Updated results are given for an approach which simultaneously models the “old” and the “new” databases as recommended by the Panel for the 2018 International Fisheries Stock Assessment Workshop, with poaching data for lobster for 2022 now included. These results are compared to those obtained previously. The 2022 poaching indices estimated for the southern Super-area 8+ and the northern Super-areas (3-7) both show a statistically significant decrease compared to 2021. A three-point smoothing approach adopted previously is used for converting the poaching series obtained into the outputs to be used for the input series to the assessments.
