Seawater extracts of marine sediments from two areas were added to copper‐enriched seawater in which the prefeeding stages (egg, NI, NII) of Euchaeta japonica (Copepoda: Calanoida) were maintained. Survival with the sediment extracts was greater than without, indicating an ability of some part of the extracted material to reduce the toxicity of the copper. The effect of the extracts was compared with that of a synthetic chelating agent to provide an “equivalent” value.
