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 ...
