RAZORBACK SUCKER TRANSBASIN MOVEMENT THROUGH LAKE POWELL, UTAH

摘要

We documented four razorback sucker (Xyrauchen texanus) individuals originally stocked in the San Juan River, New Mexico, subsequently recaptured in the Colorado and Green rivers, Utah. Each fish moved >550 km between stocking and recapture locations. The time between detections was 171-1,519 days. These movements included >= 210 km through Lake Powell. Lake Powell was previously thought to be a barrier between razorback sucker populations in the San Juan River and the Colorado and Green rivers.
