Power analyses of CEMP indices for penguins at Admiralty Bay and fur seals at Cape Shirreff and Seal Island
Abstract: We used the program MONITOR to conduct a set of power analyses for CEMP indices ... developed by the US AMLR Program. We consider CEMP indices A2, A3, A5, A6, A7, and A8 for penguins at ... describe the likelihood of rejecting null hypotheses stating that the slopes of linear models relating the ... actually exist. We estimated the power of rejecting these null hypotheses at three levels of? (the ...

Estimates of local biomass with uncertainty for Antarctic (Dissostichus mawsoni) and Patagonian (D. eleginoides) toothfish in research blocks in Subareas 48.6 and 58.4
estimated using a CPUE-by-seabed-area analogy method and Chapman tag-recapture methods following the advice ... of WG-SAM. The trend analysis decision rules developed by WG-FSA 17 were applied to provide catch ... limits for 2018/19. The only research blocks in which there were adequate recaptures were 486_2, 486_3 ... and 486_4. However, as the trend in all three of these research blocks was declining the revised catch ...
