Effectiveness of Conservation Efforts

In the early 1800’s half a million adult Atlantic Salmon were returning to US rivers annually.

In 2001 the estimate was 1,050 returning fish.

780 (90%) of which returned to only one river in Maine called the Penobscot

In 2002 871 (estimate returned)

In Nov 2000 US F&W listed Atlantic Salmon as endangered under the Endangered Species Act

Returns in 2007 were estimated at 940 salmon and more than double at 2,000 fish in 2008.

Still, that’s less than 0.5% of the original number of returning fish.
