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.
Abstract:
The Spanish vessel Tronio started the research plan in the 2012/13 season using the Spanish bottom longline system. One depletion experiments was completed in each of the SSRU surveyed (58.4.1H and 58.4.1G). Three prospecting-phase clusters of sets did not reach the established threshold to start the depletion.
A prospective estimation of the local biomass (BLOC) of the two localized areas where the depletion experiments were performed is done as well as an estimation of the biomass of the SSRUs (BSSRU), maximal and minimal, considering areas with high and low densities.
A summary of the activities and results from the survey is also presented related to the sampling scheme, collected samples and species involved.
