Updates to the 2011 Tristan da Cunha group of islands assessment models and final assessment results

Johnston and Butterworth (2011a and b) provided input data and stock assessment details for the Tristan da Cunha group of islands. Recently, three further year’s catch-at-length data have become available and are listed here (Tables 1a-d).The authors have also used the longline catch-and-effort database from the three outer islands to calculate a “discard percentage” for each season 1997-2008. These data are listed in this document (Table 2).
