A GLM method is described which is used to standardise the vessel CPUE data at Tristan. The vessel CPUE provides a more optimistic indication of stock status than the powerboat CPUE for the last three seasons. The 2018-2019 vessel GLM 2020 values are slightly above the Jtar target CPUE value, whereas the 2018-2019 powerboat GLM values are slightly below.
