Four EV0S-ABL research projects on pink salmon are being conducted:
- Review and synthesis
- Toxicity to eggs
- Oiled spawning habitat
- Straying impacts
The ABL's oil toxicity studies on pink salmon have far-reaching
relevance, particularly for urbanized watersheds and estuaries of the
coastal U.S. In urbanized waterways, many coastal habitats have
continuous input of hydrocarbons due to runoff as development continues.
Of the 9,692 miles of United States coastline outside Alaska, over
two-thirds are considered urban. Studies in the literature estimate
that, on a per capita basis, the United States spills about a quart of
oil per person per year. Fifty million people spill more than 12 million
gallons of oil per year, which is equivalent to the Exxon Valdez
spill. Unfortunately, that quantity is spilled this year, next year, and
the years following. Given the high toxicity of PAHs to eggs, chronic
input of hydrocarbons in streams, bays, and estuaries may limit
recruitment of fish populations far more than was previously supposed.
