✦ Synopsis

The null hypothesis for t,his research was t.liat oyster parasit.es and disease were not associated with incre:ised thermal loading in the Chesapenke-L)ela\r.are area. The American oyster Crasso-&en t-irginica (GXELIX) was held at a reference station and a test station in the Chesapeake a.nd Dehwarr Bay area for a year. Oysters from the four stations were sampled mont.hly for histological studies and parasite incidence together with t.he infestat.ion of the polychaetoiis annelid Polydorci ncebsteri. The incidence of parasites nnd disease conditions from histology was negligible. Based on these results the null hypothesis was arcepted, that oyster parasites and diseases did not increase with increased thermal loading. However, infestation of the oyster commensal P. zcrbsteri inrreased with increased temperatiire.
