OMPs are the agreed basis to recommend rock lobster TACs for all four islands of the Tristan da Cunha Group. The application of these OMPs using the most recent CPUE and survey data (and Vessel CPUE data in the case of Tristan) for input into the various OMPs result in the following TAC recommendations for the 2023/24 season:

The OMP for Tristan recommends a TAC for 2023 of 125 MT (2022 TAC 121 MT).

The OMP for Nightingale recommends a TAC for 2023 of 95 MT (2022 TAC 95 MT).

The OMP for Inaccessible recommends a TAC for 2023 of 111 MT (2022 TAC 106 MT).

The OMP for Gough recommends a TAC for 2022 of 110 MT+5MT rollover – 2MT overcatch=113 MT in total (2022 TAC=105+5MT rollover).

If an overcatch of more than 0.5 MT is taken at an island in a given season, that amount is to be taken off the TAC allocated for the following season. Thus a 2.2 MT overcatch at Gough must be removed from the allocated Gough TAC for the 2023 season as indicated above.
