Mini RAS module

It is a complete rearing device, which is intended for beginners who are thinking about breeding fish in RAS, but have no practical experience with fish breeding. It can also be used as a pilot project for aquaculture investors who are considering a serious investment in RAS, but also have no practical experience and would like to try fish farming in RAS.

However, the mini RAS module is a full-fledged rearing device that can be used as a RAS for smaller aquaponics or as a supplementary device for professional breeders.
