  1. Comparison between the CCAMLR-2000 and KY 1988 surveys on environmental variability of krill in the Scotia Sea, Antarctica

    Abstract:  We assessed the environmental variability of Antarctic krill (Euphausia superba ... in December 1999. The Antarctic Surface Water mass, consisting of Winter Water and Summer Surface ... Antarctic Surface Water in 2000 reduced southward. Geographical distribution of krill, which approximates ... the area of the Antarctic Surface Water, in 1987/88 extended northward with high density. In contrast ...

  9. A von Bertalanffy growth model for Division 58.5.2 fitted to length-at-age data and a comparison of predicted with observed growth from mark–recapture data

    variable probability (VP) sampling of fish that were aged. Sub-sampling of random length frequency (LF ... ) data used to obtain the samples of fish for ageing used length-bin sampling involving a fixed sample ... size per bin. Estimation of the VB parameters used a definition of the maximum likelihood which took ... into account VP sampling due to length-dependent selectivity of trawl fishing and also accounted for ...
