Effects of Black Rock Harbor Dredged Material on the Scope for Growth of the Blue Mussel, Mytilus edulis after Laboratory and Field Exposures

A study was conducted to investigate residue-effect relationships between tissue residue concentrations and the scope for growth of the blue mussel, Mytilus edulis, after exposure in the laboratory and the field to dredged material from Black Rock Harbor (BRH), Bridgeport, Conn.

Description
Summary:A study was conducted to investigate residue-effect relationships between tissue residue concentrations and the scope for growth of the blue mussel, Mytilus edulis, after exposure in the laboratory and the field to dredged material from Black Rock Harbor (BRH), Bridgeport, Conn. A second objective included field verification of the laboratory results. A laboratory system was used to provide a constant exposure concentration ranging from 0 to 10 mg/l of suspended BRH sediment. Residue concentrations in mussels, particularly stable compounds such as polychlorinated biphenyls, were found to be closely related to exposure concentration. Scope for growth, clearance rates, and shell growth measurements were inversely related to BRH exposure and subsequent tissue residues, with concentrations as low as 1.5 mg/l of BRH material causing negative biological effects.
