Variants of the ASPM assessment of the toothfish (Dissostichus eleginoides) resource in the Prince Edward Islands vicinity which attempt to reconcile CPUE and catch-at-length data
Abstract: Two variants of the ASPM assessment of the Prince Edward Islands toothfish resource are ... examined. One allows for the possibility of changes in somatic growth rate in response to increased food ... availability as resource abundance drops. The other permits annual fluctuations about a deterministic stock ... -recruitment relationship. A fit of the first variant yields the biologically implausible result of a decrease ...

Progress towards a trophic model of the ecosystem of the Ross Sea, Antarctica, for investigating effects of the Antarctic toothfish fishery
Abstract: We report on the further development of a carbon-budget trophic-model of the Ross Sea ... with which to investigate effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The ... Ross Sea is a low primary production system, with production being localised in space and time. In the ... relative absence of krill, Antarctic silverfish (Pleuragramma antarctica) are probably the major middle ...
