A recent report from Virginia Institute of Marine Science brings new light on oyster species for USA East Coast aquaculture. Studies from several agencies found that the Asian oyster (Crassostrea ariakenisis) may be subject to disease in American waters. The oyster had been under intense study as a possible replacement for native East Coast oysters which have been decimated by disease. The native oyster (Crassostrea virginica) has declined in the last half century from a number of factors, including the diseases MSX and Dermo. Early tests in Virginia and other areas showed potential for Asian oysters as a candidate species for aquaculture operations along the Virginia coast and in the Chesapeake Bay watershed. Further experiments in North Carolina discovered that C. ariakenisis was vunerable to a third waterborne parasite. The experiment found that a parasite from the Bonamia family was the cause of high mortality of young Asian oysters. Parasites of the Bonamia genus are well known for causing oyster deaths worldwide. The native Virginia oyster appears to be unaffected by the organism. Studies found that the Bonamia pathogen may have been introduced but is established along the Eastern seaboard and possibly the Chesapeake Bay region. The parasite is said to primarily affect seed-size oysters. The effects of the disease is also dependant on water salinity. Bonamia appears to be prevalent in salinities of 20 PPM and higher. Activity is very high around 25 PPM and levels of 18 PPM or less appear to be less hazardous to oysters. Outbreaks appear to be associated with high water temperatures. Research shows that two oyster species may provide breeding environments for the parasite. In addition to the Asian species C. ariakenisis, the parasite also attacks the crested oyster (Ostrea equestris), a species common in North Carolina waters. Apparently the crested oyster is less affected by the disease but does harbor it.

The National Oceanic and Atmospheric Administration (NOAA) finalized and adopted the 10-Year Plan for Marine Aquaculture on October 30, 2007. The plan is intended to guide the agency as it works toward establishing marine aquaculture as an integral part of the U.S. seafood industry and as a viable technology for replenishing important commercial and recreational fisheries. The plan provides specific goals for the NOAA Aquaculture Program and an assessment of the challenges the agency will face in its effort to reach its goals.
To download an electronic copy of the plan, go to: http://aquaculture.noaa.gov .
To obtain a hard copy of the plan, send your mailing address in an e-mail to NOAA.Aquaculture@noaa.gov ; or fax your request to the NOAA Aquaculture Program at (301) 713-9108.

Mid-Atlantic - Chesapeake Bay Shellfish Aquaculture Planning Project is Underway
In cooperation with NOAA National Sea Grant <http://www.seagrant.noaa.gov/> , the NOAA Chesapeake Bay Office <http://noaa.chesapeakebay.net/> has funded Maryland Sea Grant to facilitate a Chesapeake Bay Shellfish Aquaculture Planning Project to guide future efforts and investments in the Chesapeake Bay region. The project will engage a broad group of stakeholders in both Maryland and Virginia. Maryland Sea Grant is working closely with Virginia Sea Grant Extension to:
* Organize meetings, workshops, and conferences between growers, harvesters, and other regional interest groups to assess the current status of oyster aquaculture and to develop recommendations for industry expansion;
* Engage industry and academic professionals nationwide to gain knowledge of successful production methods used in other regions;
* Identify and prioritize constraints to the development of private sector oyster aquaculture in Maryland and Virginia;
* Describe needs and opportunities for hatchery production, research & demonstration projects, education, public policy, and marketing & economics;
* Produce a project report that can serve as a plan for development of a sustainable and environmentally beneficial oyster aquaculture industry in the Chesapeake region.
An informational brochure describing the project is available online <http://chesapeakebay.noaa.gov/docs/ShellfishAquacultureBrochureTrifold.pdf> . For more information, contact Jamie.King@noaa.gov.
