Pendrell Sound Oyster Spatfall Monitoring Project Background (2009)

May 2009 – Oyster seed supply to the BC shellfish farming industry tends to be inconsistent, if unreliable.  This reality is a result of various factors including: (1) the nature of the industry and its ability to accept and finance seed inventory when it is available from hatcheries, and (2) oceanographic and biological challenges of producing seed past the larval stage in hatchery settings.  Indeed, in recent years some of the industrial shellfish hatcheries in the Pacific NW have been challenged by highly complex oceanographic variables – so much so that in 2007 and 2008, the lack of seed supply was considered an emergency situation for the industry.  Adding to the insecurity of seed supply in BC is the fact that (at present) the vast majority of Oyster seed in BC is imported from US hatcheries – to which, given political boundaries, access could be denied if there were disease outbreaks or other political issues arising.

The creation and security of a new supply of seed for BC has been a topic of discussion in the industry for years.  One proposed solution to the problem is the development of new shellfish hatchery resources in BC.  However, this is controversial given funding and administrative issues.  Another proposed solution is to seek new international sources of seed, but challenges with this source include genetics, international trade and aquatic animal health issues.  Yet another potential source of Oyster seed is thePendrell Sound natural Oyster set that has been a mainstay of the BC shellfish industry for years.  While the natural Oyster set may not be considered a viable option to service the whole BC shellfish farming industry, there are numerous companies that are indicating a renewed interest in utilizing this natural resource as a source of Oyster seed in their commercial operations.
