A draft protocol for a sublethal sediment bioassay using the juvenile stage of Neanthes sp. (polychaete) was developed as part of a bioassay test demonstration study conducted for the Seattle District of U.S. Army Corps of Engineers and the Puget Sound Dredged Disposal Analysis (PSDDA) study. The draft protocol for the Neanthes sediment bioassay involved measuring survival and change in biomass (total and individual) following exposure to test sediments. The purpose of the study was to test exposure conditions incorporated into the draft protocol and, using the test results, establish the basis for a final protocol. The report describes the results of the following test conditions for the sublethal sediment bioassay. The optimal number of Neanthes that should be placed in each exposure chamber. The level of food ration that should be provided to each exposure chamber. Whether the test can be conducted using a static exposure system. Whether the length of the exposure period could be shortened from the current 20 days. Whether sediment grain size has an effect on increases in worm biomass during the exposure period.
