An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort
Abstract: A new method for estimating illegal fishing effort is put forward. The results from ... this new method are similar to the Agnew and Kirkwood method and this suggests that the current method ... observations reflects zero illegal fishing. The new method performs better in the case of zero detections and ... can potentially better handle the evasion of detection by illegal activity. Both the new and the ...

Preliminary standardised CPUE analysis of the New Zealand toothfish fishery in Subarea 88.1 from 1997/98 to 2001/02
Abstract: This report provides the first analysis of standardised catch per unit of effort (CPUE ... ) from the exploratory fishery for Antarctic toothfish Dissostichus mawsoni, which has operated in ... Subarea 88.1 for five seasons, from 1997 to 2002. Two analyses are presented. The first (all-ground ... ) analysis reviewed catch from 1998 to 2002 (excluding the 1997 season as insufficient data were available ...
