FAQ

What type of fish should I choose?

The system adapts to the following tasks: trout (cold water), catfish (warm), sturgeon (average temperatures).

What is the output?

From 5 to 25 tons per year - depends on the configuration, growing mode and number of modules.

How to maintain the system?

Weekly inspection, cleaning filters, monitoring water parameters. We train staff and provide regulations.

Are licenses needed?

Licensing is required for certain species. We advise and help you prepare documents.
