Updated (and rescaled) Tristan island GLM-standardised Jasus tristani lobster Powerboat CPUE to take account of data for the 2024 season

The Powerboat CPUE series for Tristan island was last updated in 2024 (MARAM/Tristan/2024/APR/03), and took data for the 1994-20231 seasons into account. The GLM standardisation used incorporated a method whereby the full GLM time series for Tristan island could be rescaled to take into account the overall fishing efficiency changes as informed by the data on fishermen’s names (available for the 2005-2007 and 2013-2023 seasons only). This document updates this GLM analysis by incorporating data from the most recent 2024 season. Following a substantial increase in the 2023 CPUE relative to 2022, the 2024 powerboat CPUE has decreased slightly. The CPUE values for the last five seasons are substantially above the OMP target “Jtar” value.
