Description
Summary: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 for input result in the following TAC recommendations for Tristan and Nightingale. The OMP for Tristan recommends a TAC for 2021 at 120 MT (2020 TAC 120 MT). The OMP for Nightingale recommends a TAC for 2020 at 93 MT (2019 TAC 89 MT). 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 2.3 MT overcatch at Tristan for the 2020 season must be removed from the allocated TACs for the 2021 season.
