Project aims

The experimental krill research project is designed to focus on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the project will concentrate on studies into impacts of climate change on key aspects of krill biology and ecology.

The experimental krill research project is designed to focus on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the project will concentrate on studies into impacts of climate change on key aspects of krill biology and ecology. The project assessed the impacts of increasing CO2 level on early life stages of Antarctic krill and its implications to future krill population.

Final Summary of Project Achievements

Antarctic krill is the key species of the Southern Ocean ecosystem. Its fishery is rapidly expanding and it is vulnerable to changes in climate.
This project was designed to focus on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the project focussed on studies into impacts of climate change and ocean acidification on key aspects of krill biology and ecology.
Through this project, we demonstrated embryos of krill are vulnerable to increasing CO2 and is likely to be impacted by CO2 levels expected in 100 to 300 years but adult krill are resilient to CO2 expected in the near future.
