The longline CPUE series for Inaccessible and Gough islands are GLMM standardised through to 20131. For Nightingale, the standardisation remains to 2010 only, as the fishery was closed for the 2011 season and catches have been set at precautionary levels for the 2012 and 2013 seasons. 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 1994-2013 data.
