dc.description.abstract This paper reports the updated biomass indices obtained from the annual (Leg1) biomass survey at each island. The index shows a much improved biomass index for Inaccessible, and a fairly constant but slightly positive trend for Tristan and for Gough. The Nightingale biomass index remains high following a sharp increase subsequent to the 2011 OLIVA event. There have been some changes over time in the size distribution, the most marked of which was a steady decrease in the mean length at Tristan which has turned around in the last two seasons. The percentage of females in the catch at Gough is about double that at the other islands. en_ZA
