Abstract
This report describes the shell dredging industry in Texas, Louisiana, Mississippi, Alabama, and Florida. Total annual output of oystershell and clamshell from 1912 to 1969 and production and value by state from 1960 to 1969, cost of production and transportation, and industry structure including number of companies, estimated employment, physical equipment, and capital investment are presented. Controls for the industry imposed by states and the federal government through taxation and leasing systems are summarized. The nature of shell deposits and exploration, dredging, and processing equipment and methods are described. The report considers the environmental impact of shell dredging, especially that of disturbance and redeposition of bottom sediments.
