TRAFFIC and Compliance poaching indices are combined to provide an overall time series for poaching in absolute terms. This incorporates the same penalties as in the past on options that imply negative values for local sales of poached lobster, and large changes in the amount poached from year to year. The approach is applied to these indices separated by North and South areas. Two options for overall poaching time series, dependent on the value assumed for current local sales, are put forward, with the intention that they likely bound the range considered plausible.
