Abstract

Variation between distinct natural markings of freckled hawkfish (Paracirrhites forsteri) could allow in-situ identification of individuals from underwater photography. Receiver Operating Characteristic (ROC) analysis was used to assess the ability of I3S software to assist in discriminating between images of P. forsteri individuals. Our results show a high discriminant ability of I3S to differentiate between unlike individuals and identify images of the same individual. The ability to use automatic computer-aided assistance in this species will allow future research to explore behaviour and movements of individuals in the wild.Key words: I3S, model species, natural marks, Paracirrhites forsteri, population dynamics, ROC analysis
