Innovative aquaponics system frugal with fluids

As global demand for food rises, the focus on water resources will intensify. In Berlin, a four-year research project is demonstrating the feasibility of aquaponics, which can drastically cut water inputs. 


An engineer’s design for a classroom aquaculture-aquaponics system

An aquaponics teaching system was designed, built and operated by students at the University of Arizona, integrating its operation and management into the educational curriculum. This engineering design will require minimum maintenance and will last years. 


Young aquaponics, aquaculture company gets big boost

Fluid Farms, an aquaponics produce grower in Maine, leans on multi-trophic aquaculture to provide nutrients for its plants. The company is now selling its hybrid striped bass to the local market and, armed with a $50,000 innovation prize that will 


Aquaponic system produces red drum, saltwater vegetable species

A project in Florida is studying the feasibility of a marine aquaponic system containing red drum and two native saltwater species. Water that exits the plant raceways is filtered and recirculated to the fish tanks. In tests, sea purslane grew

Recirculation meets aquaponics

Today’s aquaculture industry is rapidly adopting recirculating aquaculture systems (RAS) for hatchery and nursery applications. Recently, there has been a move to combine RAS technology with the floating raft aquaponics. 


Integrated marine aquaculture-agriculture: Sea farming out of the sea

Aquaponic systems are robust, management is not difficult, and the synergies between fish and plants make vegetable production more profitable than aquaculture alone. The lion’s share of marine agriculture involves salt-tolerant halophytic plants used as food or feed, or in
