CC | Cold Climate

Aquaponics System

General Description

The CC | Cold Climate Aquaponics System is designed for the usage in cold areas where the fish area is housed within an insulated and heated building. It is designed with a strong focus on optimized production conditions.

The aquaculture section consists of two separate circuits housed in concrete tanks. Each circuit consists of 4 grow-out tanks, 4 juvenile tanks, two solids filters, and one bio filter. Via the coupling tanks, the water is directed into the hydroponic section, where it flows through the plant beds and finally back into the coupling tanks.

Technical Details

Space Requirement:

Aquaculture section: 13,0 m x 12,5 m

Hydroculture section: 20,2 m x 12,2 m

Total area: 33,2 m x 12,2 m

The length of the hydroculture gives you an annual production capacity of 27,400 salads (9 month 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. The building usually consists of a wooden structure with sandwich panel walls. Alternatively bricks or concrete can be used.

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 300,000 and 350,000 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 areas where the winters are cold and long.

A isolated building reduces the energy loss and by that minimizes the heating costs so that even in winter the production of warm water fish is economically reasonable. The heating system is not part of the implementation documentation.

Annual system input/output:

Fingerlings: 14.211 pcs.
Fish feed: 24.376 kg (for African Catfish)
Freshwater: 747 m³
Electricity: 27,4 MWh (excl. heating)
Sludge water: 618 m³
Additives: Small amounts for PH management
