Download FAR 2017/24 - An investigation of otolith shape analysis as a tool to determine stock structure of ling (Genypterus blacodes)

Otolith shape analyses were found to usefully inform the stock structure of ling in New Zealand. Otoliths from Chatham Rise and Sub-Antarctic were correctly allocated to area with a success rate of 77.4%, a level indicative of a differentiation between ling from these two areas. For a north-south Sub-Antarctic comparison, a success rate of 50% strongly indicated no differentiation.
