Impact of Exxon Valdez Spill on Fish Far Greater Than Thought: Study

"Federal scientists may have found a link between the 1989 Exxon Valdez oil spill and a decline of herring and pink salmon populations in Prince William Sound.

In a study published Tuesday in the online journal Scientific Reports, researchers from the National Oceanic and Atmospheric Administration (NOAA) found that embryonic salmon and herring exposed to even very low levels of crude oil can develop heart defects.

Herring and pink salmon juveniles that were exposed to crude oil as embryos grew slower and swam slower, making them vulnerable to predators, said John Incardona, a research toxicologist at NOAA Fisheries' Northwest Fisheries Science Center in Seattle, in a prepared statement".
