INCORPORATING SAMPLING VARIATION AND RANDOM READER ERROR INTO CALCULATION OF EFFECTIVE SAMPLE SIZE IN THE APPLICATION OF AGE LENGTH KEYS TO ESTIMATION OF CATCH-AT-AGE PROPORTIONS
accounts for both the variation associated with sub-sampling of the random length frequency (LF) sample for ... parameter estimate obtained from simulated samples of age frequency data. These samples are obtained using ... Monte Carlo multinomial replicates of the observed age length key (ALK) with each ALK used to generate a ... replicate age frequency sample. For each replicate a random draw of the ageing error matrix is taken and ...

Precautionary management of the Antarctic krill fishery at small spatial scales in the context of regional climate variability: pros and cons of coastal buffers, closed areas and move-on rules
changes in the oceanic domain add to the complexity of managing the Antarctic krill fishery, particularly ... at small spatial scales. We present an example during the early Austral summer of 2015/2016, when sea ... plausible that removals of even small amounts of krill could have reduced foraging opportunities.

Possibility of predicting sea-ice concentration (SIC) in research block (RB) 48.6-5 (Southern part of Subarea 48.6) using sea surface temperature (SST) in RB 48.6-2 (Northern part of 48.6)
Abstract: It was reported at WG-SAM-2019 that the sea ice concentration (SIC) of RB ... 48.6-5 corresponded well with the dynamics of monthly sea surface temperature (SST) anomaly in RB ... 48.6-5. However, in the prediction of SIC in RB 48.6-5 using the monthly SST anomaly ... , consequently there is very little information on the SIC during this period. However, the SST of RB 48.6-2 can ...
