The longline CPUE series for Inaccessible, Nightingale and Gough islands are GLMM standardised through to season 2024. 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, with those for Gough 2021+ having risen to also be substantially higher than the associated Itar value. There have, however, been slight decreases in CPUE for Inaccessible and Nightingale islands between the 2023 and 2024 seasons.
