The shift of phosphorus transfers in global fisheries and

Abstract

Global fish production (capture and aquaculture) has significantly increased, altering global phosphorus (P) flows. In 2016, aquaculture used 2.04 Tg P yr−1, while 1.10 Tg P yr−1 was removed through fish harvesting. Between 1950 and 1986, P shifted from aquatic to land-human systems, peaking at 0.54 Tg P yr−1. After 1986, this flux reversed, becoming negative around 2004. To achieve balanced anthropogenic P flow by 2050, aquaculture phosphorus use efficiency needs to increase from 20% to at least 48%, a significant challenge.
