Abstract
The Powerboat CPUE series for Tristan was last updated in 2016 (MARAM/Tristan/2016/MAY/08) and took data for the 1994-20141 seasons into account. This GLM incorporated a method whereby the full GLM for Tristan can be rescaled to take into account the overall fishing efficiency changes informed by the data on fishermen’s names (available for only 2005-2007 and 2013-2016 seasons). This document updates this GLM analysis by incorporating data from the most recent 2016 season. A continued improvement in the 2016 CPUE is evident.
