Title: Bioavailability and Effects of Lingering Oil to Littleneck Clams (Protothaca Staminea) and Population Recovery Status in Prince William Sound

Project Year and Number: 2007: 070829

Restoration Category: Research

Injured Resources Addressed: Clams

Abstract: We will determine the biological availability and effect of Exxon Valdez lingering oil to littleneck clams, Protothaca staminea. Results of laboratory exposures of P. staminea to oiled sediment collected in Prince William Sound will be compared to results from individuals collected in situ at known oiled and unoiled sites. Molecular biomarker assays and tissue histology will be used to determine effects of lingering oil to growth, reproduction, and other physiological endpoints in the exposed clams. This information will be paired with a field assessment of clam abundance at sites surveyed in the 1990-2000 NOAA long-term monitoring program in Prince William Sound to determine if recovery endpoints that had not been met in the year 2000 have been attained in 2007.
