Updated Compliance poaching trends for West Coast rock lobster from modelling the “old” and the “new” databases simultaneously
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 2021 now included. These results are compared to those obtained previously. The 2021 poaching index estimated for the southern Super-area 8+ shows a statistically significant decrease compared to 2020. In the case of the northern Super-areas (3-7), a statistically significant increase is evident. 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.
