DEVELOPING FOUR PLAUSIBLE PARAMETERISATIONS OF FOOSA (A SO-CALLED REFERENCE SET OF PARAMETERISATIONS) BY CONDITIONING THE MODEL ON A CALENDAR OF EVENTS THAT DESCRIBES CHANGES IN THE ABUNDANCES OF KRILL AND THEIR PREDATORS IN THE SCOTIA SEA
with the agreed calendar, as specified by the WG-SAM, that describes changes in the abundances of krill ... and their predators in the Scotia Sea. First, we compiled a set of base parameterizations from ... information in the literature and following specifications laid out by the WG-SAM. These base ... parameterizations cover a combinatorial framework that considers krill movement (or lack thereof) and the shape of a ...

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 ...

The annual random stratified trawl survey to estimate the abundance of Dissostichus eleginoides and Champsocephalus gunnari in the Heard Island region (Division 58.5.2) for 2012
Abstract: The annual random stratified trawl survey at HIMI was completed in March to May of 2012 ... . A codend liner, usually in place for the entire survey, was used only in the icefish strata, Gunnari ... Ridge, Plateau Southeast and Plateau West, and in a repeat of the hauls in Ground B. Catches in this ... RSTS were generally high in comparison with previous years, with the total fish catch being twice as ...

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 ...
