Do Different Methods Provide Accurate Probability Statements in the Short Term?
Restrepo, V. R.; Patterson, K. R.; Darby, Chris; Gavaris, S.; Kell, Laurence T.; Lewy, P.; Mesnil, Benoit; Punt, A. E.; Cook, R. M.; O’Brien, C. M.; Skagen, Dankert W.; Stefánsson, Gunnar (ICES CM documents, Working paper, 2000)The performance of uncertainty estimation procedures was evaluated with respect to accuracy. A confidence statement is said to be accurate if the confidence point achieves the desired probability coverage. A Monte Carlo ... -
Is current management of the Antarctic krill fishery in the Atlantic sector of the Southern Ocean precautionary?
Hill, Simeon; Atkinson, Angus; Darby, Chris; Fielding, Sophie; Krafft, Bjørn Arne; Godø, Olav Rune; Skaret, Georg; Trathan, Phil N.; Watkins, Jon L. (CCAMLR;WG-EMM-16/21, Conference object, 2016-06-15)This paper is a revised version of WG-EMM-15/28, which uses a question and answer format to explain the management of the Antarctic krill (Euphausia superba) fishery in the subareas 48.1 to 48.4, and current knowledge about ... -

Updating the Antarctic krill biomass estimates for CCAMLR Subareas 48.1 to 48.4 using available data
Hill, Simeon; Atkinson, Angus; Darby, Chris; Fielding, Sofie; Krafft, Bjørn Arne; Godø, Olav Rune; Skaret, Georg; trathan, phil; Watkins, J (;WG-EMM-15/28, Research report, 2015)We present a novel index of Antarctic krill biomass in CCAMLR subareas 48.1 to 48.4, based on data from scientific nets and covering the years between 2000 and 2011. The annual biomass variation was significant (CV=73%) ... -
Validating three methods for making probability statements in fisheries forecasts.
Patterson, K. R.; Cook, R. M.; Darby, Chris; Gavaris, S.; Mesnil, Benoit; Punt, A. E.; Restrepo, V. R.; Skagen, Dankert W.; Stefánsson, Gunnar; Smith, M. (ICES CM documents, Working paper, 2000)We report on a test of three methods that have been used by ICES in making probability statements about fisheries forecasts to management agencies (XSA/WGMTERM, ICA/ICP, and a stochastic projection method that was first ...
