Abstract : Dow Chemical USA carried out a three-phase program of research and demonstration that was sponsored by the U.S. Army Corps of Engineers Dredged Material Research Program between 1973 and 1978. The first phase consisted of chemical analyses of dredged material and 96-hr, auto bioassays which exposed penaeid shrimp to dredged material in seawater. The dredged material was free of significant concentrations of heavy metals, pesticides, and waste metabolites; bioassays indicated that the material was not toxic. The second phase consisted of simulated containment area studies in 1/4-acre ponds. This phase concluded that brown shrimp (P. aztecus) grew faster and larger in dredged material treatments; treatments required less fertilizer; and no extraordinary mortality was noted in dredged material treated ponds. The third phase was a field demonstration in a 20-acre portion of an actively used containment site. The field demonstration experienced significant problems.
