Trends in mean lengths and selectivities for Dissostichus eleginoides taken by longliners in Subarea 48.3
years in the depth distribution of effort have led to different length-specific selectivity curves ... applying in different years. Combined length-specific selectivity curves were estimated for each ... of the years 1997-2000. Notable differences were found amongst these, but there was a consistent tendency ... on the overall length-specific selectivity and that it is also likely that historical changes over years ...
