At its 2011 meeting, the Scientific Committee agreed that a time series of relative abundance from a well-designed survey could be a useful input into the Ross Sea stock assessment model. The first survey was completed in February (Hanchet al. 2012a). In this paper we provide the results of the second survey in the time series.
The objectives of this second survey were:
To carry out a longline survey to monitor subadult toothfish in the southern Ross Sea (strata A–C) using standardised gear in a standardised manner; and
To sample additional experimental stations in adjacent areas to identify areas of high subadult abundance which could be included as strata in future annual surveys.
Abstract:
A research proposal to continue the southern Ross Sea subadult toothfish survey is presented. The survey will focus on estimating relative abundance in the core strata (A, B, C) in SSRUs 88.1 J and 88.1L, and will conduct exploratory sets in a newly defined stratum I in southern SSRU 88.1 M. Survey timing and methods will remain the same as in previous years, although the number of sets is proposed to be reduced by 5 sets to a total of 60 sets.

Abstract:
A retrospective analysis and sensitivity evaluation of the performance of the CCAMLR harvest control rule for the mackerel icefish (Champsocephalus gunnari) in Subarea 48.3 are described. The review indicates that the approach is providing consistent, precautionary estimates of future biomass and potential catches. As required to conform to the CCAMLR objectives the harvest control rule generates low levels of exploitation that are considered precautionary and would conform to the ecosystem approach by having an almost negligible impact on the stock.

Abstract:
The Workshop for the Analysis on the Anomalously High CPUE by Korean Vessels in the CCAMLR Area, organized by the Ministry of Oceans and Fisheries of Korea with the assistance of the CCAMLR Secretariat, took place from April 29th to May 1st, 2013 in Busan, Korea. Key issues raised and future work suggested at the Workshop are described in the report.
