The Importance of Krill

The success of Euphausia superba is not only due to their physiology but also their behaviour. These attributes include: capabilities to locate and effectively exploit food sources in varying habitats, as well as the relationships observed between seasonal successions of food readiness and krill life cycles; for example surviving long winter periods of low food availability (Quetin & Ross, 1991).

Due to these characteristics they are a keystone species within the marine food chain. Not only are they a critical species within the ecosystem, they are being increasingly exploited by anthropogenic means in marine fisheries – for example in the production of krill oil supplements.
