Environmental Effects of Dredging. Preliminary Protocol for Conducting 28-DayChronic Sublethal Sediment Bioassays Using the Estuarine Amphipod Leptocheirus plumulosus (Shoemaker)

摘要

This technical note describes a preliminary protocol for conducting a 28-daychronic sublethal sediment bioassay using the estuarine amphipod Leptocheirus plumulosus. End points for this test include survival, growth, and reproduction. This protocol provides conditions for conducting the 28-day bioassay and procedures used for sediment storage and handling, laboratory culture, preparation of test chambers, reference toxicity tests, test acceptability, and data analysis.
