ABSTRACT Field studies were conducted to compare quartzitic sandstone to siliceous limestone in its ability to collect oyster spat, and to determine if sandstone is a suitable cultch for oysters.
Quartzitic sandstone, unlike sedimentary sandstone, does not have loose abrasive sand particles and, unlike gravel, has a rough texture similar to the siliceous limestone used in this investigation.
