dc.description.abstract GLM methods are applied to compliance data (the “old” database) on confiscations (and abandonments) and on policing effort to estimate recent trends in the amount of rock lobster that is poached. Data for the period in 2016 when Operation Phakisa was launched with associated greatly enhanced levels of marine policing has been omitted from the analyses. The policing effort “sea patrols” has been omitted from the analyses as it has been deemed not to be relevant to rock lobster. The impact of omitting this policing effort type is minimal. The net effect of adding two further years of data suggests that the extent of poaching has increased slightly for Super-area 8+, but dropped more in the Super-areas 3+4+5+6+7. en_US
