http://gallery.usgs.gov/ en-us A list of the latest audio files and podcasts added to the U.S. Geological Survey's Multimedia Gallery (http://gallery.usgs.gov). http://gallery.usgs.gov/images/USGS.gif http://gallery.usgs.gov/ In this episode we take to the water and accompany a USGS field crew as they collect largescale suckers (Catostomus macrocheilus) along the lower Columbia River. Using a boat equipped with specialized shocking equipment, researchers stun nearby fish, allowing them to be easily collected and examined. Join us, as we explore how native fish are used to determine the water quality and ecological health of our local rivers, only in this month’s episode of the Oregon Science Podcast.
