Stream-Born Chemicals Prevent Trout From Sensing Predators
Among the dangers inherent in polluting our streams and rivers with persistent chemicals, scientists now say that pesticides commonly found in all native waters prevent trout from sensing predators. “Specifically, they could not sense their distance from a nearby predator. This impairment raises the likelihood that it might, in the wild, swim directly into range of a hungry grizzly bear. Over time, this inability could have dire consequences for the fish population and its chances for long-term survival.” Michael Ricciardi on EcoWorldly.com.
