This video adapted from Nature describes efforts to protect salmon by killing and re-locating predators. Examples include paying bounty hunters to fish pikeminnow, trying to relocate terns and cormorants, and using non-lethal bullets to scare away sea lions. The segment concludes with a look at how scientists are counting current numbers of salmon passing through Bonneville Dam along the Oregon-Washington border.
This video is available in both English and Spanish audio, along with corresponding closed captions.
