Abstract: Antarctic krill is a key organism in the Southern Ocean ecosystem, connecting the upper and lower trophic levels, has important ecological value. At the same time, it maintains the main fishery in the Southern Ocean, which has high economic value. Antarctic krill is highly dependent on the environment, and the environmental changes brought by global climate change in recent years have brought unprecedented pressure on Antarctic krill resources. Using multi-source data and comprehensive methods to explore the changes of krill resources and their relationship with the environment under climate change will help better understand the resilience of krill ecosystem and support future resource management. This report mainly introduces the comprehensive multi-source data, the use of Integrated Size-Structured model to do krill stock assessment, the comprehensive use of Gradient Forest Model, GAM and other methods to explore how climate change affects krill resources and so on.
