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 ...

Recommendations on rock lobster TACs for the Tristan group of islands for the 2015/16 season.
, 2022 OMPs have recently been accepted as the basis to recommend TACs for Inaccessible and Gough islands. Given that for Inaccessible and Gough the recent catch rates have been above the associated OMP’s target catch rate, the OMPs indicate increases to the TACs for both islands for the 2015 season:Inaccessible: 73 MT to 77 MTGough: 100 MT to 105 MTHigh ...

Initial Results in the Development of a Revised OMP for Tristan da Cunha island rock lobster
, 2022 An OMP for setting the TAC for the rock lobster fishery at Tristan da Cunha island was developed and implemented in 2013 (Johnston and Butterworth 2013). The operating model (i.e. the underlying stock assessment model used to simulation test the candidate OMPs) at the time (OM_2013) was fitted to GLM standardized CPUE for the period 1994 2012.

Further updates to the 2013 Tristan da Cunha rock lobster assessment
, 2023 The Tristan da Cunha assessment reported in April is adjusted to take into account some minor coding corrections. Sensitivity tests lead to little change in estimates of current spawning biomass depletion unless the level of recruitment variability assumed is modified.
