Extending the time series of catch-weighted length frequencies
Abstract: The standard procedure used to extract catch-weighted length frequencies can only make ... use of CCAMLR data for D. eleginoides in Subarea 48.3 collected in the seasons 1992/93 and from 1994 ... /95 onwards. The procedure cannot use the earlier data collected between 1984/85 and 1991/93, and data ... from 1993/94 because of a mismatch in Flag State which presently occurs between the length and catch ...
