The Olympia oyster (Ostrea lurida), Washington's only native oyster, was brought to near extinction during the last century due to overharvesting and habitat destruction. Populations have failed to recover naturally leading to a need for active restoration. O. lurida provide ecosystem services including filtering water, providing habitat and food, and increasing the overall diversity of the ecosystem. In order to restore the Olympia oyster to healthy population numbers in Puget Sound, WA, spatial patterns and population connectivity of O. lurida veliger larvae need to be studied to provide efficient and targeted restoration for the species. It can be difficult to determine larval transport patterns due to high larval mortality, small size, difficult identification, and long potential dispersal distances. By following methods of Carson et al. 2010, using trace elemental fingerprinting, it is possible to trace veliger larvae back to predicted natal populations. This is achieved by comparing the chemical signatures of settlers, veligers and brooded larvae using analysis by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). During the 10-12 day brooding period, trace metals from larval bay of origin are embedded into the natal shell during early life, leaving a record of past locations in the shell. Analyzing samples collected at natural and restored sites of O. lurida in Puget Sound, WA allow us to compare site and spatial variability. These results will shed light on the dispersal and larval behavior of O. lurida which could inform restoration of native shellfish to create a network of self-sustaining sub-populations.
