Wild Pacific Oysters:
- establish on intertidal rocky reefs
- compete for food with farmed oysters and native molluscs

- can be host for Pacific Oyster Mortality Syndrome (POMS).
Wild Pacific Oysters pose a risk to the oyster aquaculture industry through competition and their potential for hosting disease.

Recreationally harvested bivalve molluscs (oysters, cockles, mussels, pipis, scallops) and abalone should not be consumed at present due to the algal bloom and potential presence of brevetoxins. For more information see Health advice.
