Abstract

Oysters from 48 Gulf of Mexico sites were examined for presence and infection intensity of the endoparasite, Perkinsus (=Dermocystidium) marinus (Macklin, Owen, Collier, 1950) as part of NOAA's Status and Trends Mussel Watch Program. Prevelance exceeded 75% at 25 sites. Infections intensity did not vary with sex or reproductive stage. Latitude, total polynuclear aromatic hydrocarbon (PAH) content and industrial and agricultural land use significantly dependent, suggesting an impact of spawning frequency on uptake and depuration. P. marinus analysis complements the use of pollutant body burden for determining change in environment quality because it responds differently than pollutant body burden to the biology and ecology of the oyster.
