Phytoremediation for nutrient removal in an environmentally friendly floating cage system: a field experiment

Aquaculture is one of the efforts to optimize the utilization of water bodies. Aquaculture using floating net cages is detrimental to water, namely causing pollution from uneaten feed and fish excretion. Water quality would be degraded due to eutrophication, oxygen depletion, and uncontrolled growth...

Aquaculture using floating net cages is detrimental to water, namely causing pollution from uneaten feed and fish excretion.

High concentrations of nitrogen and phosphorus mainly trigger water quality degradation and eutrophication.

The technology offered is a loop bio-phytoremediation system equipped with floating net cages, a water management system with recirculation, and plants.
