A note on relating krill CPUE measures to abundance trends
Abstract: A crude mathematical framework is developed to describe krill abundance in terms of ... selected parameters of various aggregation behaviours exhibited by krill (Euphausia superba Dana). The ... relationship of combinations of these parameters to various possible measures of catch-per-unit-effort (CPUE ... ) for the Antarctic krill fishery is considered. The combined index of catch-per-hour of trawling ...

Assessment models for Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRUs 88.2C–G for the years 2002–03 to 2010–11
assessment model of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 covering SSRUs 88.2C, D, E, F ... , and G (SSRUs 88.2C–G). For modelling purpose, we split the region into two fisheries: south of 70.2° S ... where smaller fish are typically caught and effort has been light; and north of 70.2° S where larger ... fish are caught and most of the effort has been concentrated. For our reference case we used a selected ...
