The longline CPUE series for Inaccessible and Gough islands are GLMM standardised through to 20141. For Nightingale, the fishery was closed for the 2011 season and catches were set at precautionary levels for the 2012 and 2013. The GLMM model thus excludes 2011 and 2012, although it now includes 2013 and 2014 for this island. Year, month, area, trap-type, soak time, depth and year-area interactions are treated as fixed effects, and year-month interactions treated as a random effect. For Tristan, for which the available powerboat data are more limited, a GLM with year and month as fixed effects is applied to the 1994 2014 data.
