Collect krill samples using IKMT nets for oblique trawling in each experimental area. After returning to the terrestrial laboratory, the krill samples were counted and weighed, and the sex periods, body length, and eye diameter of krill samples from several stations with higher abundance were measured to understand the growth status of krill in the Southern Ocean. This data set is the biomass survey data of Antarctic krill during the 21st, 22nd, 24th and 25th China Antarctic Expeditions
