Outline details of the proposed aerial photographic survey at South Georgia for estimating breeding population sizes of land-based predators
with commercial fisheries. The research will also develop methodologies that reliably assess trends in ... predator populations breeding at South Georgia with a view to providing critical data about interactions ... the abundance of these populations. The research will focus upon predator species that depend upon ... marine resources that are also harvested by commercial fisheries, principally Antarctic krill. It will ...
