N1 - Funding Information:
we thank D. Ferrell and NSw Fisheries for providing otoliths from NSw and LHI, and the crew of the australian Customs Vessel "arnhem Bay" for collecting fish at elizabeth and Middleton reefs. we also thank P. Bond, J. Shick, D. Hiscox, and D. Nobbs for providing assistance with the LHI collections. a. wells and G. Kelly provided invaluable logistical assistance. Comments by D. Ferrell, G. Kelly, and B.walther improved the manuscript. Funding and logistical support was provided NSw Marine Parks authority, the Department of the environment, water, Heritage and the arts, and by the NSw Saltwater Trust.

N2 - Yellowtail kingfish, Seriola lalandi (Family Carangidae), sustain important commercial and recreational fisheries in New South Wales (NSW), Australia. However, little is known about their population structure, particularly whether the kingfish around Lord Howe Island (LHI) comprise a distinct stock, separate from that of the NSW stock. We examined the otolith chemistry from juvenile kingfish collected from LHI, several NSW sites and Elizabeth and Middleton reefs (EMR) and compared those elemental signatures to the juvenile portion of adult otoliths collected from LHI to determine where the adults may have originated. Our results indicate a robust separation in otolith signatures from different locations (error rate of classification ranged from 3.5% to 9.9%), and suggest that a significant proportion of the adult kingfish sampled (28%) may have originated in the waters around LHI or nearby EMR. Further research may indicate that the management of kingfish in NSW waters could benefit from a more spatially explicit strategy.
