Discussion on recent results from an integrated assessment of Antarctic krill (Euphausia superba) in Subarea 48.1
from three of the models provide a robust picture of changes in the krill population. An annual model ... surveys estimated similar absolute biomasses and changes in biomass. A seasonal model estimated similar ... changes in biomass but lower absolute biomasses than the two annual models. A monthly model estimated ... different changes in biomass but predicted absolute biomasses that were similar to those from the seasonal ...
