Effects of photoperiod and mechanical stress on Olympia oyster physiology

A research proposal by SAFS student Bradley Chi.

Since its decline from commercial success, the population size of Olympia oyster (Ostrea lurida), the native oyster species to the Pacific Northwest, has significantly diminished. As a slow growing oyster with strict settling conditions, recovery of Olympia oyster has faced significant challenges. Increasing the growth rate of these species would benefit the restoration and commercial fishery possibilities of O. lurida. This study aims to deduce the effects of photoperiod and mechanical stress on growth in Olympia oyster. The effects of treatment will be measured by quantifying gene expression of growth related genes in the animals. Results of this work may be useful in future policies concerning Olympia oysters.
