New gonad identification guides for Dissostichus eleginoides
Abstract: Difficulties in distinguishing between certain gonad stages is of common concern for observers onboard vessels fishing for Dissostichus eleginoides. To minimise errors in interpretation of maturity scales of D. eleginoides a comprehensive identification guide has been prepared. It is

Preliminary assessment of toothfish in Subarea 48.3
Abstract: As with the 2009 assessment of Subarea 48.3, there is still uncertainty as to why there were high numbers of the 2001 cohort in commercial catches in 2009 onwards. It is likely that it is due to a combination of a strong 2001 cohort and a change in selectivity for the commercial fleet,

Preliminary assessment of mackerel icefish, Champsocephalus gunnari, in Subarea 48.3 using a length based population dynamics modelv
Abstract: A length-based projection model is used to estimate catch limits for the 2011/12 fishing season for Champsocephalus gunnari in CCAMLR sub area 48.3. The model is initialised using estimated numbers at length derived from survey length density and biomass density data, removing the need

Assessment of the Action Plan aimed at reducing incidental catch of seabirds in the French EEZ included in the CCAMLR Division 58.5.1 and Subarea 58.6
Abstract: France presented at CCAMLR XXVII an action plan aimed at reducing incidental avian mortality by 50% in the French EEZ included in the statistic division and subarea 58.5.1 and 58.6 for the period 2008/2009 to 2010/2011. The aim of this document is to present the various measures

Research standards for exploratory fisheries
Abstract: The potential for data poor exploratory fisheries in the CAMLR Convention area to provide sufficient data to lead to formal stock assessments of Dissostichus spp. is evaluated and recommendations are made for optimizing this potential. The types of data that have led to successful

SEASONAL ESTIMATION OF ABUNDANCE BY BOOTSTRAPPING INEXACT RESEARCH DATA (SEABIRD): A METHOD FOR ASSESSING ABUNDANCE AND UNCERTAINTY FROM HISTORICAL COUNT DATA USING ADELIE PENGUINS AS A CASE STUDY
Abstract: In addition to a review of published studies on Adelie penguin abundance at breeding sites in Antarctica, Southwell (2004) proposed a general abundance estimator appropriate for a species of that kind. The present study attempts to implement this estimator in the form of a parametric

Krill population trends
Abstract: Krill (Euphausia superba) distribution and abundance data are available from a number of sources: from net surveys (the longest historical series of available date), from acoustic surveys, from fisheries data and from the distribution of krill predators. Each of these forms of data
