Bioassays conducted at this laboratory have shown commercial penaeid shrimp to be one of the most sensitive crustaceans to organochloride pesticides. Nevertheless, little is known about residues in the organs of shrimp or the sites of pesticide localization. We therefore exposed shrimp to low concentrations of DDT (0.05 to 0.2 p.p.b., parts per billion) in the laboratory for extended periods to compare residues accumulated under controlled conditions with residues in natural populations.
