Data on the reproduction, growth, and morphometric characteristics of southern blue whiting (Micromesistius australis Norman) were examined to determine its stock structure in New Zealand waters. Consistent differences in the size distribution of fish, and in the timing of spawning were found between spawning grounds on the Bounty Platform, Pukaki Rise, Auckland Islands Shelf, and Campbell Island Rise. Significant differences...

Dietary samples collected at Campbell Island in summer 1997 indicate that southern blue whiting ( Micromesistius australis ) formed the bulk of the food of black‐browed albatrosses ( Diomedea melanophrys impavida ) during the chick‐rearing period. Birds preyed upon a single size class of fish with a mode at 80–90 mm standard length; fish were 4–5 months old and belonged to the + age group. Satellite tracking showed that, when...
