| Summary: | An updated GLMM standardisation of trotline toothfish CPUE data is presented which includes new data for the 2020 “fishing”-year. After a marked decrease in CPUE from 2015 to 2017, there has been a notable increase in the 2018 index, which is close to the larger values estimated for the first four years (2010-2013) of the series. Since 2018, the indices show a decline, but are still higher than the lowest values of the index for 2016 and 2017. |
