Atlantic rangia Rangia cuneata Adult. 2 cm (from Fischer 1978) Common Name: Atlantic rangia Scientific Name: Rangia cuneata Other Common Names: common rangia (Nelson et al. 1992); marsh clam (Burdon 1978); brackish water clam, road clam, wedge clam (LaSalle and de la Cruz 1985). Classification (Turgeon et al. 1988) Phylum: Mollusca Class: Bivalvia Order: Veneroida Family: Mactridae Value Commercial: The Atlantic rangia has been utilized for several thousand years along the Gulf coast, begin- ning with the Native Americans who made this clam a part of their diet (Tarver 1972, Tarver and Dugas 1973, LaSalle and de la Cruz 1985). The commercial value of this clam in now mainly in the use of its shell (both fresh and fossil) in the manufacture of cement, glass, chemicals, chicken and cattle feed, wallboard and other building products, agricultural lime, road con- struction and as fill in nearshore oil exploration (Tarver and Dugas 1973, Arndt 1976, Fischer 1978). Rangia shell is also used as substrate to enhance oyster settlement in Florida and Louisiana (MacKenzie 1996). Rangia are sometimes used for blue crab bait and some human consumption (Godcharles and Jaap 1973, LaSalle and de la Cruz 1985). Preparations include chopped clam dishes, chowders, soups, and either raw on the half shell, or steamed with rice dishes (Fischer 1978). It has also been canned occasionally for food products (Pf itzenmeyer and Drobeck 1964, Tarver and Dugas 1973). Hand-collected rangia are sometimes brought to cannery processors and added to hard clam catches (Fischer 1978). Recreational: Recreational harvest of Atlantic rangia is not significant in Gulf of Mexico estuaries. Indicator of Environmental Stress The Atlantic rangia filter feeds on detritus, and is therefore susceptible to the accumulation of pollutants from the particles on which they fee
