High Country News (May 28, 2014) — Environmental writer Ted Williams quotes Peter Moyle in an op-ed rebutting claims by recreational gold-dredgers that the activity does not harm fish and might even help them.  “'Is churning up hundreds of square meters of river bottom worth the 3.4 ounces of gold the average dredger collects in a season?' inquires fisheries professor Peter Moyle of the University of California at Davis. Moyle does fish counts with a mask and snorkel, and he reports a striking lack of fish in dredged waters."
