Why work with MrRak on your RAS farm
Turnkey RAS farm
We take on the entire cycle: feasibility calculations and design, equipment selection and installation, water treatment start-up, stocking, staff training and technology support after commissioning. You receive a farm that is already running, not a pallet of equipment.
Guaranteed buyback in Ukraine
In Ukraine we buy the harvest back ourselves at a fixed price from 10 kg, so a farm owner does not have to chase restaurants or wholesalers. Outside Ukraine this buyback is not offered, and we say so before the project starts rather than after.
Training on a working farm
Two days of hands-on practice on a working farm: feeding, water quality control, moulting, size grading and harvesting. 320 clients have completed this training and now run farms of their own.
Ukraine — and Europe on request
We install and supply anywhere in Ukraine with our own crew and partner network. For projects abroad our technologist travels to European countries, so the launch is supervised on site instead of over a video call.

Simple, step by step
How to start a RAS farm
Consultation and costing
We discuss your budget, the building you have, access to water and power, and your goal: live sales, juveniles or your own processing. Then we calculate the capacity you need and select the equipment set for that site.
Installation and start-up
Our crew comes to the site, assembles the tanks, filtration, aeration and controls, brings the system to its working parameters and hands over a farm that is already in operation.
Training your team
Two days of practice on a working farm: feeding, water control, grading, moulting and harvesting. After that our technologists stay in touch while the farm reaches its design capacity.
Reaching profit
Payback starts from 14 months. One cubic metre of water yields 1–2 kg of product at a stocking density of up to 100 juveniles per cubic metre — these are the figures the whole project is planned around.
