Catch per unit effort (CPUE) is developed for subarea 48.6 from data covering 2004/2005 to 2017/2018 fishing seasons. General Linear Models and General Linear Mixed Models were applied to these data to extract annual time series trends that may be of use in the fitting of stock assessment models for Dissostichus mawsoni (D. mawsoni) in the area. The entire fishing area in 48.6 which is covered by various research blocks is treated as a single area and the developed trends are for the entire subarea. The trends from these models reflect stable to a slight increase in CPUE since 2013 which might be reflection better management since research block were introduced in 2012/2013 fishing season.
