We design, complete and build direct-flow farms for a specific water source, area and type of fish. No standard models - each farm is calculated individually.

Short answer
Flow-through fish farm is a fish farm format designed for a specific site, water source, production capacity and target market. The pool layout, water treatment, oxygen system, automation and auxiliary zones are calculated together, not selected as unrelated equipment. Flow-through farming works when a stable high-quality water source can provide the required flow, temperature and safe discharge conditions.
Briefly about technology
What is a straight-through farm
A flow farm is a farm where water flows continuously from a source, passes through basins or growing channels, and is discharged. Unlike RAS, water does not circulate in a closed circle - it is used once.
Simplicity - in the right place
The main advantage of direct flow is its relative technological simplicity. But it only works with a stable water source.
Critical Parameters
Flow rate, temperature, oxygen, water quality and the possibility of legal discharge. If at least one is not suitable, the project becomes more expensive.
Where is it used?
Trout - in cold, clean reservoirs, sturgeon - in rivers and lakes, warm-water species - in cooling canals.

The basic diagram, requirements for the water source, limitations and nuances of direct flow design are discussed in detail in the “Technology” section.
Clear answers to the questions that usually appear before a RAS fish farm project starts.
What is included in a turnkey flow-through fish farm?
A typical scope includes technology design, tanks or pools, mechanical and biological filtration, pumps, oxygen supply, automation, piping, installation, commissioning and launch support.
Can the farm be adapted to an existing building?
Yes. Before design, the building is checked for area, height, floor loads, water supply, drainage, ventilation, power capacity and convenient equipment maintenance.
What data is needed to calculate the farm?
The first calculation needs the fish species, target capacity, growth stage, available site or building data, water analysis, climate conditions and investment range.
Application
Let's check if direct flow is suitable for your site
Send data on the water and the site - we will check the applicability of direct flow and calculate the technology, equipment composition and economics for your task. If direct flow is not suitable, we will honestly offer an alternative.
Water analysis — preferably in 2–4 seasons
Source flow rate — real minimum consumption
Reset Conditions - where can the water be drained?
You may not know the exact parameters - a general understanding is enough, we will clarify the details during a call.
Calculate a once-through truss
Send data on the water and the site - we will return with an assessment of the applicability of direct flow and calculation of an individual solution for your conditions.
