Antarctic krill (Euphausia superba) plays a vital role in the Southern Ocean ecosystem, serving as a key link between primary producers and higher trophic levels. This study investigates the correlation between Antarctic krill density and environmental variables, including sea surface temperature, chlorophyll concentration, and mixed layer depth, using Pearson’s correlation coefficient and fuzzy entropy analysis. Data from the KRILLBASE and GLORYS2v4 databases were analyzed, focusing on the period from 2010 to 2016. Results reveal that sea bottom temperature and mixed layer depth significantly influence krill distribution, while nutrient-related variables indirectly affect abundance. Fuzzy entropy identified 195.0 meters as the optimal depth for krill habitat, characterized by stable environmental conditions. These findings provide insights into krill ecology and support sustainable management of Antarctic marine resources.
