, or research applications, the Plastic Crab Box House system delivers improved efficiency, reduced risk, and higher profitability for aquaculture businesses.
A Crab Farming Box is an indoor aquaculture unit designed for raising crabs in a controlled environment, especially in RAS (Recirculating Aquaculture System). Each box provides an independent space for single-crab breeding to improve survival rate and reduce disease risk.
Compared with traditional pond or sea farming, the Plastic Crab Box system offers:
Independent breeding to prevent disease spread
Stable and purified water quality through RAS
Higher survival rate and faster growth cycle
More controlled and predictable production
The Plastic Crab Box is made of high-quality PP (Polypropylene) material, which is:
Corrosion-resistant
Durable in water circulation systems
Safe for aquatic breeding environments
Long service life with low maintenance
The system is suitable for:
Crabs (including mud crab)
Soft shell crabs
Lobsters
Small fish species
It is widely used in indoor vertical aquaculture systems.
The RAS system (Recirculating Aquaculture System) continuously:
Filters and purifies water
Removes waste and ammonia
Supplies oxygenated water
Recycles clean water back into the system
Each Crab Box is connected to this circulation system for stable water conditions.
Yes. Each unit has a drainage and self-cleaning design, allowing operators to:
Fully drain water when needed
Remove waste automatically
Clean individual boxes without shutting down the whole system
The Crab Box House system uses a multi-layer vertical structure, which:
Saves space for indoor farming
Supports high-density production
Allows flexible system scaling
Can be configured for lab or factory use
With this system, one skilled worker can manage approximately 2,000 to 5,000 crabs, depending on system size and automation level.
