December 16, 2021 — Unchecked global warming could reduce global aquaculture production by as much as 16 percent by 2090, a new study from the University of British Columbia Institute for the Oceans and Fisheries shows.
Marine aquaculture, or mariculture, could double its output by 2050, from a current 30 million metric tons (MT) per year live-weight to 74 million MT, but UBC’s researchers modeled that estimate against climate change scenarios and found climate change to be a more serious threat to the industry than expected.
