A new plug-and-play filter system recently launched by Israeli tech company BioFishency will allow smaller-scale and developing-world producers to convert their flow-through systems (FTS) to recirculating aquaculture systems (RAS) virtually overnight.

The BioFishency filter removes carbon dioxide and ammonia from the water and enriches it with oxygen for the nitrification process, converting the ammonia into nitrates, creating a system with very low water demand that is closed from the outside environment.
