Standing stock of Antarctic krill (Euphausia superba Dana, 1850) (Euphausiacea) in the Southwest Atlantic sector of the Southern Ocean, 2018–19

Antarctic ecosystem
Biomass
A comprehensive international survey in 2018-19 found Antarctic krill populations remain stable at 62.6 million tonnes - similar to 2000 levels - with no signs of overall decline despite regional variations. The largest survey ever conducted in the Southern Ocean confirms current fishing levels are well below sustainable limits.
