Each year, the Iowa Department of Natural Resources (DNR) stocks millions of Hybrid Striped Bass to provide quality fishing to anglers. Hybrid Striped Bass, a cross between Striped and White Bass, inherit many of the best qualities of their parents, including fast growth and aggressive feeding behavior. Unfortunately, they may also inherit their parents' tendency to move up and downriver. We want to study the effect of fish barriers on the fish's ability to emigrate out of their home lake.
