Description:

Abstract:

Distribution and abundance of commercial clams were investigated, using a hydraulic Nantucket clam dredge and a Maryland soft-shell escalator clam dredge at 846 stations along the west and southeast coasts of Florida, during 1970 and 1971. Sunray venus clams, Macrocallista nimbosa, occurred along the entire west coast but were more abundant north of Tampa Bay and were found in commercial quantities only on the existing commercial Bell Shoal bed. Southern quahogs, Mercenaria carnpechiensis, were most abundant near passes along central and southwest Florida. In bays, both species were usually associated with seagrasses, but this was not noted in open Gulf collections. Both species were seldom collected beyond 9.2 m depths. The most abundant bivalve was the marsh clam, Rangla cuneata, confined to brackish areas of the Peace and Myakka Rivers. At lower salinities R. cuneata were larger and had more size classes.

Purpose:

The purpose of this data layer is to create a digital version of the sedimentary characteristics published by Godcharles and Jaap (1973) for inclusion in the usSEABED data collection.
