Phase-randomisation in an integrated assessment model for Antarctic krill
(Euphausia superba, hereafter krill). We fixed the parameters that were not estimated in any given ... configurations. The numbers of parameters estimated in configurations that were able to obtain an invertible ... objective value, the maximum gradient, the proportion of replicate trials that found the minimum observed ... invertible Hessian matrix. Configurations that estimated more parameters fitted the data better, but the ...

Developments towards an investigation of potential bias from the analysis of tag–release and recapture data in Ross Sea Antarctic toothfish abundance estimates
approach that uses the current data on catch (C2 data), tag-recovery effort and tag-release data from Dunn ... et al. (2005c), but ignores movements of tagged and untagged fish. The results suggest that as the ... spatial pattern of tag releases and recovery effort has changed over the years that the tagging programme ...
