Resumen
The length distribution and biological indicators (weight, sex, maturity phases and nutrition indicators) of Antarctic krill obtained during the Russian complex survey on the RV "Atlantida" in January-March 2020 are shown. Analysis is based on 179 standard double oblique tows with research trawl. The length distribution and biological indicators were analyzed by strata including the South Shetland Islands stratum (SSI), the Bransfield Strait stratum (BS), the Elephant Island and the Joinvile Island strata (EI), the Scotia Sea stratum (SS). The catch basis was formed by mature and post-spawning krill individuals, females of stage IIIA and IIIE, males of stage-IIIB.
