Abstract
Thirty-nine oyster populations were surveyed for disease in fall 2001. Perkinsus marinus was found in all areas sampled and prevalence exceeded 90% at all but 5 sample locations. In the James River P. marinus prevalence ranged from 88-100% at Deepwater Shoal, Horsehead Rock, Point of Shoals, Wreck Shoal, Mulberry Point, Swash, Long Shoal, and Dry Shoal. A lower prevalence was observed down river at Thomas Rock, 72%, and at Nansemond Ridge, 12%. The extremely low prevalence at Nansemond Ridge is likely age and density related; the oyster population was primarily comprised of spat; few small to market oysters were present at the site in October 2001.
