Length composition, sex ratio, and pre-spawning migration of Dissostichus eleginoides in Subarea 48.3 during 1995
in 1994/95 took place in two major fishing grounds, West of Shag Rocks (Wshag) and North-West of ... South Georgia (NWSG). In March there was a high proportion of large females at Wshag (72%) but a nearly ... Wshag in April reduced the mean length in the catch and increased CPUE (numbers of fish per hook ... ), although sex ratio remained biassed in favour of females. Similar changes in mean length and CPUE were not ...

Developing robust biomass estimates and advice on catch limits in research blocks
Abstract: In 2016, changes to the methods used by CCAMLR to estimate biomass in research blocks ... resulted in conflicting estimates of biomass between the CPUE by seabed area and the Chapman estimate. The ... different biomass estimates be provided. In this paper, we develop a modified CPUE by seabed area method ... that improves on the original CPUE by seabed area method for toothfish populations in research blocks ...
