Reconstruction and modernization of RAS fish farms
We work with existing facilities: we eliminate technological errors, adapt the premises for fish farming, replace outdated components and bring the farm to design parameters. The format ranges from a one-time visit with an expert opinion to a reconstruction project, equipment supply and implementation support.
Fish farm reconstruction and modernization helps fix the technical logic of a fish farm before major spending on construction or equipment. It reduces redesign risk and gives a clear implementation path. Reconstruction improves capacity, fixes weak water treatment points and adapts an existing facility to a new production target.
Situation
Current situation
Operating farms and premises adapted for fish farming often face the same problems: the system does not reach its designed capacity, the water quality is unstable, individual components are calculated or installed incorrectly, and there is no safety margin.
In such cases, what is needed is not a spot replacement, but a technical check of the entire facility: on-site inspection, measurements, calculated re-checking of components, identification of bottlenecks and a step-by-step correction plan.
What the survey shows in practiceTypical problems: insufficient mechanical and biological treatment, lack of disinfection and oxygenation, lack of backup pumps, errors in degassing, unsuccessful adaptation of the building. An example from one conclusion: mechanical cleaning - 36% of the required power, biological - 25-40%, oxygenation - 65%, disinfection - 10-20%.

Process
Work plan
The set of stages depends on the initial situation: sometimes a visit and conclusion is enough, sometimes a complete reconstruction with a project, replacement of equipment and support is needed.
Stage
What we do
Result
1. Collection of initial data
We study the task, the condition of the facility, the composition of the equipment, complaints about operation, floor plans and measurements.
Scope of the survey and list of initial data.
2. Departure and inspection
Inspection of the premises, tanks, operating units, communications and equipment layout.
Understanding the actual configuration and limitations.
3. Measurements and calculation check
We check hydraulics, water quality, purification units, oxygenation, disinfection, redundancy, and layout.
List of bottlenecks and actual power limitations.
4. Written opinion
We record problems, their causes and the degree of impact on the operation of the farm.
Ready expert opinion for decision making.
5. Correction plan
Technical solutions: replacement of components, retrofitting, phased modernization, conversion to RAS.
A clear plan of action for reconstruction.
6. Project stage
If necessary, a reconstruction project, working documentation, and a list of equipment.
Documentation for the implementation of work.
7. Implementation
Supply and installation of equipment, commissioning and implementation support.
Entry into operational operation and target parameters.

Reconstruction, modernization and audit of existing fish farming facilities.
Georgia, Batumi
Reconstruction of sturgeon recirculation system - 50 tons of marketable fish per year, 2400 m². Water treatment and recycling system, 24 pools of 40 m³ each and pre-sale preparation pools.
MO, village Aprelevka
Modernization of the African catfish farm - up to 20 tons/year, 150 m². Replacement of water treatment units and return to design capacity.
KHMAO-Yugra, Khanty-Mansiysk
Reconstruction and retrofitting of the sturgeon complex: design, production of equipment, installation, commissioning and commissioning.
Chelyabinsk region, Miass
Modernization of a trout farm: design work, working documentation, production and installation of equipment, commissioning.

Examples of examinations and conclusions
What the result might look like: a conclusion on the object, conclusions on the condition and a step-by-step correction plan.
Borisoglebsk · former treatment plants
Of the existing structures, it is advisable to use only open concrete pools. Concrete repair, replacement of pipelines, membrane coating and insulated hangar 25x26 m. Step by step: 1st stage - up to 25 tons of trout and 20 tons of sturgeon; 2nd stage - up to 50 tons of trout.
Voronezh hangar with canals
The dimensions of the room are suitable for RAS, but require insulation, vapor barrier and new floors. Concrete channels - with reservations, free areas - for expansion. 3 stages: from “Aquafarmer-800” to channel integration.
MO · private plot
The former bathhouse is not suitable for RAS pools, but is suitable for auxiliary functions. The site allows you to place a workshop and the Aquafarmer-2500 installation for up to 2.5 tons of sturgeon/year. We need water analysis from the well and drainage testing.
Batumi · operating RAS
Layout errors were identified: inoperative biofilter, insufficient degassing, issues with fur. cleaning and UV. The goal is to correct and increase the capacity from 50 to 60 tons of sturgeon/year. 2 stages are recommended.

The next step is delivery and installation
After the inspection, approval of the technical solution and scope of work, we proceed to the supply and installation of process equipment with commissioning and implementation support.
Clear answers to the questions that usually appear before a RAS fish farm project starts.
When do you need fish farm reconstruction and modernization?
It is useful before buying equipment, starting construction, renovating an existing farm or launching a new production line, when an engineering mistake can be expensive.
Can the work start remotely?
Yes. Initial review, calculations and consultations can start from drawings, photos, videos, water analysis and a questionnaire. Site visits are added when they are technically necessary.
What should be prepared before the first discussion?
Prepare the target fish species, planned capacity, country or region, site or building data, water source, available utilities, existing drawings and business goals.
