Abstract
This report documents the age determination protocol for orange roughy (Hoplostethus atlanticus), an important New Zealand deepwater finfish species. Digital image examples of otolith preparations are presented and fully illustrate the zone interpretation used in determining fish age for this species. Associated difficulties and idiosyncrasies related to ageing prepared otoliths are also documented.
