| Abstract |
The protocol is for conducting a bioassay in which the survival and change in biomass of juvenile Neanthes sp. are determined following a 20-day exposure to test sediments. Parameters measured to determine the effects of exposure include mortality, total biomass, and average individual biomass. Sediments can be either naturally occurring, field-collected samples, or sediments that have been experimentally modified (e.g., sediment mixed with other sediment to form a gradient of sediment types or sediment to which chemicals have been added). The Neanthes bioassay is conducted as a static renewal exposure, and food (i.e., TetraMarin) is provided to the test organisms during the exposure period to promote body tissue increases. Following the 20-day exposure period, all surviving worms are collected, dried to a constant weight, and total average individual biomass are determined. |
