Abstract: 

As a contribution to the work program of WG-EMM-STAPP to estimate krill consumption by predators, this paper presents estimates of krill consumption by crabeater seals off East Antarctica between 64ºE-150ºE, which includes all of Division 58.4.1 and part of Division 58.4.2. Krill consumption by crabeater seals in this region in 1999/00 was estimated to be 3.8 (95% CI 2.4-6.0) million tonnes per year. This represents approximately 20% of the krill biomass estimated from acoustic surveys.
