Updated 2021 GLMM-standardised lobster CPUE from Inaccessible, Nightingale and Gough islands from the Jasus tristani fishery
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.
