| Summary: | Development of a revised OMP (OMP 2020) for the Tristan island rock lobster resource first leads to a recommendation to include the annual Edinburgh/GS CPUE and the biomass survey index as well as the Tristan powerboat CPUE index as inputs to the formula to provide an annual TAC recommendation. Following an extensive comparison exercise, two options are put forward as candidates for the revised OMP: CMP1 and CMP2. Both reflect slightly less risk of undue resource depletion than under the current OMP 2016. CMP1 is very similar to that current OMP, and is expected to maintain annual TACs close to 120 MT. In contrast, under CMP2 TACs would be expected to increase slightly over the next decade, accompanied by a slight decrease in the catch rate compared to that under CMP1.
