An alternative strategy was adopted whereby the catch-at-age and mark-recapture data were restricted ... to the main trawl ground in which the longest time series of catches and the great majority of ... releases and recaptures of tagged fish were available. Catch and releases by age class for this fishery ... were obtained using proportions-at-length and fishery and year specific age length keys (ALKs) for ...
