Spatial and temporal variation in krill consumption by the Antarctic fish Notothenia coriiceps, in Admiralty Bay, King George Island
An index of integrated food preferences ( IFA ) of Notothenia coriiceps Richardson at two sites in Admiralty Bay (Ipanema and Smok Point), calculated for two sequential summers, showed that during 1998/99, the most important food item was Euphausia superba (krill) at both Ipanema ( IFA = 0.83) and S...
