Phosphorous recovery from a novel recirculating aquaculture system followed by its sustainable reuse as a fertilizer

Abstract Phosphorus (P) is an essential element for life that is introduced through feed in modern aquaculture—the fastest growing food production sector. P can also be a source of environmental contamination and eutrophication if mistreated. Fish assimilate only 20–40% of the applied P; the rest is released into the water. The goals of this research were to study the fate of P in a novel intensive near-zero discharge (
