The longline CPUE series for Inaccessible, Nightingale and Gough islands are GLMM standardised through to 2021. Year, month, area, trap-type, soak time, depth, sequential day and year-area interactions are treated as fixed effects, and year-month interactions treated as a random effect. The recent standardised CPUEs for Inaccessible and Nightingale continue to be high (well above the Itar level), with that for Gough being substantially higher than the 2020 value.
