The effectiveness of oyster shell, expanded shale, and tire chips as substrates for settlement of oysters, Crassostrea virgi11ica (Gmelin), was compared at four locations in the James River, Virginia, over three two-week time intervals in August and September, 1988. Only differences between substrate were significant (P < 0.001). Over all locations and time intervals, a significantly higher (P < 0.001) proportion of total oyster settlement occurred on oyster shell (63.8%) than on either tire chips (22.1 %) or expanded shale (14.2%).
