A critical issue for feedback management – how do we determine the level of functional overlap between krill fishing operations and penguin foraging activity?
Abstract: The spatial distribution of the Antarctic krill fishery in Subareas 48.1 to 48.3 has ... changed over time. The majority of catches in Subarea 48.1 are now taken south of the South Shetland ... Islands, following regional decreases in seasonal sea-ice cover. As the cumulative spatial footprint of ... the fishery has expanded along the West Antarctic Peninsula, the cumulative numbers of krill-eating ...

Stratification of catch-at-length data using tree based regression: an example using Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea
Abstract: This paper presents a new approach to the stratification of catch-at-length data of ... Antarctic toothfish (D. mawsoni) in the Ross Sea. Tree based regression techniques were used to stratify the ... sampled catch based on the median length of Antarctic toothfish for each set using the observer length ... frequency data. The median lengths were weighted within the regression by the inverse of the variance ...
