Abstract
Larvae of seven species of estuarine fishes (Atlantic menhaden, Brevoortia tyrranus; pinfish, Lagodon rhomboides; flounder, Paralichthys dentatus, P. albigutta, P. lethostigma; spot, Leiostomus xanthurus and Atlantic croaker, Micropogon undulatus) were exposed to sea water extracts of sediments from Charleston Harbor, S.C., for periods of time up to 14 days. Survival of the larvae in various concentrations of the extracts was measured. Survival of the larvae was affected at the highest concentrations of extract tested and indications are that different species of fish have different survival rates. In the selection of disposal areas for dredged material, consideration should be given to its relative toxicity to organisms.
