Abstract

Natural body marks on Sphyraena barracuda were recorded with digital images to identify individual fish. Over 18 months, 60 fish were photographed in situ, eight of which were re-photographed at later dates. Re-photographed fish were all large adults (>70 cm total length) and were all seen within 200 m of the site where they were originally observed 10-318 days prior. Over the same period and area, 116 fish were tagged using T-bar tags, yet none of these fish were recaptured. Natural body marks are thus an effective means of identifying and monitoring behaviour of individuals.
