Abstract
Abundance estimates of the orange roughy in two spawning aggregations on the northeast Chatham Rise (ORH3B) were estimated from a hull mounted transducer acoustic survey carried out between 30 June and 20 July 2014 using FV San Waitaki. For the Old Plume, the estimated abundance was 17 668 t (CV 19%) and for the Rekohu Plume, the abundance was 40 066 t (CV 26%).
