Space Requirement:
Aquaculture section: 11,3 m x 12,2 m
Hydroculture section: 20,0 m x 12,2 m
Total area: 31,3 m x 12,2 m
The length of the hydroculture gives you an annual production capacity of 36,500 salads at year-round production and can be adjust to optimize production or space requirements.
Production Capacity Fish:
The aquaculture section of the system consists of optimized filter tanks,
8 growout tanks (total 23,7 m³ water) and
8 juvenile tanks (total 7,7 m³ water)
Depending on the fish you want to produce, the maximum production capacity varies considerably:
- African Catfish (280 kg/m³ density): 26,9 to p.a.
- Tilapia (100 kg/m³ density): 6,8 to p.a.
Construction Method:
The filter system and the growout tanks are made of concrete and typically are sunk into the ground. The juvenile tanks are build of light material.
Depending on availability, the shading structure and the roof can be made from wooden or metal profiles.
The floor of the hydroculture section can be made of concrete or less solid materials like gravel or laying plates. The hydroponic grow beds are usually made of wood and fitted with liner bags.
Material Costs:
The material costs to build this system can be estimated between 200,000 and 250,000 Euros based on prices achievable in middle Europe.
As many customers build the system themselves, labor is not included in this cost estimation.
Climate / Temperature Conditions:
The system is designed for the usage in the hot areas of the world. The aquaculture and the hydroculture section are built without housing.
A roof and a shading net protect the system from intense sun light and heavy rain. A fence is built to keep predators out.
Annual system input/output:
Fingerlings: 14.211 pcs.
Fish feed: 24.376 kg (for African Catfish)
Freshwater: 747 m³
Electricity: 27,4 MWh
Sludge water: 618 m³
Additives: Small amounts for PH management
