    Variants of GLM-standardised lobster CPUE for Tristan da Cunha for the 1997-2009 period
    (2010) Johnston, Susan J; Brandão, Anabela; Butterworth, Doug S
    Powerboat CPUE data for Tristan island are more limited (in terms of the associated data collected that might provide co-variates for a GLM-standardisation exercise) than the longline CPUE data for the outer three islands. Thus for the four GLM variants applied here to the Tristan powerboat CPUE data, only year and month have been used as fixed effect co-variates.. All four GLM variants show similar CPUE trends. After a steady increase over the 1994-2006 period, the standardised CPUE indices show drops over the following two seasons, with an increase for the most recent 2009 season.
