USGS research on invasive sea lampreys

USGS scientists perform research on invasive sea lampreys looking for ways to minimize their ability to use fish passages and gain access to new habitats. Researchers have found that using attachment-inhibiting surfaces can break the suction seal sea lampreys need for movement, preventing these non-native pests from using their suckers to climb up a fishway and spread upstream.
