The development of local biomass boiler manufacturing and assembly companies.
Individual heating systems also can take advantage of local biomass resources.
Estimates of local biomass presented in WG-FSA-17/42 were updated over the course of the meeting to include.
The Working Group agreed that, while it may be considered precautionary to use the lower local biomass estimate, it was important to understand the variance.
Dr Kasatkina noted that the local biomass estimation method used in WG-SAM-16/18 Rev. 1 was accompanied with significant uncertainty.
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 survey would also provide local biomass trends within the surveyed part of the SRZ to compare with trends in the open areas outside the MPA.
This larger than expected decline in the number of tagged fish recaptured through time might impact on the estimate of local biomass, and sensitivities were suggested to understand the size of the effect.
Where multiple plausible local biomass estimates were available,the more precautionary option was selected unless other evidence supported a higher local biomass.
In reviewing the methods, the Working Group agreed the following methods for the estimation of local biomass using the catch-per-unit-effort(CPUE) by seabed area analogy and Chapman mark-recapture estimate.
Where multiple plausible local biomass estimates were available, the more precautionary option was selected,unless other evidence supported a higher local biomass SC-CAMLRXXXII, Annex 6, paragraph 6.26 and Table 13.
Changes made throughout the course of the meeting to the R Markdown used to generate the local biomass were documented in a GitHub repository that was shared with Working Group members for review and comment.
Given the importance of this table to setting catch limits and research requirements in exploratory fisheries,there was a need to ensure clarity in the methods used to generate and update local biomass estimates.
In particular I refer to the sustainable production of local biomass, which is crucial to be effective at reducing greenhouse gas emissions.
The analysis suggested that there is sufficient signal in existing CEMP indices to detect reduced predator performance when krillbiomass is low or when local harvest rates are of similar magnitude as local biomass.
The Working Group noted that the estimates of local biomass used in the calculations in Table 5 were those estimated by WG-FSA-13, except for the estimates for.
The Working Group noted that additional analyses of historical ice conditions in these research blocks(see also WG-FSA-13/37) andof likely CVs of local biomass estimates associated with different numbers of recaptures, were informative.
These functional relationships empirically demonstrate reduced penguin performance in the Antarctic Peninsula region when local krillbiomass is low or when local krill catches are high relative to local biomass.
Some Members expressedconcern over the proposal, noting that clearer recommendations on local biomass estimates and stock distribution were needed for SSRUs 882A-B prior to making changes to the subarea boundary.
Furthermore, some Members recalled that the Simeiz presented a low effective tagging survival rate and tag-detection rate in the Ross Sea region(WG-FSA-17/36, Table 6), andthat this should be taken into consideration when calculating local biomass based on mark-recapture data from this vessel.
The Working Group was not able to evaluate this proposal in regard to the likelihood of generating a local biomass index and whether the proposed research was likely to test a hypothesis of relationship of fish in the research area to the overall stock.
The Working Group recalled that there had also been mixed success with ad hoc depletion experiments in the past in the Convention Area, and that the Spanish results confirmed that planned depletion experiments were also difficult to interpret andconvert into robust information on local biomass.
The Working Group noted the revised research plan and proposed local biomass estimates described in Table 13, using a revised number of tags released and available for a Petersen estimate(548 tonnes), and the base-case integrated model estimate of B2013 635 tonnes.
The Working Group noted that, consistent with the principles for research plans described in WG-FSA-17/13, the prospecting phase in any one area should belimited to one year, and that estimations of local biomass using CPUE by seabed area or Chapman estimates should be developed thereafter.
The Working Group requested that the CV of the de Lury estimates of local biomass be provided to WG-FSA to be used to consider appropriate catch levels in the experiment and the value of such experiments relative to other methods for estimating biomass for use in stock assessments.
The Working Group agreed that if tags are recaptured, then it should be possible in 2013/14 to compare the results of depletion-based,tag-based and CPUE-analogy-method-based estimates of local biomass for these locations, informing a useful review of how extending this experimental approach might lead to advice on stock status in these SSRUs.
Catch rates were used to provide estimates of the local biomass which differed between the 2015 and 2016 surveys due to the relative contribution of the CPUE collected in the areas surveyed; only three of 18 planned stations were conducted in the northern area due to the catch limit restrictions.
The Working Group noted that in the context ofdetermining appropriate catch limits, it is important to distinguish between estimates of local biomass obtained from within research blocks and estimates of abundance of the whole stock derived from analytical assessments to which the CCAMLR harvest control rules are applied.
The Working Group recalled that the local biomass estimates should not be considered as a biomass estimate upon which to set long-term catch limits for a sustainable fishery but they are designed to facilitate research and, therefore, it was important to define the period of that research.
To provide catch limit advice,the Working Group first estimated local biomass within each research block using all available methods, including the CPUE analogy method, Petersen estimates arising from tag recaptures and stock assessment outputs where these were available Tables 13 and 14.
