An updated GLMM standardisation of trotline toothfish CPUE data is presented which includes new data for the 2021 “fishing”-year. After a marked decrease in CPUE from 2015 to 2017, there has been a notable increase in the CPUE indices apart from a decline in the 2020 index. The 2021 index is the highest since 2012 and is close to the larger values estimated for the first three years (2010-2012) of the series.
