    Abstract

    On the basis of circumstantial evidence, an elevated likelihood exists that Antarctic toothfish and the most-caught by-catch species, macrourids, in the Area 88 fishery are important components in the diet of the Arnoux’s beaked whale (Berardius arnouxii), which is a component of the Ross Sea top predator guild.
