Tilapia aquaculture has expanded significantly in the last 30 years. Production systems range from extensive, low-density and low-technology in small earthen ponds, to semi-intensive systems in larger ponds, to recirculating systems with high densities.
The potential shrimp aquaculture has for significant improvements in performance through improved genetics and nutrition will not be fully expressed unless appropriate feeding methods are practiced.
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.
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.
Recirculating systems, where probiotic, heterotrophic bacteria compete with pathogenic bacteria, can operate without antibiotics to produce tilapia and shrimp.
