1. Trends in mean lengths and selectivities for Dissostichus eleginoides taken by longliners in Subarea 48.3

   Abstract:  At its last meeting, WG-FSA noted a declining trend in the mean lengths of toothfish ... of fish taken on individual longline sets from which length frequencies were sampled by observers and ... also that this trend was halted in 2000. A GLM analysis of these data shows that both area and depth ... are highly significant factors in explaining part of this variation over time, but not all of it ...
