Rectangular polygons indicate the research blocks, each approximately 23 500 km2 153 km 153 km.
The Working Group discussed the different reasons as to why research could not be completed in the research blocks.
Table 1: Agreed reference areas for species and research blocks in Subareas 48.6 and 58.4.
The Working Group noted that the method was considered an interim measure for the calculation of precautionary catch limits in research blocks.
Eleginoides in research blocks in Subareas 48.6 and 58.4 as agreed by the Scientific Committee SC-CAMLR-XXXV, Annex 5, paragraph 2.28.
The Working Group noted thatrecovery of tagged fish, and therefore biomass estimation, was most likely in research blocks 883_3, 883_4 and 883_5.
Mawsoni(TOA) in research blocks, catch reported in 2014, number of tagged fish available and the expected and observed recaptures.
The Working Group considered the choice of reference areas chosen for research blocks(WG-SAM-16/18 Rev. 1, Appendix 3, Table A3) and agreed that for.
Several Members requested some flexibility in their research for situations when ice restricted access to research blocks.
It noted the analyses conducted by WG-FSA that indicated that research blocks are most likely to be ice-free in February e.g. Annex 7, Figure 12.
In some years, other research blocks were partly or entirely occluded by sea-ice, however, February was consistently the month that sea-ice was at its minimum extent.
It further noted that it was a good case study for the transition from local area estimates of biomass in research blocks to the assessment of stock size.
The Working Group recognised that fishing in research blocks 883_1 and 883_2 could provide information to inform a stock structure hypothesis but was unlikely to contribute to biomass assessment.
The proponents recognised that recapturing tagged fishwas the highest priority, particularly in research blocks 883_3 to 883_5, which are typically more accessible.
The proponents developed an approach to review research blocks based on the number of tagged fish available, ice conditions and a series of other parameters to identify the best locations to further progress a stock assessment.
The flowchart also makes explicit the annual review process within each phase,indicating that individual research blocks may remain in a single phase for more than one year.
The proposed research is located within existing research blocks, however, details relating to accessibility of these areas during times when the proposed research will be conducted are missing from the research plan.
The Working Group agreed that the focus of research should be on efforts to resolve the movements of fish between research blocks and to improve the tag-recapture rate.
The Working Group noted that additional analyses of historical ice conditions in these research blocks(see also WG-FSA-13/37) and of likely CVs of local biomass estimates associated with different numbers of recaptures, were informative.
The Working Group recalled the advice of WG-SAM-18(Annex 6, paragraphs 4.1 to 4.7)to use the linear trend method for the estimates of local biomass in research blocks in Subareas 48.6 and 58.4.
The Working Group noted that research fishing conducted outside the research blocks would provide little useful additional information on stock abundance.
As such, the Working Group acknowledged that new methods andstrategies will be required to incorporate consideration of future proposals that endeavour to undertake research fishing outside of existing research blocks.
The Working Group noted that the proposals by Spain, and Japan andthe Republic of Korea, both included research blocks located in areas that are periodically covered by sea-ice.
The Working Group noted that effort in four research blocks and tagging efforts appear to be yielding encouraging results, with a total of 42 tagged toothfish having been recaptured during the first 19 months of the research program.
It noted that without data to test the stock hypothesis it was not clear how the transition from estimation of biomass within research blocks to an integrated assessment for the whole subarea would be achieved.
The Working Group recommended the approach be used with a slope value of± 0.1, noting no change in the slope determination as a result of biomass CVs of 0.2 or 0 andthat this method be used to provide management advice for setting catch limits in research blocks.
Japan and the Republic of Korea shall conduct research fishing in the research blocks defined in Annex 41-11/A, and Spain shall conduct depletion experiments in SSRUs C, D, G and H.
The Working Group agreed that following the confirmation of the detailed methods to be used to produce the biomass estimates(paragraph 2.28),the Secretariat be requested to produce the biomass estimates for all research blocks in Subareas 48.6 and 58.4 and to present these to WG-FSA-16.
The Working Group requested that estimates of the biomass for other proposed research blocks included in research proposals also be calculated by the Secretariat using the same methods.
Dr Kasatkina expressed concern about the calculation of the catch limit for the researches in Division 58.4.1,given that a different gear types have been used in the research blocks in different years, there is also a low level of tag recapture in this area.
