formulated sediments as substrates for culturing benthic 

 invertebrates in the lab (Watzin & Roscigno, 1990). 



An invertebrate common to the Bering and Chukchi Seas 

 that might be suitable is Ampelisca. Their importance as food 

 sources for many marine mammals makes species from this 

 genus likely candidates for a sediment toxicity test. Until more 

 region-specific test species are available, organisms such as 

 Anemia and Pyrocystis will serve as reliable surrogates. 



With more developmental work, these two species can be 

 used as part of an integrated ecotoxicological monitoring 

 program that can provide useful information toward establishing 

 baseline conditions for the Bering and Chukchi Seas. The 

 anticipated assaults from oil development can be monitored so 

 that impacts to these ecosystems can be minimized.
