Funded Activity Summary

Reporting of visible anchor tags by commercial fishers is believed to be biased in some circumstances. There is therefore a need to develop a fishery independent technique of identifying the origin of migrating whites lobsters so as to address the extent of movements of these animals between management zones, without having to rely on visible tags.

Objectives:
1. To investigate the factors affecting the carbon/oxygen isotope composition of the exoskeleton of western rock lobsters as a location specific chemical signatures for that species.
2. To apply these results as a method for determining the locality and depth (temperature) of a lobsters origin, at the time of its most recent moult.
