Ocean Acidification Impacts on Pacific Shellfish (Workshop)
July 2010 and 2011
Costa Mesa, CA


Many have certainly read reports about the effect of ocean acidification on corals in the tropical and subtropical seas. As the water becomes more acidic, it becomes more corrosive to organisms that have carbonate exoskeletons, such as corals. Shellfish like clams, oysters and mussels also have carbonate exoskeletons, so there is growing concern that this increased acidity is also beginning to affect our local shellfish fisheries.

In the summer of 2010, USC Sea Grant along with Sea Grant programs in California, Oregon and Washington and shellfish industry representatives co-sponsored a workshop with representatives from the west coast shellfish industry to open a dialogue among shellfish harvesters, shellfish aquaculture growers, and researchers at the forefront of ocean acidification studies (see partners below). A 6-page brochure was developed subsequent to this first meeting (click on the image to the right to download a version).

There have been subsequent workshops and meetings over the last year that build on the work of the inaugural Summer 2010 workshop.

Another important result of the first workshop was the creation of the California Current Acidification Network (C-CAN). This network is composed of shellfish growers/harvesters, researchers, and state agencies. They are working to tackle workshop recommendations, which include establishing best practices and standardized research methods and developing a data exchange portal for information regarding ocean acidification processes affecting west coast fish and shellfish. They now have their own website and listserver. For more information, please visit: http://c-can.msi.ucsb.edu/
