Rainbow trout attain good growth, health in tank-based recirculating systems

Circular tank-based recirculating aquaculture systems can be used to effectively culture rainbow trout and other salmonids in a bio-secure and environmentally friendly manner that imposes a much lower water and wastewater footprint than traditional flow-through culture technologies.

Low-space bioreactors remove ammonia in recirculating systems

Despite their relatively small footprint, low-space bioreactors deliver sustainable and cost-effective biological wastewater treatment, particularly in recirculating aquaculture systems, where ammonia removal is critical.
