Updated 2021 assessments of Jasus Tristani rock lobster at Gough Island

This paper provides an updated assessment of the Jasus Tristani rock lobster resource at Gough Island. This assessment includes updated data from the commercial fishery and biomass surveys for the 2018 and 2019 seasons. Data from the 2020 season are not included as they are not yet fully available. This assessment was last updated in 2018. The updated 2021 assessment has produced somewhat more optimistic results with respect to current spawning biomass. Current resource abundance is estimated to be 88% of pristine – a very healthy state. This updated assessment model will function as the underlying baseline operating model in the development of new 2021 OMP.
