Salmon Run - Prospects

Prospects

In 2009, NOAA advised that continued runoff into North American rivers of three widely used pesticides containing neurotoxins, will "jeopardize the continued existence" of endangered and threatened Pacific salmon. Global warming could see the end of some salmon runs by the end of the century, such as the Californian runs of Chinook salmon. A 2010 United Nations report says increases in acidification of oceans means shellfish such as pteropods, an important component of the ocean salmon diet, are finding it difficult to build their aragonite shells. There are concerns that this too may endanger future salmon runs.
