5. DISCRIMINATION OF ENVIRONMENTAL VARIABLES THAT INFLUENCE THE CATCH PER UNIT EFFORT: THE CASE OF THE ANTARCTIC KRILL FISHERY

   Abstract:  The use of the catch per unit effort (CPUE) as an index of abundance usually requires a ... from the CPUE time-series. These exogenous factors include those generated by modifications in fishery ... vessel efficiency, variations in fishing strategies, and environmental fluctuations. The selection of the ... latter has been considered to be one of the most difficult, arbitrary, and poorly documented stages since ...

9. 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 ...
