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 ...

Determination of a statistically based survey area suitable for hydroacoustic stock assessment of Euphausia superba in the Elephant Island, King George Island, Bransfield Strait area
of data from 1981, 1984 and 1978-1989 permitted resolution of inter-year differences in standing stock ... relatively uniform from year to year. Using only sub-area biomass leads to an ambiguous interpretation ... of the data as to whether high or law standing stock is due to low production (ie. "good" year vs ... . “bad” year) or differential effects of migration. Using the total of both sub-areas the survey area can ...
