LSU researchers find impact of oil spill in marsh fish species
Date:9/26/2011

ularly sensitive to the toxic effects of oil and because marsh contamination occurred during the spawning season of many important species," Whitehead.

A major take-home message of the more than two decades of research following the Exxon Valdez oil spill in Alaska was that sub-lethal biological effects, especially those associated with reproduction, were most predictive of the long-term population-level impacts still apparent in many species such as herring and salmon. The current LSU study shows that early signals of similar kinds of sub-lethal effects are starting to emerge in an ecologically-important species following the Deepwater Horizon oil spill.

The LSU research group is currently following up with studies examining more direct effects of oil exposure on reproduction, development and growth.
